Webcontrol. The same authors discuss stationary approximations to non-stationary problems in [12]. Green and Kolesar [3, 4] use a pointwise stationary approximation for the congestion in a non-stationary system. Although, in the present study we use the same term, “PSA”, to relate to a dyna mic control scheme rather Webtransformation of a stationary G=G=1 model, so that the queue length distribution is stabilized as time evolves. However, the time-varying virtual waiting time is not stabilized. ... ffi scaling, pointwise stationary approximations. 1. 1 Introduction In this paper we study controls to stabilize the performance of a queueing system with a time-
