本文对离散型封闭式传送带生产系统给出了一种通用的分析方法.基于传送带参数和工作站的服务时间,研究了系统中各流量间的相互关系,建立了动态的和稳态的表达式,给出了系统的品质指标,并首次指出了系统中存在一种循环效应及其对系统容量的影响。最后用仿真方法检验了分析结果的正确性. In this paper, a general analysis method is given for the discrete closed conveyor belt production system.Based on the parameters of the conveyor belt and the service time of the workstation, the relationship between the flow rates in the system is studied and the dynamic and steady- The system quality index is given, and for the first time it is pointed out that there is a circulation effect in the system and its impact on system capacity. Finally, the simulation results verify the correctness of the results.
