摘　　要：运输系统的规划直接影响施工进度的实现和工程建设的成败。本文利用Petri网适合于描述系统组织、结构和状态的变化及面向对象仿真技术易于构造相互作用的现实系统模型的特点,建立了赋时Petri网的三峡三期截流施工运输系统模型,并将面向对象技术溶入Petri网。运用仿真模型及方法优选施工机械设备的配置,较好地反映了施工系统状态的动态变化情况。计算与分析结果表明该仿真模型及方法是有效的、可行的。The layout of a transportation system influences the construction schedule and project success-failure directly. Based on that Petri nets are fit to describe transformations of the system form and state and that object-oriented technology is easy to construct interactive system, this paper establishes the model of Ⅲ-Phase Closure of TGP for transportation system using timed-Petri nets combined with object-oriented technology. The exertion of this simulation model and method optimizes the machine numbers of construction process and reflects transformations of the system state. The computational results illustrate that the simulation model and method are effective and feasible.
