摘要
考虑带负顾客的GI/Geom/1工作休假排队.负顾客一对一抵消正在服务的正顾客(若有),若系统中无正顾客,到达的负顾客自动消失,负顾客不接受服务.服务规则为先到先服务.工作休假策略为空竭服务多重工作休假.用矩阵几何解方法,求得到达前夕系统队长的稳态分布、队长分布的概率母函数及平均队长.
A GI/Geom/1 queue with negative customers and working vacations was discussed.Negative customers removed positive customers only one by one at the tail(if present).When a negative customer arrived,if the system was empty,it would disappear.Negative customers need no services.The serve rule was first come first served.The working vacation policy was exhaustive and multiple working vacations.By using matrix-geometric solution,the steady-state distributions were obtained for the number of customers in the system at arrival epochs.And the generating function of distributions and the average value of the number of customers were obtained.
