【摘要】 本文结合三峡工程混凝土运输的系统模拟,提出了从混凝土运输系统结构着手,建立状态转移模型,然后绘出计算机框图的分析方法。设计了包括汽车在混凝土拌和楼前排队;汽车运行不准超车;通过T型路口让车和绿灯时多辆车一次通过T型路口等功能的模拟程序。模拟结果比较符合实际情况。该法可供求解多级服务的循环排队问题。更多还原

【Abstract】 Simulation method for concrete transportation system in Three Gorges project is presented.It contains system structure,state transition matrix and block diagram.Simulation programs are designed,including queues at concrete mixing plants,no overtaking of loaded vehicles and waiting-line at T-junctions etc.This method provides a solution to cyclic queues composed of interconnected stages of service.更多还原
