Application of the TOPSIS Based on Entropy-AHP Weight in Nuclear Power Plant Nuclear-Grade Equipment Supplier Selection

Nuclear power plants (NPPs) has their special characteristics, which both on product safety and on the life cycle of supplier, thus evaluation and selection of the equipment supplier requires independent evaluation index system, based on establishing an evaluation index system, an framework is proposed to address the supplier selection problem in NPP application of improved technique for order preference by similarity to ideal solution (TOPSIS) weighted by analytical hierarchy process (AHP) and entropy value, where it calculates all the indexespsila weights and the distances between the supplier and the ideal solution to find each supplierspsila closeness coefficient. Then the ranking of the suppliers are determined according to their results. Finally, for application and verification, an empirical study is performed to demonstrate the integrated model and identify the suitable supplier(s).
