摘要
考虑单个服务员的排队模型 G I( X)/ G I/1,顾客成批到达,来到间隔时间与服务时间分别是独立同分布的,比较两个这样的系统,证明了如果它们的基本随机变量有一定的随机序、凸序关系,则等待时间也有相应的随机序,凸序关系.
Two queueing systems GI (X) /GI/1 with Bulk arrivals and i.i.d. interarrival times and service time are considered;by comparing the two systems,it is proved that one′s has longer waiting time than the other if their basic random variabies have corresponding order relationships in stochastic ordering or in convex ordering.
