【摘要】 本文推广了现有的摄动分析法,提出了队长摄动的概念,建立了能同时考虑队长和事件时间摄动的全状态摄动分析。文中应用全状态摄动分析成功地计算了系统性能指标对闭环网络内顾客数的灵敏性,实验结果验证了这一方法的有效性和准确性。更多还原

【Abstract】 This paper makes an extension to the existing perturbation analysis of discrete event dynamic systems and general queueing networks. The new concept of queueing length perturbation is proposed. A new method called full-state perturbation analysis is developed, in which the event time perturbations and queueing length perturbations are considered simultaneously. And it is also successfully used to calculate the performance sensitivity to the changes of customer numbers in closed queueing networks. Experimental results verify the validity and accuracy of this new method.更多还原
