Solving a Multiple User Energy Source Selection Problem Using a Fuzzy Multi-Criteria Group Decision-Making Approach

In recent years, the evaluation of several energy sources is an extremely significant issue that affects socio-environmental development and techno-economic growth in different sectors. To tackle this concern, many researchers have concentrated on preferring desirable adopting multi-criteria group decision-making (MCGDM) approaches for only a single type user (e.g., agricultural, industrial, tourism, or domestic users). However, every plays important role shaping policy. fact, sustainable energy, it to include all main users at same time decision-making. The objective work was propose fuzzy MCGDM approach evaluate prioritize Tunisia from various sectors’ point views. Many criteria are combined, including following: technical, economic, social, political environmental. After applying Delphi method, proposed consists TOPSIS method as approach. Finally, sensitivity analysis performed results study how optimal solution affected by function coefficients.
