Simulation analysis of lot streaming in job shops with transportation queue disciplines

In this paper we Study a multi-product lot streaming problem in a stochastic job shop with equal and discrete sublots. The problem involves splitting order quantities of different products into different number of equal sublots (NES) and analyzing the effects of sublot-related transportation queue disciplines (TRQD) for different performance measures. Our simulation results show that some combination of TRQD and NES alternatives are appropriate for some performance Measures. We also propose a simple heuristic to determine the NES of each product type to further improve the values of performance measures. (C) 2008 Elsevier B.V. All rights reserved
