摘要
对离散事件动态系统（ＤＥＤＳ）的仿真过程建立了包含中断事件集和驱动事件集的广义半马尔可夫过程（ＧＳＭＰ）模型，对参数的无穷小扰动所引起的系统状态转移时刻进行了扰动分析．最后，讨论了扰动分析所需要的可交换条件和样本性能函数的关系。
A Generalized Semi Markov Process (GSMP) model,which is described through interrupted events set and triggering events set,is established for simulation in Discrete Event Dynamic Systems (DEDS).Gradient estimator for a class of system performance measure is also obtained by Perturbation Analysis (PA) for epochs of state transition corresponding to infinitesimal perturbation in parameter.Finally,relation between commuting condition for PA and sample performance function is discussed and some open problems are pointed out.
