%A P. Desruelle %T An Analytical Model for Closed Networks with a General Single Queue and an Infinite Server Station %X In this paper we propose a new analytical model to solve a class of closed queuing networks with general servers and with a small number of customers. This model can be applied to analyze problems such as the machine-repairman problem and simultaneous resource possession. Our algorithm is based on exact mean value analysis and on two-moment approximations of GI/G/l queues. The model gives good results for a large range of the network parameters. %C IIASA, Laxenburg, Austria %D 1994 %I WP-94-018 %L iiasa4191
