Coupling Two-Stage Stochastic Robust Programming with Improved Export Coefficient for Water Allocation among Industrial Sectors

Round 1

Reviewer 1 Report

The paper deals with the presentation of a water allocation optimisation approach among industrial sectors under uncertainty. An export coefficient coupled with two-stage stochastic robust programming method (EC-TSRP) was developed through integrating export coefficient model (ECM), two-stage stochastic programming (TSP) and robust optimization. 

The paper is generally well organised and easy to be read. The paper structure is clear and only minor issues can be found.

Two general issues require at least to be discussed in the paper:

• The economic costs of environmental damage should be evaluated. The approach is evaluating this aspect as the cost derived from the missed respect of environmental regulations. At least a discussion should be provided about the potential costs of environmental remediation (i.e. the environmental damage evaluated as the cost to remediate a polluted environment)
• Uncertainty should be quantified. I understand that uncertainty is introduced in terms of uncertain parameters and boundary conditions but the evaluation of potential impact of such uncertainties on the final results should be provided and discussed
• Conclusions are a little too long. I would suggest to slightly reduce the first part avoiding to summarise the research done

Reviewer 2 Report

 

 

Comments to the editors:

 

The authors developed an inexact two-stage stochastic robust programming coupling 2 with improved export coefficient for water allocation among in-3 dustrial sectors under uncertainty. The application is interesting and the prose in the paper is well-written. There is a good discussion of the inferences/implications of applying the model. I only have some minor concerns as indicated in the comments to the authors. I would suggest a minor revision.

 

 

Detailed Comments to the Authors:

 

1.   More details regarding the data collection and parameter (including the probability distribution) estimation should be given.

2.   In the dynamic process (two-stage) of water resource management in your study, what are specifically the two stages, and what are the variables in each stage?

3.   How is “possibilistic distribution” different from the “probability distribution” in your paper?

4.   Can you discuss how the EC-TSRP model would be applied to the other watersheds? What challenges would be encountered?

5.   There are some syntax or grammatical mistakes. I would recommend proofreading it once again carefully to correct them.
