摘　　要：与流水线生产方式不同,门座起重机结构件制造及整机总装物流系统在生产制造过程中具有不连续特征。基于离散事件动态系统理论,分析了起重机制造过程中的不确定性因素,建立了其制造系统的概念模型,并结合某起重机结构件制造及整机总装基地,建立了其制造系统的仿真模型,最后进行了仿真试验研究,提出了改善生产效能的建议。Different from the flow line production,fabrication of structural members in the portal crane and general assembly and logistics system indicate discontinuity in the production process.Based on the dynamic system theory of dis-crete events,the paper analyzes uncertainty factors in the crane manufacturing,with the concept model for the manufactur-ing system built,and then the simulation model built considering fabrication of crane structural members and general as-sembly base.In the end,the simulation test research is done and suggestions for improvement of production efficiency are put forward.
