# An integrated three-way decision methodology for sustainability of wastewater circularity in thermal power plants

## Description

These Microsoft Excel files support our manuscript titled “An integrated three-way decision methodology for sustainability of wastewater circularity in thermal power plants”. 1. We include the file for our dataset of 11 expert decision-makers. This file is necessary for the application of our proposed 3WD-MARCOS method. 2. We include the computations of our Example 1 until Example 4. 3. We also include a file that presents our data for the best-worst method. The results from Lingo® optimization software are shown in this file. We detailed here the computations necessary in obtaining the attribute weights. This file supports Table 5 of our manuscript. 4. We attach here the file for the 3WD-MARCOS application of our case study. This file supports Table 8 and Table 9 of our manuscript. 5. We include the necessary computations of our sensitivity analysis, shown in Section 5 of our manuscript. This file supports Figure 3. 6. Finally, we include a file showing the computations of our comparative analysis (Section 5). This file supports Figure 4, Figure 5, and Table 10 of our manuscript.

## Steps to reproduce

These are the steps to reproduce: 1. You need access to our paper titled “An integrated three-way decision methodology for sustainability of wastewater circularity in thermal power plants”. 2. Proceed to Section 2.2. of the manuscript. The computations of Example 1 are shown in a worksheet within the data file “Computations_Examples 1-4.xlsx”. Make sure you keep track of the equations. 3. Proceed to Section 3 of the manuscript. The computations in Example 2 to Example 4 are shown in a worksheet in the “Computations_Examples 1-4.xlsx" data file. Make sure you keep track of the equations. 4. Proceed to Section 2.1. of the manuscript, which details the best-worst method. Following Step 3 of Section 4.2., implement Equation (2) to each respondent in the data file “Computations_Attribute Weights_Best-Worst Method.xlsx”. The aggregation and normalization to obtain the final attribute weights are shown in a worksheet within the file. 5. With the data file “Dataset_Decision Matrices from Expert Decision-Makers.xlsx”, implement Step 4 until Step 9 of Section 4.2. Ensure you keep track of the corresponding equations to follow through the computational steps outlined in the data file “Computations_3WD-MARCOS Application.xlsx”. The ranking of the alternatives (i.e., wastewater reuse applications) can be found in a worksheet within the data file. 6. Proceed to Section 5 to generate insights regarding the sensitivity analysis. Each worksheet in the data file “Computations_Sensitivity Analysis_Section 5.xlsx” corresponds to the combination of weights assigned to the expert and non-expert groups. The summary of the results that generate Figure 3 can be found in a worksheet within the file. 7. Proceed again to Section 5 to generate insights regarding the comparative analysis. With the help of the data file “Dataset_Decision Matrices from Expert Decision-Makers.xlsx”, implement the algorithms of identified methods. Each worksheet corresponds to a specific application of a method. The summary of the results that yield Figure 4, Figure 5, and Table 10 can be found in a worksheet within the file.
