| 摘 要： | 借助于无穷小矩阵摄动方法, 讨论了一类Markov过程, 其稳态性能关于参数摄动的灵敏度分析问题. 然后研究了闭排队网络的稳态性能灵敏度分析问题, 并在参数相关性能函数的情况下, 给出了网络的几种稳态性能的灵敏度公式. 这些公式表明稳态性能灵敏度很容易通过网络势能进行计算.

| Abstract: | By using the approach of the infinitesimal generator perturbation, the problems of sensitivity analysis of the steady-state performance with respect to the parameter perturbation are discussed for a class of Markov processes. Then the sensitivities of steady-state performance are studied in closed state_dependent queueing networks. Sensitivity formulas of several kinds of the steady-state performance are given for parameter-dependent performance functions. These formulas show that the sensitivities of steady-state performance can be easily calculated by the potentials of networks. |
