摘要
研究一类受控闭排队网络系统的性能优化问题 .文章引进了两个基本概念 :折扣代价α 性能势和平均代价性能势 ,并且讨论了这两个性能势之间的一个关系式 .在一般的假设条件下 ,我们应用性能势的基本性质直接建立了无限时间水平平均代价模型的最优性方程 ,并且证明了在紧致集上最优解的存在性 .最后给出了一个策略优化的迭代算法并通过一个实际算例以说明该算法的效果 .
This paper deals with the performance optimization problem of a class of controlled closed queueing network systems (CQNS). We introduce two fundamental concepts: the discounted cost α-performance potentials and average cost performance potentials, and consider a fundamental relation between the two potentials. Under a general assumption, we establish directly the optimality equation for infinite time horizon average cost model and prove the existence of optimal solution in a compact action set by using properties of the performance potentials, suggest an policy_optimality algorithm and give a numerical example to illustrate the application of the proposed algorithm.
