Abstract: In view of the discrete manufacturing workshop with the complex production environment,variable processing tasks and frequent occurrence of abnormal production,it is difficult for production logistics 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 network was proposed.According to the operating characteristics of typical discrete manufacturing workshop production logistics system,a dual-weighted directed network model of production logistics system with time window was constructed,which took station and storage unit as nodes and material flow as edges.The dynamic evolution driving factors of the proposed model were analyzed.The performance indicators of production logistics network such as node importance,stability and self-repair ability were researched,which provided theoretical support for the optimization and stable operation of the discrete manufacturing workshop production logistics business.The effectiveness and applicability of the proposed method were verified by the production logistics business of engine cabinet machining shop in Chongqing.
