The Research Of Supply Chain Performance Evaluation System And Its Diagnosis Mechanism

Under the background of rapid development of the Internet and logistics environment, supply chain has become the main competition in today’s world. Quality, time, personalized requirements have become the key to product marketing. Supply chain management keeps pace with the times while facing more and more challenges. The performance evaluation of supply chain is an effective means of supply chain management. It can not only grasp the level of supply chain management, but also master failures of the supply chain. Then it’ll keep the supply chain steady, healthy and sustainable.Based on the study of the evaluation model, the evaluation index, the evaluation method about supply chain, we know that the evaluation index systems are different under different purposes. The overall supply chain performance evaluation index system is built under the goal of understanding the overall supply chain performance level, it’s established from five aspects of reliability, cost and profit, flexible, collaborative, learning and innovation. Further, to diagnose the fault of supply chain, a link supply chain performance evaluation index system is built. It makes forecast, plan, order, purchasing, production, transportation, distribution, sale, as the subsystem of supply chain. The indexes of subsystems are also established from the five aspects.Through the study of all kinds of neural network algorithm, BP neural network algorithm is considered as the evaluation method. A momentum factor is added to the algorithm to optimize the learning process. Under the computing environment of the Matlab, with the application of the improved BP neural network to diagnose the production performance of X motor company. In order to make the evaluation results more objective, they are subdivided into benchmarking+, benchmarking and benchmarking-grade and so on. Classify the four kind mechanisms of benchmarking, optimization, warning, and rejected based on the diagnosis.Diagnose the failure cause of supply chain system or subsystem by using failure mode and effects analysis method. The failure cause can be divided into commonness and particularity, and accordingly esta lish commonly repair decisions library and particularly repair decisions library. Then put forward the right repair decision according to the problem of X motor company.
