【摘要】 本文研究了具有N策略和负顾客的反馈抢占型的M/G/1重试可修排队系统.所有顾客(包括正顾客和负顾客)的到达都是泊松过程,服务器是可修的.利用吸收分布,求出了系统存在稳态的充分必要条件.利用补充变量法,求出了系统稳态时系统和重试区域中队长分布的概率母函数,以及其他一些重要的排队指标.更多还原

【Abstract】 In this paper,the M/G/1 retrial G-queues with N-policy、feedback、preemptive resume and unreliable server is studied.Arrivals of customers(both positive customers and negative customers)are a Poisson process and the server may break down for the arrivals of negative customers.The necessary and sufficient condition for the system stability is obtained along with method of absorbed distribution.The generation function of steadystate distributions of the number of customers in the system and orbit and other important queueing quantities are obtained along with method of supplementary variables.更多还原
