1. Introduction
The supply chain system plays a vital role in the effective functioning of business processes. The term “supply chain”, defined as a network of information, goods, resources, and business activities, emerged and developed from logistics, marketing, production, and distribution [
1]. The coordination of materials, resources, information, and financial flows is an important aspect of a supply chain system. In a broader sense, a supply chain is also known as an inter-organisational flow of services with important units to consider, such as production, marketing, procurement, and finances. Businesses aim to govern and monitor supply chain processes with enhanced efficiency and accuracy in order to perform effectively. Gayialis et al. [
2] highlighted that high production levels, lower operational costs, fast-paced production systems, and enhanced sustainability strategies are currently some of the main objectives of organisations. As businesses have become more competitive than before, as a result of technological advancements and innovative implementations and adoptions, it is crucial to manage supply chain processes with more attentiveness and diligence [
2].
According to Popkova et al. [
3], technological innovations have improved process delivery and enabled organisations to meet sustainability criteria by streamlining business operations and increasing profit margins. Emerging technological solutions such as robotic process automation (RPA) have greatly improved and enhanced food processing and manufacturing and have helped supply chains achieve sustainability and a competitive advantage, as well as create value in business processes. Sustainable food production, which is safer, healthier, and more secure for human consumption, is currently one of the prominent and growing concerns for food supply chains. RPA helps food manufacturers to improve and speed up their business procedures to ensure the production of high-quality, healthy, and safe food with reduced operational and functional costs. In food production, it is extremely important to consider the economic growth and financial health of businesses as organisations are expected to cater to wider masses and a growing food demand, which is quite challenging, especially in a competitive business world [
4].
RPA is seen as an emerging technology that can accelerate business processes through the automation of repetitive, strenuous, and rule-based tasks in supply chain systems. RPA is often referred to as software robotics or “bots”, and follows instructions defined by the end-users to automate repetitive processes or activities in business organisations. RPA technology uses software bots in place of the human workforce to perform tedious tasks. The implementation of RPA technology not only facilities business processes by making them less complex, but also reduces human error to make supply chains more well synchronized, integrated, and systematic. Digital transformation, such as RPA, has attracted corporate attention as a result of several supply chain complexities, uncertainties, risks, and barriers due to increased globalization and wide-spread supply chains. Technological advancements such as RPA have gained popularity as they accelerate supply chain processes, and reduce the time, cost, and energy required to enhance supply chain operations. RPA’s promising benefits include value addition and a competitive advantage for supply chains, thus creating sustainability. Achieving sustainable value is the main concern of supply chains; RPA automates tasks and makes businesses less reliant on the human workforce, thus enhancing production levels, improving supply chain processes, and reducing operational costs, which create sustainability in supply chain processes [

The beef supply chain is highly fragmented, which makes its management system complex and challenging. Sustainable beef manufacturing and processing has attracted attention globally and is a cause of concern for beef manufacturers. The beef sector involves various stages that include complex procedures in beef production and involve system uncertainties and disruptions. The beef manufacturing supply chains constantly face supply chain risks and challenges related to high operational costs, beef productivity, quality, safety, and shelf life. The beef sector, a representative of the food industry, has social, environmental, and economic challenges. Growing awareness towards beef quality and safety raises concerns for beef manufacturers, who constantly strive to achieve sustainable value and produce nutritious, healthy beef at low operational costs. Process automation within beef supply chains facilitates work-flow management systems, eases complex and tedious tasks through process excellence, and reduces human error to speed up processes. Moreover, automation in the beef sector serves as a process facilitator that enhances supply chain performance and boosts task delivery, resulting in a higher output to satisfy the growing demand for beef. Sustainability-oriented innovations and solutions such as RPA could reduce supply chain risks through process acceleration and support the beef sector to reduce operational costs and meet sustainability goals. RPA further enhances employee-level efficiency as bots are able to work 24/7, unlike humans, on processing lines to manufacture high-quality, sustainable beef at a low cost. Technological breakthroughs such as RPA have the potential to enhance supply chain operations and satisfy customers by maintaining quality standards. Automation acts as a sustainability driver in beef supply chains to add value in business processes. Innovative approaches such as automation within the beef sector improve production levels, increase supply chain resilience, and make businesses more competitive [

Sustainability in beef supply chains is a constant concern and challenge for the beef industry [
11]. Beef supply chains are complex and large in order to cater to their dynamic structure and business system. Beef supply chains struggle to produce high-quality, nutritious beef due to the high financial costs and overhead expenses of production systems that companies install and implement for efficient beef production. The beef sector strives to achieve sustainable beef production to add value to their supply chains and satisfy the high customer demand due to growing consumer needs and requirements. Beef supply chains are fragmented and very complex across the world as well as in the UK with respect to their functioning, monitoring, and management. High production costs including labour work, machinery usage, technological adoptions, and organizational set-up are some of the financial aspects that are concerning for beef manufacturers. Manufacturing supply chains are seeking sustainable procedures and methods to ensure reduced financial burden and lower operational costs while aiming for higher production levels [
12]. This promising RPA technology allows beef supply chains to achieve sustainable production systems.
This research aims to investigate the financials aspects that are important to consider in the RPA adoption process. The study further analyses the financial barriers or risks that may potentially exist in the adoption process of RPA within the beef supply chain system. This study adopts the process model developed in previous research to conduct a ‘what-if’ scenario analysis based on financial parameters for the identification of financial barriers or risks in the adoption process of RPA that could potentially impact supply chain production levels, costs, and efficiency. Beef supply chain characteristics and features are critically analysed to understand the implementation process of RPA in the beef sector in an enhanced manner, considering the financial aspects. By simulating the business process model and considering the cost-related parameters, this study allows for the assessment and evaluation of the socio-economic benefits of RPA adoption, as well as how RPA can be adopted in a successful manner by eliminating financial barriers to create sustainability within beef supply chains.
This research rationale and its significance is crucial to discuss in order to further understand the aims and objectives of this work. The research supports that beef supply chains struggle to adopt the RPA adoption process because of cost analysis or financial reasons. Although RPA is a popular and widely used process for excellence and efficient supply chain functioning, there are no thorough evaluations related to the financial factors that influence its adoption and previous research lacks information related to the financial barriers or risks present in its implementation. The identification of the financial risks and barriers in the adoption of the RPA process requires critical research and investigation to fill the gap. The process models provided by authors in previous studies examined and investigated the beef supply chain from the perspective of operational efficiency, shelf life, and quality. This study is significant as it uses a simulation approach along with the previously formed process model, and analyses different scenarios based on financial or economic parameters to evaluate the best approach for adopting RPA in beef supply chains. This research uses the process model to analyse the scenarios using the financial parameters or factors that impact the RPA adoption process. Therefore, this study critically examines the process model using financial factors or parameters that are important to consider for effective adoption using a simulation-based approach. The model, depicting crucial beef supply chain stages, is tested and run to observe the production levels and costs at various stages of the supply chain. The simulation uses SIMUL8 software and the scenarios are analysed to observe the bottlenecks or barriers at various stages using a virtual simulation environment. The study considers cost-related factors that contribute to the successful adoption of RPA in beef supply chains to ensure sustainable beef production. It further depicts the financial barriers that could potentially hinder the successful adoption of RPA. Hence, to use RPA to its full potential, it is crucial to identify the potential barriers related to financial aspects in order to obtain sustainable value and gain a competitive advantage. The study has both academic and practical contributions as it allows managers or beef manufacturers to consider the financial risks when adopting RPA, and encourages improved financial decision-making when implementing RPA for process delivery. It further allows beef supply chains to conduct a critical and thorough cost analysis at different stages of the beef supply chain in order to alleviate or avoid any potential risks in the RPA adoption process and to achieve the sustainability goals. This will help organisations successfully adopt RPA in their supply chains and gain high productivity levels with low operational costs, thus creating sustainable value. The base of the research parameters used for the scenario analysis are costs associated with infrastructure/implementation expenses, and expenditures associated with different stages of beef supply chains. Two scenarios are analysed to observe the socio-economic impact of RPA implementation in beef supply chains and to investigate it from a sustainability perspective. The research parameters based on financial aspects are further examined in the results section.
The simulation and optimization of supply chain systems allows for analysing business processes using a virtual environment [
13]. The simulation approach is widely used in beef supply chains to assess the behaviours of processes at different stages of the supply chain. The assessment of behaviour of different events at various stages of the beef supply chain enables users to analyse and adopt the best strategy for conducting business activities. Furthermore, food manufacturers use simulation-based methods as a testing technique to analyse different events, processes, or activities at various stages across the supply chain. Food manufacturing supply chains are constantly under pressure due to perishable food items, which have a short life cycle and high production costs. Simulation techniques help to relieve the stress and pressure that food manufacturers face by identifying the bottlenecks and risks present in supply chain processes. This is of great help to the food manufacturing industry as the simulation approach ultimately helps to relieve financial tension and in aids smarter financial decision-making, thus reducing operational costs and increasing supply chain production or output [
14].
In supply chains, simulations imitate the operations of real-life scenarios or business systems with the utilization of models. The simulation method involves testing and analysing the business process model. The model represents the characteristics and key behaviours of a supply chain process or system procedure involving a chain of activities. Simulation-based optimization has its strengths and weaknesses in terms of process modelling and experimentation. While simulation has advantages, such as the behavioural assessment of business activities at different supply chain stages and the identification of potential risks in supply chain processes, the simulation method also has some limitations. Some of the prevailing limitations observed in simulation method are that it uses process modelling in a virtual environment, which can at times differ from real-world scenarios. Real-world situations involve humans; the human workforce behaves differently during times of disruption or panic in business situations or vulnerable environments. This is seen as a weakness or limitation in the simulation method, which can only assess or identify business or activity-bound risks, but it cannot evaluate human behaviour or reactions in difficult practical scenarios. Another simulation limitation could be associated with the cost of simulations, which could be high depending on the frequency of testing of the model. At times, due to data unavailability or the high cost of data accessibility, using the simulation method could become challenging. Simulations provide ways of evaluating and assessing solutions; however, simulations do not generate solutions themselves. Hence, the simulation method has no interference with real-world business systems. It allows business managers to visualize the long-term impacts in a quick and systematic manner [
15]. On the other hand, the simulation-based approach supports decision-makers by evaluating the potential risks and assessing business procedures and activities, which greatly helps managers or business users plan and schedule accordingly, as well as minimize or prevent the threshold of any risk events in real-life scenarios. In addition, with the wide use of virtual modelling and simulation techniques in manufacturing supply chains, people are also becoming familiar with virtual processes to prevent any risk events in the real world, combat aftershocks, and improve work-flow management systems. The simulation method and model optimization allow managers to understand and identify the impact of every action on the business process and to develop strategies to prevent any prevailing issues in advance [
16,
17].
There are various types of simulations present in supply chain management, such as system dynamics, business games, discrete-event simulation, and spreadsheet simulation [
18]. This study uses the discrete-event simulation technique as a simulation to map out different stages of the beef supply chain. The discrete-event simulation method is used to simulate the performance and behaviour of real-world processes, systems, or facilities. This simulation technique represents a discrete sequence or chain of events, or stages of a business system [
19,
20]. DES is a popular modelling method that is suitable for manufacturing systems as it provides insight into different processes or stages of a supply chain. The DES simulation method maps the different stages to observe the performance levels and behaviours of events or activities conducted through progressing time. The DES simulation technique has many advantages, such as providing a level of flexibility to the process by detailing and observing the dynamic behaviour of the supply chain at various stages. It is beneficial to use the DES modelling technique in manufacturing supply chains to analyse the performance levels of activities and to evaluate the operational efficiency of the supply chain. DES simulation also helps to identify the risks or uncertainties at various stages of the supply chain with respect to quality, logistics, efficiency, time taken, and interaction levels. This simulation technique is widely used within the food industry for quality assurance and productivity levels, but financial and operational efficiency remains challenging for food supply chains. The DES technique is used in practical aspects within food supply chains to determine the process performance and improve the standard of quality in food production [
21].
Other key advantages of the DES simulation include a thorough analysis of the operational efficiency levels within manufacturing supply chains, helping businesses save time, cost, and energy by determining risks and uncertainties. The operational efficiency can be evaluated by providing various resource inputs and parameters for robust results. The DES simulation technique, when used in practice, helps manufacturing supply chains understand and evaluate key risks that can be eliminated in real-life scenarios in order to boost process delivery and to lower operational costs to achieve sustainability. It further supports businesses with effective decision-making to enhance supply chain performance by reducing supply chain complexity and incorporating sustainable practices [
22].
As discussed above, in this study, the discrete-event simulation technique is used for modelling and staging beef supply chain processes. A model adopted from a previous study is used to simulate and analyse different scenarios, considering the financial aspects of the adoption process. Financial or cost-related parameters are the basis for developing the scenarios used for process simulation and examination in this study. The discrete-event simulation tool is widely used by food supply chains as it helps map supply chain processes for an enhanced understanding of the business system and how processes are carried out. It is a streamlined process for mapping different supply chain stages that can provide insight into the business activities or events [
23]. The discrete-event modelling technique also provides insight into the cost analysis, which greatly helps in assessing the sustainability of supply chains [
24]. Therefore, it is beneficial to use the modelling technique to assess the beef supply chain from financial or economic aspects, and to evaluate cost reductions and profitability by implementing RPA technology. The simulation model helps to further evaluate the time taken for tasks at various stages of the beef supply chain and how the chosen RPA technology save costs while improving efficiency. The technique could potentially investigate the economic and social value from the perspective of sustainability. The RPA model could also be adopted by managers or business decision-makers considering the financial or cost-related aspects. It also helps with effective financial decision-making in real-life scenarios, where the beef sector can alleviate or avoid financial barriers or risks beforehand and adopt a better approach for RPA implementation.
Section 2 discusses the literature review and provides an in-depth explanation and insight into the following aspects of the beef supply chain: dynamics and challenges, the significance of achieving sustainability through adopting RPA, different dimensions for a more sustainable approach through RPA adoption, and a simulation-based using RPA integration considering the financial aspects.
Section 3 highlights the methodological choice of research.
Section 4 discusses the results related to the simulation and analysis of the process model using different scenarios based on financial parameters. It further illustrates the KPI values, income statements, and carbon emission reports by simulating scenarios using Simul8 simulation software.
Section 5 is the discussion section where the simulation results of the scenarios are critically discussed with respect to the three dimensions of sustainability: social, economic, and environmental.
Section 6 discusses the conclusion, limitations, and future scope for research.
4. Results Based on Process Simulation
To obtain results regarding the adoption process, it is necessary to derive statistics and information related to financial aspects of the beef supply chain and RPA technology. This study used the available secondary data using online published sources, relevant literature, organisational websites, etc., focussed on adopting RPA technology as a sustainable tool for value creation in the beef supply chain, as well as the significance of RPA in beef supply chain management to create sustainable value. Several parameters influencing the adoption process of RPA technology were considered. This study focused on specific financial aspects concerning the adoption of RPA. We adopted existing financial statistical data and cost-related information regarding beef supply chain procedures and stages, beef supply chain management, RPA adoption criteria, installation costs, and other financial aspects of the beef supply chain that influence the implementation and facilitation of RPA. The financial parameters considered were significant for determining and investigating the role of RPA in order to enhance the financial performance and business operations within the beef sector, and to allow for the identification of any financial risks or barriers that could hinder its adoption. Moreover, financial parameters are vital to consider for the robust and successful adoption of RPA in order to add sustainable value within beef supply chains. RPA, as an important sustainability tool and innovative strategy, facilitates beef supply chains by reducing operational costs at different stages and enhances productivity, efficiency, and the capacity to satisfy the growing demand for beef. Reducing the processing costs of beef with the goal of achieving higher output levels remains a focus for business owners. The consideration of financial parameters not only assists in the smooth and robust adoption of RPA, but also allows the technology to become a game changer and act as a tool to add sustainability.
A simulation-based approach was chosen to assess the previously formed process model; it was tested using two scenarios based on financial parameters. The simulation using scenarios based on financial parameters was conducted using Simul8 simulation software. The simulation software used resource inputs and different stages of the beef supply chain were mapped using the DES modelling technique. The simulation tested the process model in order to generate income statements and financial KPIs, which determined the financial and operational performance of the beef supply chain. Variations in the resource input and costs were considered to ensure a thorough simulation test and run trial. Two resource inputs, namely labour and humans or RPA technology, were used in the process model.
The next stage of analysis assessed and evaluated the contextual relationship of the financial factors or parameters when adopting RPA in the beef supply chain. It is important to analyse the relationship between the financial factors that influence and impact the adoption of RPA in the beef supply chain. Hence, cost-related information and aspects at various stages of beef manufacturing and processing were a significant part of the analysis. Literature focusing on beef supply chain characteristics, manufacturing stages, financial aspects, and sustainability challenges were used to form a relationship model.
Figure 4 depicts the financial factors that play a vital role in the successful adoption of RPA technology in the beef supply chain. These factors are important to evaluate as they impact the implementation of RPA, as well as its potential advantages by easing process delivery, reducing operational costs, enhancing beef quality, and improving productivity to gain sustainable value.
Figure 4 shows the relationship between the financial factors that help create value and sustainability in the beef supply chain processes and impact the financial performance, business viability, and scalability in beef production. The financial factors or parameters depicted in the relationship model in
Figure 4 are fixed costs, direct or in-direct costs, and variable costs when implementing RPA in beef supply chains.
4.1. Process Model and Simulation Analysis—Financial Parameters as a Basis
A business process model formed in a previous study [
68] was used in this paper for the simulation. The present study focused on a specific direction for the scenario analysis based on financial aspects or parameters that has not been discussed in previous research; this is an important dimension to consider when adopting RPA in beef supply chains. The process model is comprised of different stages of the beef supply chain, providing insight into the supply chain processes. The process model shows the overall important stages of the beef manufacturing supply chain, from the processing and production of beef to the consumption by the customer. Financial aspects and cost-related statistics were considered for all stages of the business processes in order to investigate the economic status and financial health of the supply chain with and without the implementation of RPA technology. The economic performance of the supply chain is an important part of the analysis as it depends on beef productivity, profits, and business scalability and viability. Other aspects such as beef quality, safety, and capacity were also investigated using Simul8 simulation software.
Figure 5 shows the process model adopted in this study considering different cost-related parameters; three dimensions, social, economic, and environmental, were observed from a sustainability perspective.
The formed previously process model was simulated and analysed here using two different scenarios, where different resource inputs were used for testing. The two resource inputs were human workforce, which was used alone in Scenario 1. Scenario 2 analysed the human workforce working alongside RPA technology. The process model was tested, simulated, and run for 1 week in order to achieve more accurate results. The simulation was run at several frequencies to ensure robust results. The simulation was run several times using different financial parameters; these were the basis for the scenarios developed.
This discrete event simulation model used a simulation-based approach to investigate the changes in the financial and operational performance of the supply chain by providing various cost-related parameters. The simulation used resource inputs and other data based on financial aspects to observe the business performance at different stages of the supply chain [
69]. A simulation-based approach imitates a situation, circumstance, process, or operation so as to evaluate the risks or barriers in a supply chain system [
70]. The simulation technique helps stakeholders and business users test the supply chain activities and performance level in a virtual environment and provides organisations an opportunity to avoid these barriers in real-life situations. It also helps food manufacturers enhance their financial performance and produce food products of a high value and quality. By considering financial aspects using the simulation technique, food manufacturers can enhance their financial decision-making and increase productivity levels [
71].
4.1.1. Scenario 1—Financial Considerations Using the Human Workforce as a Resource
The process model simulated in Scenario 1 used a manual-centric supply chain and only the human workforce was throughout the various stages of the beef supply chain. The model was tested and run for 1 week (7 days (12 h per day)); it was replicated several times to record and evaluate the results with increased accuracy. The repeated runs in Simul8 used financial data and information to assess and evaluate the financial performance and operational efficiency of the business activities. The average time taken for the carcass to reach the end customer phase was also analysed using the simulation model. Based on the assumed scenario, the results showed the performance of humans in the manufacturing line and evaluated the queuing time for the carcass to reach the next phase in the supply chain.
Figure 6 shows the simulated process model that used labour or human workforce as the only resource input to perform the tasks. It was observed that beef capacity decreased as the stages progressed over time. It took longer for the carcass to reach to the progressing stage and the supply chain became slower. The overall productivity of beef production was also reduced at every stage of the supply chain; this means there was high human-error and wastage of beef along the processing line. The initial capacity seen at the start of the stunning and slaughtering stage was 40; this was reduced to 36 in the cutting and boning stage. The beef capacity was further reduced in the beef processing and packaging phase, with a value of 34. It dropped to 10 upon reaching the retailer or distribution centre, after which far less beef was produced for the final phase when reaching the customer. In this scenario, human efficiency was seen to be low and the operational efficiency was also evidently very low, with a low beef production capacity at the end. To further analyse the simulated model, as more time was taken when humans performed and conducted business activities at different stages of the supply chain, the costs for performing the activities on the processing line also increased, thus reducing the financial performance of the supply chain (
Figure 6). As depicted in
Figure 6, the main bottlenecks and risks were seen in the following phases: cutting and boning, beef processing and packaging, and retail.
The simulated process model also generated financial KPIs to provide insight regarding the working performance of the beef supply chain. Financial KPIs are key performance indicators that summarise the overall performance level; this is assessed by testing and running the process model in the software.
Table 3 depicts the analysis of the simulation process and the financial KPIs generated in Simul8. The average waiting time for carcass processing from the first stage to the last one was approximately 1428.76 min–23.81 h. The working% of the beef processing and packaging phase was 37.15; this appears to be low. The queue for the beef processing and packaging phase was an average size of 20.40. The average queuing time in this was noted to 253.50 min–4.2 h in the processing phase and the maximum queue time was observed to be 295.04–4.9 h, as illustrated in
Table 3. The simulation analysis showed an increase in the average time taken for the carcass to reach the end customer stage; the queuing size and time were also high, which decreased the processing line and increased the cost of production. The increase in time taken reduced the financial and operational efficiency of the supply chain and increased the likelihood of beef wastage and the production of low-quality beef due to increased human error. We further considered the challenges in the supply chain relating to social, economic, and environmental hazards from a sustainability perspective through values generated in
Table 3. These results indicate an increase in supply chain risks and disruptions and an increase in queuing size and time throughout the different stages.
To assess the overall financial performance of Scenario 1 for the manual-centric supply chain using the human workforce as a resource to complete task delivery, the software generated an income statement for the simulation. Simul8 provides an income statement, which helps business decision-makers decide whether the supply chain performance will generate profits or losses by assessing the costs and revenues at different stages of the supply chain. The secondary data and statistical information helped to assess the scenario using the human workforce to perform complex business procedures in the supply chain.
Figure 7 shows the income statement, which had a poor financial and operational performance (as also seen in
Table 3) as the costs were excessive due to increased human error as a result of the supply chain being manually driven for task completion. The income statement shows that the profit reached a negative value, indicating that the financial performance was low and the business activity costs were high, resulting in financial loss in the beef production. The average time taken from beef production until reaching the final customer was long and the supply chain lagged in efficiency and productivity. This was because of the higher average queuing size of 20.40 and increased average time in the beef processing and packaging stage, which was 253.30 min (4.3 h). Beef possessing cost 309,198.59 GBP and the revenue was only 24,700 GBP; this resulted in a negative number with a loss of −284,498.59 GBP. The generated income statement shows that because of the low financial and operational performance, Scenario 1 was unable to make a profit due to the slow processing line and high human error, and it did not achieve sustainable social, economic, and environmental value.
Figure 6 shows the low beef productivity and capacity at each progressing stage.
Figure 7 shows the high operational costs and increased energy and time consumption, which resulted in low production in the final stage; hence, the high demand for beef was not satisfied in this scenario. The supply chain costs exceeded the revenue, resulting in a poor financial performance and loss for the business in the assumed scenario analysis, as shown in the income statement report in
Figure 7.
Furthermore, Simul8 also generated a carbon emission report for Scenario 1. As shown in
Figure 8, the carbon emission report depicted the values related to emissions for each phase and activity of the supply chain. The carbon features from this report were broken down in order to analyse the values for emissions from each level. The carbon emissions for each stage of the beef life cycle in the supply chain were as a result of the energy use, fuel, packaging, extraction and use of raw materials, distribution, etc. The carbon emission report depicted the environmental impact caused during beef processing and manufacturing. As shown in the report in
Figure 8, the environmental impact through carbon emissions was 278,961.49 CO2e in Scenario 1, which was very high as the supply chain was manual-centric. The increased amount of carbon emissions at different phases of the supply chain and the lower value of carbon offset resulted in a high environmental impact, showing a high risk of air pollution, low quality beef production, and health threats to workers. There was also increased risk of beef contamination due to poor air quality and other environmental hazards. The carbon offset refers to removal or reduction of carbon emissions or other gases, and was observed to be 24,700.00 CO2e (
Figure 8), which was low.
4.1.2. Scenario 2—Financial Parameters as a Basis using RPA Integration with Humans as a Resource
Scenario 2 used two resource inputs at different workstations where RPA functioned alongside the human workforce to ease supply chain processes and automate tasks where RPA performed best. Scenario 2 considered the adoption of RPA technology to accelerate time taken, reduce human error, and increase throughput. This scenario integrated RPA along with humans to automate rule-based, repetitive tasks, and to provide autonomous solutions to create supply chain resilience. As seen in
Figure 9, the simulation was conducted over 1 week (7 days) and testing was conducted through several replications in order to achieve the appropriate simulation results. The scenario showed that the implementation of RPA to automate tasks was productive and efficient. The beef capacity remained more consistent in this scenario and was observed to increase at each progressing phase. The beef capacity in the stunning and slaughtering stage was 15 and reached 18 in the cutting and boning phase and 19 in the beef processing phase. The beef capacity increased to 35 in the retailer and distribution stage, where it was observed to be at its maximum. As time increased, the capacity of beef produced also increased in every stage, which resulted in higher beef production and availability at the end customer phase. This scenario took less time to produce high-quality beef with reduced human error and wastage along the processing line, as seen in
Figure 9. It also indicated a better financial performance as a result of the fast-paced processing line and greater beef production capacity.
Simul8 software also generated KPI values based on process simulation and provided a report to analyse the functional performance of the beef supply chain.
Table 4 shows the KPI values, which were used to evaluate the operational and financial performance of business activities using financial parameters that influence the adoption process of RPA in the beef supply chain. The average time for the final customer phase was 705.91 min–11.7 h, which was much less than the results for Scenario 1. This means that the carcass took 11.7 h to reach to the end customer phase. The working percentage of the beef processing and packaging was 90.87%, which was double the working% in Scenario 1. The average queue size was 17.75 at the beef processing and packaging stage, and the average queuing time was 181.84 min to 3 h. The maximum queuing time as per the KPI values was 370.13 min to 6 h. The KPI report indicates that the average time taken for the carcass to reach the end customer was much less than for Scenario 1; also, the working% was almost double in this case, meaning that the processing line was more efficient and faster. The average queuing time was also observed to be less than for Scenario 1. The KPI values indicated that automation enhanced business processes, resulting in increased beef production in decreased time and cost.
Furthermore, the simulation software also generated an income statement based on the simulation runs conducted.
Figure 10 displays the income statement showing the financial performance of the beef supply chain. The income statement from Simul8 was used to better analyse and evaluate the supply chain costs and revenue according to the resource inputs and cost-related parameters from the simulation runs. This scenario used RPA integration to automate tasks where possible and used suitable and manual workforce to aid through monitory purposes or for support with tasks that could not be fully automated due to the complexity of the beef supply chain. The income statement showed a good financial performance and effective function of the business activities as it indicated profits earned through the adoption of RPA, which served to facilitate strenuous tasks by reducing human error, thus reducing operational costs (as seen in
Figure 10). The revenue in the final customer phase was greater than the costs of performing business activities throughout all phases; therefore, the supply chain provided profits of 221, 300.39 GBP. The costs of beef production was 2,198,699.61 GBP in total and the revenue in the final stage was 2,420,000 GBP. Here, RPA showed promising cost-reduction benefits for supply chain processes by providing autonomous solutions and enhancing operational efficiency in the processing line. Less time was taken due to the reduced queue size and average time for carcass processing, which helped by reducing expenses and energy and provided an effective financial performance by earning profit, as displayed in the income statement generated by Simul8 in
Figure 10.
The simulation-based approach in Scenario 2 also provided an opportunity to assess the environmental impact of business activities during beef processing and manufacturing. Simul8 also produced a carbon emission report, as depicted in
Figure 11, to analyse the impact of RPA and humans working together in the processing line to perform various tasks. The carbon emission report generated by Simul8 software through the simulation indicated that the environmental impact of Scenario 2 was 141,082.49 CO2e. The carbon emissions was 165,182.49 CO2e and the carbon offset was 24,100.00 CO2e. As assessed from the report in
Figure 11, Scenario 2 had a much lower environmental impact than Scenario 1. The environmental impact of Scenario 2 was lower; however, it still had an impact on the environment because the supply chain was not yet fully automated as there were some complex procedures that still required human presence. As the environmental impact was not high and was measured as low, there were lower risks to human health and the environment in this scenario. In addition, these was a higher chance of high-quality beef production as the processing line was fast-paced due to the adoption of RPA and process excellence. Furthermore, the risk of disease transmission, beef contamination, and beef wastage along the processing line were minimal due to the lower environmental impact as evaluated and revealed in the report. Therefore, through the simulation assessment and carbon emission report in
Figure 11, Scenario 2 showed a lower environmental impact and safer, high-quality beef production.
6. Conclusions, Limitations, and Future Scope for Research
RPA can assist by streamlining business processes and providing sustainable business solutions by automating tasks and identifying risks [
76]. This study uses a simulation-based approach to conduct a sustainability assessment using the Simul8 software. The testing scenarios provide insight at important supply chain phases related to the cost analysis, along with a critical evaluation of the processes impacting on the environment, society, and economy. With various financial factors affecting the implementation and introductory process of RPA in beef supply chains, this study serves as a contribution towards the financial considerations for the adoption of RPA. No formal financial evaluation criteria have been explored for RPA adoption within the beef sector before. Beef supply chains are highly fragmented, making the adoption process of RPA more strategic and challenging; hence, it is crucial to consider the financial aspects of its application.
This study analyses the best approach for the RPA adoption process considering the significant financial factors in its implementation. The findings of the study are beneficial in both theoretical and practical aspects. It contributes to theoretical knowledge in academia by identifying potential financial risks and challenges faced by beef supply chains in the adoption of RPA. Moreover, it serves in practical aspects by providing a critical analysis on the cost-related factors that influence RPA application in beef supply chains. It also improves the RPA adoption process by considering financial aspects and provides a process model that can be utilized to enhance the financial decision-making of business owners. Additionally, the analysis of the results provides an opportunity to conduct a sustainability assessment based on the three dimensions, namely, social, economic, and environmental aspects. The sustainability assessment is achieved through the development, simulation, and testing of the assumed scenarios, offering new scientific knowledge that is beneficial for both academia and the beef industry. The sustainable value of both scenarios is evaluated through process simulation to establish which scenario experiences greater financial and operational efficiency. As discussed in the results and depicted in the KPI values, income statements, and carbon emission reports, Scenario 2 achieved sustainable value in the social, economic, and environmental aspects. Scenario 2 displayed process excellence, hygienic beef production, high productivity and capacity, reduced operational costs, and long-term business profits and viability in comparison with Scenario 1, which showed a poor financial and operational performance. The impact and influence of RPA is found to act as a cost-saver and sustainability driver in Scenario 2. RPA integration reduces human error, energy, and time, resulting in less risk of beef contamination, wastage, or pollution, thus making it environmentally friendly. The cost−benefit analysis in Scenario 2 shows that automation reduces costs, and resources are utilized better to enhance the supply chain production and financial performance.
The paper is original in its contribution to both theoretical and practical aspects through the provision of the process model as a business solution for robust RPA adoption in beef supply chains. It further adds to scientific knowledge through the identification of financial risks and barriers at different beef supply chain stages. The study benefits and supports mangers and stakeholders in the beef industry by providing a business process model that could be adopted and modified according to the needs and financial circumstances of business users. Moreover, it encourages business professionals in the beef industry to adopt RPA through the successful removal of financial risks by conducting a thorough cost analysis. The process model supports professional practice as utilizing RPA eliminates any potential barriers beforehand. Moreover, the study adds to the research by identifying the main bottlenecks in different and complex stages throughout the beef supply chain and highlights the socio-economic benefits of adopting RPA. Additionally, the paper supports academia as it assesses various scenarios and shows that the successful integration of RPA helps to reduce operational costs, time, and energy, while improving beef quality, efficiency, and business viability, and creates sustainable value through automated business processes. The successful adoption of RPA will allow beef manufacturing supply chains to improve work-flow business systems and enhance financial efficiency. This innovative technology acts as a tool for sustainability by boosting beef productivity and quality, as well as saving on high processing costs.
As explained above, this research paper contributions academically and practically to the beef sector, as well as assisting managers and practitioners in the beef industry. The study identifies the financial risks, bottlenecks, and barriers in the adoption of RPA, which has emerged as an important tool for sustainability tool and as driver within beef supply chains, thus contributing to scientific knowledge. The research paper focuses on the financial aspects that influence the adoption of RPA in order to enhance supply chain operations and increase business viability. The study is unique as it considers the importance of the financial parameters that contribute to the successful adoption of RPA in beef supply chains, something that has not been given attention in previous studies. The study also observes two scenarios through process simulation to evaluate the potential risks throughout different workstations within the beef supply chain system. The simulation-based approach tests and evaluates “what-if” scenarios, using financial parameters as a basis for the simulation analysis. In addition, it not only focuses on the identification of financial risks or barriers using values or variables, but also analyses the process model from the perspective of sustainability. The findings of the study are important for evaluating the sustainability of adopting RPA in beef supply chains, and further observe the impact of integrating RPA in terms of social, economic, and environmental aspects. The findings of the study generate KPI values, income statement reports, and carbon emission reports by assessing the scenario simulations using Simul8 software. The scenarios are assessed from the perspective of sustainability and added value to observe supply chain operational and financial performance with and without the adoption of RPA. The study contributes practically as it provides a business process model for managers and practitioners within the beef industry, and the model could be adopted and modified according to the financial conditions, requirements, and individual circumstances of the beef supply chains. The simulation analysis and process model provide the opportunity for beef manufacturers to perform a thorough cost analysis to adopt RPA technology using the best approach. Using scenario testing, the findings of the study further facilitate managers by enhancing their financial and ethical decision-making, as well as by gaining maximized benefits and opportunities through the successful implementation of RPA within beef supply chains.
This study is in a specific domain and has some limitations. The study is limited to RPA application in beef supply chains; other food supply chains need to be investigated separately to analyse the use of RPA as a tool for sustainability. Another possible limitation of the project is the limited availability of data related to beef supply chains as well as the integration of RPA; however, this can be addressed through by developing different scenarios in the simulation process, as explained and discussed before. The research is limited to using the discrete-event modelling technique as the simulation approach for the scenario assessment. Other modelling techniques can be explored in future works in this specific domain. This study uses Simul8 software for simulation analysis and scenario testing, and this could be seen as another limitation of the study.
The findings of the study highlight that adopting RPA reduces operational costs, lessens environmental impact, and enhances beef productivity and quality through task automation, which increases sustainability in beef supply chains. Future works in the field could potentially focus on the development of other simulation models based on other factors or parameters, such as logistics, RPA assistance, technical expertise, and RPA design, that influence the adoption of RPA. This study contributes to a specific field and focuses on beef supply chains, and advancements in work could also consider other meat supply chains that could also benefit from sustainability-oriented innovations such as RPA technology for process acceleration. Future studies could also potentially evaluate other socio-economic benefits through advanced simulation testing and analysation considering the organisational factors impacting the adoption of RPA. Future studies could concentrate on simulation models to provide further insight and additional methods to tackle the environmental hazards and emissions resulting from beef production using RPA facilitations and opportunities. Other modelling techniques and simulation software such as AnyLogic, MATLAB, and SimScale could be used for model development and sustainability assessment in order to observe different approaches to RPA adoption and to create sustainable value. Currently, there are no thorough evaluations on the integration of RPA with AI assessing intelligent process automation in beef supply chains, and future works could focus on this domain. Moreover, future approaches in this field could explore contextual factors, such as managerial, individual, and organisational parameters, in the adoption of RPA. There are also no extensive studies on suitable processes for automation; hence, future works could critically analyse automation suitability according to organisational set up and explore ways to achieve sustainable value and a competitive advantage.
