Abstract

Linearizer is one of the best known approximation algorithms for obtaining numeric solutions for closed-product-form queueing networks. In the original exposition of Linearizer, the computational cost was stated to be O(MK/sup 3/) for a model with M queues and K job classes. It is shown that with some straightforward algebraic manipulation, Linearizer can be modified to require a cost that is only O(MK/sup 2/).
