Attitude Index Group Decision-making Method of Performance Evaluation for Coal Enterprises Energy Conservation and Reduction of Pollutant Emissions
نویسندگان
چکیده
For the performance evaluation of coal enterprises energy conservation and reduction of pollutant emission, a new attitude index group decision-making method is proposed based on trapezoidal fuzzy numbers. Under the condition in which the information of attributes weights and decision maker weights is entirely, the attitude index is introduced firstly. By solving the fuzzy object programming for the entirely information, the weights of the attitude and decision making matrix are determined. Secondly, the value of group risk attitude is got by integrating the attitude index of the decision makers, and the group comprehensive attribute values of each alternative and the priorities are achieved. At last, the practical example of performance evaluation for coal enterprises energy conservation and reduction of pollutant emission shows the feasibility and effectiveness of the proposed method.
