Optimal Selection of Complex Product Manufacturing Service Suppliers Based on Blockchain Technology

The rapid development of information technology is profoundly affecting the manufacturing industry. Compared to traditional manufacturing industry, the complex product manufacturing is of high complexity, and with large amount of manufacturing service suppliers, so complex product suppliers selection is of significant importance. This paper constructs a complex product manufacturing service suppliers selection model based on blockchain technology, providing a secure and efficient platform for information sharing and decision optimization. Moreover, a robust goal programming (RGP) method for selecting complex product manufacturing service suppliers under uncertain demand is proposed. Finally, the feasibility and effectiveness of the proposed method are verified through example.
