Coal suppliers evaluation model based on AHP and PROMETHEE

Abstract

Abstract:The coal suppliers evaluation and selection is significant for thermal power plants to reduce the cost of power generation and enhance market competitiveness. After analyzing the limitations of the existing multiple criteria decision methods, a method for coal suppliers selection is developed by integrating analytic hierarchy process (AHP) and preference ranking organization methods for enrichment evaluations (PROMETHEE). In the process of actual evaluation, satisfaction of alternatives is the same but index value of various alternatives is different. In order to solve this problem the paper puts forward a data preprocessing method. AHP is used to analyze the structure of coal supplier selection and determine weights for evaluation criteria, and PROMETHEE is used for final raking. Finally, a numerical example is given to illustrate the efficiency of the proposed model.
