Giving Structure and Weight to Sustainable and Green Production Indicators of Iranian Thermal Power Plants using Best-Worst Method

Performance evaluation is necessary for sustainable and green production of companies such as thermal power plants. Sustainability Balanced Scorecard (SBSC) is a common model in this area. Assumption in SBSC is perspectives/indicators/sub-indicators (elements) weight equality that may be problematic in real-world problems. In this paper, firstly a mathematical model was presented to calculate global weight of elements in hierarchical structure by Best-Worst Method (BWM). Then, four properties of the desirable practical structure of the elements were defined by getting idea from designing hierarchical structure concepts in the Analytic Hierarchy Process. Then, an algorithm was presented to design multi-level structure of problems elements and give weights to them using the proposed giving weight model, four properties of the desirable practical structure, and Consistency Ratio Thresholds. A four-level hierarchical structure including 50 identified performance evaluation elements of SBSC model was presented using the proposed algorithm for giving structure and weight to performance evaluation SBSC elements in Iranian thermal power plants according to green and sustainable production. Finally, by considering the elements used in the resulting structure, a suitable indicators list of Iranian thermal power plants according to green and sustainable production was derived. The findings indicate the suitability of the proposed algorithm.
