Hysteresis strategy for a M/M/1 retrial queue with a changeable service rate.
研究了在滞后策略下具有状态依赖服务率的M/M/1重试排队系统，得到了系统内呼叫数的遍历分布存在条件及公式，对排队系统设计和性能分析有参考价值。
The paper deals with a queueing system of the type M / M /1 with repeated calls and a state-dependent service rate in which the server is functioning under a hysteresis strategy. The existence condition and the formulae for ergodic distribution of the number of calls in the system are obtained.
