摘要

在包含若干个服务器周期性参加的有限容量队列的系统中，给出了客户平均等待和停留时间的精确结果。采用广义随机Petri网(GSPN)对系统行为进行了描述，并利用GSPN分析软件GreatSPN对系统性能指标进行了数值计算。首次精确计算了马尔可夫多服务器多唯一系统中顾客的平均等待时间和逗留时间;它们以前是由其他作者使用近似模型估计的。

GSPN models of multiserver multiqueue systems

Exact results are presented for the average customer waiting and sojourn times in systems comprising a number of finite-capacity queues cyclically attended by several servers. The system behavior is described using generalized stochastic Petri nets (GSPN), and the performance indices are obtained numerically by means of GreatSPN, a software tool for the analysis of GSPN. The average waiting and sojourn times of customers in Markovian multiserver multiunique systems are computed exactly for the first time; they were previously estimated by other authors using approximate models.<>
