摘　　要：在随机环境虚拟构建基础上,提出了基于马氏随机过程的时变移动对象行为仿真模型构建方法。针对随机路径网、移动对象速度可变、路径选择随机的复杂随机行为建立了新模型,在分析移动对象运动方程和时间采集关系的基础上,模型可以良好实现移动对象在二维路径网上的马氏随机游动过程。仿真数据结果表明,新模型能够正确地反映移动对象的随机变化,同时对移动对象运动轨迹和时间采集是有效的。The model of moving object action simulation was considered based on Markov random processes under virtual stochastic environment. The new model of complex stochastic behavior which the routes network and the choice of routes are random, the speed of moving objects is variable, was set up. With the analysis for motion equation of moving objects and collection of time, the Markov random walk on two-dimensional routes network well by the model was realized. Results of the experiments show that not only the random change of moving objects can be reflected exactly, but also the trajectories of moving objects and collection of time is effectively.
