Supplier Selection Evaluation of Shipbuilding Enterprises Based on Entropy Weight and Multi-attribute Decision Making

The healthy and stable development of the shipbuilding industry has played a significant role in promoting the national economy. China is now in a critical period of transition from a big shipbuilding industry into a powerful shipbuilding industry in which the competition in shipbuilding industry is becoming increasingly fierce. Ship enterprises should not rely solely on subjective factors to make decisions. And they should set up a perfect scientific evaluation system to conduct a comprehensive and specific evaluation of suppliers which is also the key to promote the development of ship supply chain management. In this paper, we take ship enterprise supplier selection evaluation as the research object, and propose an evaluation model based on entropy weight. Firstly, considering the external environment of an enterprise, we adopt the method of combining literature research and field investigation to establish the evaluation index system of supplier selection of shipbuilding enterprises. Then we use a comprehensive and synthetic evaluation method of improved AHP, the improved entropy weight coefficient method and the TOPSIS method to evaluate the weights of each evaluation index. So we conclude that supplier selection membership size relationship to determine which supply is the best supplier. Finally, we take a ship enterprise supplier selection evaluation as an analysis case, and conclude that S3 is the best supplier. The research shows that the evaluation method is scientific and easy to operate, and it has certain popularization and application value in solving the problem of supplier selection of ship enterprises.
