Coordination performance evaluation of supply logistics in JIT environment

In JIT assembly system, any supplier's postponement of delivery or incorrect delivery quantity will result in the manufacturer's incapability of assembling on schedule, which will not only damage the interests of other suppliers but also jeopardize the interests of enterprises and reduce the competitiveness of the supply chain. In this article, coordination of the upstream supply logistics from internal and external aspects is taken as the research object. In external supply system, three aspects of cost, quality and time are used to evaluate the coordination of supply logistics in JIT environment. From the internal aspect, reliability, flexibility, responsiveness, customer service and system suitability are selected for the performance evaluation. The eight indexes construct an index system and each performance index is described and analyzed. Finally, Analytic Hierarchy Process is used to evaluate the coordinated performance of supply logistics in JIT environment. An example is provided, which illustrate the method used in this paper is feasible and meaningful.
