Efficient Simulation of a Tandem Queue with Server Slow-down
Tandem Jackson networks, and more sophisticated variants, have found widespread application in various domains. One such a variant is the tandem queue with server slow-down, in which the server of the upstream queue reduces its service speed as soon as the downstream queue exceeds some prespecified threshold, to provide the downstream queue some sort of ‘protection’. This paper focuses on the o...
متن کاملA Tandem Queue with Server Slow-down and Blocking
We consider two variants of a two-station tandem network with blocking. In both variants the first server ceases to work when the queue length at the second station hits a ‘blocking threshold.’ In addition, in variant 2 the first server decreases its service rate when the second queue exceeds a ‘slow-down threshold,’ which is smaller than the blocking level. In both variants the arrival process...
متن کاملSimple and Efficient Importance Sampling Scheme for a Tandem Queue with Server Slow-down
This paper considers importance sampling as a tool for rare-event simulation. The system at hand is a so-called tandem queue with slow-down, which essentially means that the server of the first queue (or: upstreanm queue) switches to a lower speed when the second queue (downstream queue) exceeds some threshold. The goal is to assess to what extent such a policy succeeds in protecting the first ...
متن کاملA tandem queue with delayed server release
We consider a tandem queue with two stations. The first station is an s-server queue with Poisson arrivals and exponential service times. After terminating his service in the first station, a customer enters the second station to require service at an exponential single server, while in the meantime he is blocking his server in station 1 until he completes service in station 2, whereupon the se...

We consider a tandem queue with two stations. The first station is an s-server queue with Poisson arrivals and exponential service times. After terminating his service in the first station, a customer enters the second station to require service at a single server, while in the meantime he is blocking his server in station 1 until he completes service in station 2, whereupon the server in stati...
