摘要
应用随机服务系统的逼近理论,讨论了在港口装卸系统中有着广泛应用的一类排队模型——M/Ek/C随机服务系统排队数量指标的逼近算法.文中还对天津港第一港埠公司杂货船装卸系统进行了统计分析,并用本文所给出的逼近公式研究了该公司杂货船装卸系统排队模型——M/E_2/5随机服务系统,计算了该排队系统排队数量指标的分布及其均值的逼近解.
This article discusses the apporximation algorithm of queueing quantitative index for a class
of queueing model-M/EK/C stochastic service system which is applied widely to a port loading
and unloading system,using the approximation theory of stochastic service system. The statistical
analysis is done for the multi-purpose freighter loading and unloading system in the No. 1 Port
Company of the Port of Tianjin Authority,and the approximation formula given in this article is
applied in this company' s multi-purpose freighter loading and unloading system queueing mod
el-M/E2/5 stochastic service system. The approximation solution to queueing quantitative in-
dex' s distribution and mean value is calculated for this queueing system.
