一类多站循环服务系统的状态与状态转移

A Type of Multi station Cyclic Service System's Status and Status Transition

探讨具有如下特征的多站循环服务系统：（１）队列容量有限；（２）每次服务对象受限；（３）实施非门限方式。论述的主要内容有：系统与队列运行特点；队列在服务期间的状态转移；队列在周期中的状态与状态转移；系统与队列的有关参量近似求解。

In this paper,we discuss a type of multi station cyclic service system.It is:(1)Limited capacity of queue;(2)Limited service object of each time;(3)Using no limited gate way. This paper mainly discusses the running characteristic of system and queue,the status transition of queue during service time,the status and status transition of queue in cycle and the approximate solution of parameters to system and queue.
