Supply Chain Management Optimization of Small and Micro Enterprises in Circulation Industry based on Information System and GPS

Due to the increasingly fierce market competition, enterprises are committed to shorten the supply chain cycle to increase the competitiveness of the supply chain. Supply chain cycle includes product development cycle, procurement cycle and transportation cycle. Enterprises need to speed up the rapid flow of logistics, information flow and capital flow. In this paper, the result of single point positioning is filtered by Kalman filter, which is used as a higher precision floating-point solution. Compared with the traditional methods, the algorithm proposed in this paper significantly improves the positioning accuracy and meets the needs of practical application.
