摘要
本文通过对一类离散事件动态系统——拆卸生产线的建模,介绍了一种新的概率建模方法——概率流方法.所谓“概率流”是状态间转移概率的一种形象描述,概率流建模的出发点是充分小时间内状态转移概率的流平衡,所得到模型是非线性方程组形式,通过定性分析可证系统是渐近稳定的.此外,本文还讨论了概率流方法与马氏理论的联系与区别.
A new probabilistic modelling method—probabilistic flow method,is presented by modelling a kindof discrete event dynamic system—disamounting line.‘Probabilistic flow’is a figurative description oftransferring probability among states.Probabilistie modelling is based on the‘flow’balance within thetime short enough,and the model is obtained in form of nonlinear equations which can be proved to beasymptotically steady.Linkage and distinguishment between probabilistic flow method and Markov theo-ry are also discussed.
