Abstract: Multi-product manufacturing systems operating under CONWIP control are often modeled as closed queuing networks with synchronization stations. Performance analysis of these systems can be challenging, especially when batch size constraints are explicitly considered. This research develops a new approach for evaluating the performance of these systems based on parametric characterizations and traffic process approximations. The approach explicitly models the effect of batch size constraints on the departure process and waiting times at the different stations in the network to derive new characterization equations. These equations are used to derive a set of linking equations that is solved using an iterative algorithm to obtain estimates of network performance. Numerical studies indicate that the proposed method is yields fairly accurate performance estimates and can be useful in evaluating tradeoffs that guide managerial decisions.
