Comprehensive Decision-making for the Site Selection of Thermal Power Plants Based on Entropy TOPSIS

The main methods used in the comprehensive decision-making for the site selection of thermal power plants are dependent on experts' evaluation to determine index weight,which is subjective and difficult to ensure the correct understanding and the optimum use of scoring rules.In this paper,entropy TOPSIS method was used in the site selection of thermal power plants.This method used the entropy weight to calculate the weights for each index objectively.Meanwhile,it conducted the positive ideal and negative ideal solutions in order to choose the alternative which had the shortest distance from the positive one and the farthest distance from the negative one.Finally,after the establishment of the index system of the site selection of thermal power plants,an example was presented to show the application process of the site selection of thermal power plants based on entropy TOPSIS.Furthermore,the simulation results demonstrated the scientificity and feasibility of the approach.
