摘要
目前的仿真研究不能适应公路施工周期长、影响因素多的特点.提出全过程仿真的概念,给出了全过程仿真的Petri网定义,研究了模型输出与模型参数、模型结构之间的关系以及模型自适应算法的实现方法.分析了全过程仿真系统设计的基本原则,建立了基于Petri网的分层全过程仿真系统,该系统使模型能够自动匹配工程状态,有效地解决了模型的有效性问题.最后以工程实例表明使用全过程仿真系统可以很好地为公路施工提供决策支持.
The current studies of simulation are not suitable for highway construction because of long period of time,multifactor impact,etc. A trans simulation is proposed to solve these problems in this paper. The definition of trans simulation in Petri nets is presented and the relationships between model outputs and model parameters, model structure, model adaptive algorithm are studied. For practical use, the hierarchy trans-simulation system is built based on some given principles. An example of earth moving is given to show that models in this system can match the construction state automatically and this system can ensure the validity of models and provides supports to highway construction decision.
