Abstract：Aimming atthe discrete manufacturing workshop with the complex environment, variable processing tasks and the frequent occurrence of abnormal production, it is difficult for production logistics system to support the optimal operation of production lines and the efficient execution of tasks. Based on complex network theory, a method of modeling and performance analysis for the discrete manufacturing workshop production logistics system networkis proposed. Firstly, according to the operating characteristics of the typical discrete manufacturing workshop production logistics system,a dual-weighted directed network model of production logistics system with station and workshop warehouse as the node and material flow as the edge is constructed. and its dynamic evolution driving factors are analyzed. The performance indicators of the production logistics system network, such as node importance, stability and self-repair ability, are researched, which provides theoretical support for the optimization and stable operation of the discrete manufacturing workshop production logistics system. Finally, the effectiveness and applicability of the proposed method are verified by the production logistics system of an auto parts machine shop in Chongqing.
