两服务台串联排队系统的逗留时间的强逼近
Strong Approximation of the Sojourn Time for a Two-Stage Tandem Queue
-
摘要: 本文考虑了两服务台串联排队, 证明了重话务条件~(即服务强度\rho_1=\rho_2=1下逗留时间的强逼近,此处的逗留时间指的是一个顾客从到达系统到离开系统的这段时间,其强逼近是一个布朗运动的过程.Abstract: We obtain the strong approximation of the sojourn time progress for a two-stage tandem queue in heavy traffic, that is, the traffic intensity \rho_1=\rho_2=1. The sojourn time is the period from a customer's arrival to her departure, and the strong approximation is a function of Brownian motion.
