城市交通系统的建模与仿真

本文首先通过分析建模中常用的离散事件仿真算法,根据大系统理论的递阶思想,提出了一个适合大系统仿真的新算法——递阶仿真算法.然后,建立了一个较通用的交通系统仿真模型(UTSS 模型).经过模型有效性验证,证明该模型是可行的,具有实用价值.

A new simulation algorithm for large scale system simulation-hierarchical simu-lation algorithm is presented in this paper by means of analyzing a few general di-screte event simulation algorithms in modeling and follow the hierarchical idca ofthe large-scale system theory.Furthermore a more general simulation model of urbantraffic system is established by this hierarchical simulation algorithm(i.e UTSS).This model has been validated and the result shows that the model is feasible andvaluable for practical usage.
