Special Issue Information

Dear Colleagues,

To optimize and manage modern industrial systems as well as facilities, many factors must be taken into account. Modern technologies in all sectors of activity depend on large amounts of sensors and data that facilitate multivariable analyses via algorithms to support decision making in the short, middle, and long terms. Classical and deep learning machine models have boosted the capacity to analyze large volumes of data and extract patterns that greatly contribute to informed decisions, making intelligent systems more prevalent and an important part of all organizations.

Industries and large institutions are always concerned about adjusting capacity and minimizing costs, in order to meet demand without delays or the excessive use of resources. This drives research focusing on models that can provide consistent support in decision-making processes. Prediction techniques based on time series models and artificial intelligence are being used more frequently to meet these challenges and contribute to more informed decisions.

This Special Issue aims to cover the latest research so decisions made based on the proposed algorithms are sound and adequate and contribute to facilitate management as well as operational decisions. Original contributions on the above aspects, and related topics, are encouraged.

Machine learning (ML) techniques are increasingly used to diagnose faults in aerospace applications, but diagnosing multiple faults in aircraft fuel systems (AFSs) remains challenging due to complex component interactions. This paper evaluates the accuracy and introduces an innovative approach to quantify and compare the interpretability of four ML classification methods—artificial neural networks (ANNs), support vector machines (SVMs), decision trees (DTs), and logistic regressions (LRs)—for diagnosing fault combinations present in AFSs. While the ANN achieved the highest diagnostic accuracy at 90%, surpassing other methods, its interpretability was limited. By contrast, the decision tree model showed an 82% consistency between global explanations and engineering insights, highlighting its advantage in interpretability despite the lower accuracy. Interpretability was assessed using two widely accepted tools, LIME and SHAP, alongside engineering understanding. These findings underscore a trade-off between prediction accuracy and interpretability, which is critical for trust in ML applications in aerospace. Although an ANN can deliver high diagnostic accuracy, a decision tree offers more transparent results, facilitating better alignment with engineering expectations even at a slight cost to accuracy.
