摘要
Petri网络模拟方法是通过应用Petri网的基本特性对施工系统进行建模,描述模型中资源等施工参数随施工进度的变化,其网络模型能够较好地描述实际施工系统的动态变化情况,优选施工组织方案和施工机械设备的配置。本文系统分析隧洞施工过程及其程序,建立了基于Petri网络的施工过程模拟模型以及可行施工方案的多目标决策模型。实例分析说明了模拟方法、模拟模型和决策模型是有效的、可行的。
Based on the characteristics of Perti net, the simulation models of construction system are established. They describe relationships between the parameters, schedule and dynamic changes of the real construction system, and optimize the schemes and machine numbers of construction process. Then, a tunnel construction process and procedure are systematically analyzed. Finally, a multi-objective decision mathematical model is developed for construction planning. A case study illustrates that the simulation method and models are reasonable and effective.
