The Application of TOPSIS in Seeking an Optimum Method of Blended Coal

This article mainly introduces the method of TOPSIS and describes in much detail the application of TOPSIS in seeking the optimum method of blended coal by confirming the weight of index with entropy. A blended coal combustion in power plant issue as an example, optimum method is selected under the condition that four aims and four kinds of blended coals. The method can combine qualitative analysis with quantitative analysis effectively, synthesize evaluating information of each index adequately, which provides a good way for the optimization of blended coals.
