公路施工仿真模型自适应算法研究

针对公路施工过程周期长、参与主体多、施工方法多变等特点,提出在公路施工中进行全过程仿真的应用需求,全过程仿真的核心内容便是模型的自适应算法.在Petri网的数学分析方法基础上,使用数学分析的方法建立了模型输出和参数之间的关系,推导出模型生产率的表达式、变迁相关度的定义和计算公式以及模型时间参数调整的公式,最后给出了自适应算法流程.

Study on simulation model self-match algorithm in highway construction

For the characteristics of long-term, widely-involved, methods-various in highway construction, the application demand of the trans-simulation in highway construction process is proposed. The core of the trans-simulation is model self-match algorithm. Based on the algebraic analysis methods of Petri nets,the relation between output and parameters of models is built, the model productivity expression, the definition of relative-degree of transitions as well as its calculation formula, the model time parameters adjustment formula are deduced, the flow chart of the self-match algorithm is summarized.
