【摘要】 对信息不完全条件下的应急物资转运系统建立了一个随机Petri网模型。根据这一模型,找到了计算各个状态中驻留时间、卡车的平均利用率、物资分发点等待物资的平均等待概率、物资分发点等待物资的平均等待时间的方法。使用这个模型对某企业在汶川特大地震应急物资保障中的物资转运系统的性能进行了计算,性能计算的主要结果与实际统计数据吻合。更多还原

【Abstract】 The stochastic Petri Net with partial information in emergency material transfer system is modeled.In accordance with the model,the methods for the calculation of average sojourn time of various states,average utilization of the truck,and average waiting chances and time in the material distribution sites are found.Using this model,the performance of a material transfer system of an enterprise in the transportation of emergent materials in Wenchuan earthquake is calculated,and the main results of the performance calculation agree with actual statistics.更多还原
