考虑$\left( {s,S}\right)$ 库存策略的易逝品$M/M/1$ 排队库存系统, 其中库存为空时服务员多重休假, 休假时间服从指数分布. 顾客的到达过程服从泊松过程, 服务员的服务时间, 易逝品的寿命和补货时间均服从指数分布. 首先, 利用拟生灭过程给出系统的稳态条件. 其次, 研究忽略服务时间的$M/M/1$ 休假库存系统模型, 并求出了系统的稳态分布. 在此基础上, 进一步研究具有正服务时间的$M/M/1$ 休假排队库存系统模型, 并得到了系统队长, 库存水平和服务员状态的乘积形式的稳态联合分布. 此外, 还计算了系统的性能指标, 并给出了系统单位时间的平均费用函数. 最后, 利用数值算例分析系统参数对一些主要性能指标的影响, 并利用遗传算法计算系统最优库存策略和最优平均费用.

In this paper, we consider a continuous review $M/M/1$ queueing-inventory system with perishable items and $\left( {s,S}\right)$ policy, where the server takes multiple vacation which follows an exponential distribution when the on-hand inventory level is zero. Customers arrive according to a Poisson process, and the service time, the life time of each item and the lead time are assumed to be exponentially distributed. Firstly, the stability condition of the system is derived by using quasi-birth-and-death process theory. Then, we consider an $M/M/1$ inventory system with server's vacation where the service time is negligible. The steady-state distribution of the system is derived. Based on this distribution, we further analyze an $M/M/1$ queueing-inventory system with server's vacation and positive service time. The stationary joint distribution of the queue length, the on-hand inventory level and server status is obtained. Besides, some performance measures of the system and the expected cost function per unit time are calculated. Finally, the effect of the parameters on some important performance measures is analyzed by numerical examples. The optimal inventory policy and the optimal expected cost are calculated by using the genetic algorithm.
