Study on Comprehensive Evaluation of Supplier Selection in Equipment Competitive Development

This paper aims to give a comprehensive evaluation of equipment competitive development stage based on TOPSIS (Technique for Order Preference by Similarity to Solution) method and temporal operator. Competitive development of equipment is a new trend in the current national military-civilian integration strategy. In the past, the evaluation of equipment in the competitive development stage was mostly based on the historical information provided by suppliers, rather than on objective information. In the competitive development stage, equipment generally needs to do three major tests: Electromagnetic compatibility (EMC) test, environment test and reliability test. Therefore, experts can be used to objectively evaluate the test results. Then, the TOPSIS method and temporal operator are combined to process the evaluation information, and the comprehensive evaluation factor of the equipment is obtained by considering the cost of the equipment. Case study shows that the method has strong engineering practicability.
