Most studies are done under steady state assumptions. The inherent flexibility of these systems in terms of input, volume or mix makes such an assumption hard to justify. In this paper, we investigate the convergence rate to steady state in simple queuing models that are often used to depict FMS's. the study reveals that steady-state conditions are not achieved during the execution of batches of moderate size. We therefore conclude that equilibrium models are appropriate for studying long-term planning problems, but, for the operational control of FMS's, it is highly desirable to study the transient behaviour of the system. On a broader scope, our investigation also shows that steady-state assumptions used in the analysis of any inherently transient system should be carefully validated| Item type | Current location | Collection | Call number | Status | Date due | Barcode | Item holds |
