Abstract
In this article, an attempt is to provide new setup-oriented dispatching rules for a stochastic dynamic job shop scheduling problem while considering sequence-dependent setup times. A discrete event simulation model of the stochastic dynamic job shop manufacturing system is developed for the investigation purpose. Nine dispatching rules taken from the literature are incorporated in the simulation model. Four new setup-oriented dispatching rules are proposed. The simulation experiments are conducted under shop utilization percentage of 90% and setup time less than processing time. The results indicate that the proposed new setup-oriented dispatching rules provide better performance than the existing dispatching rules taken from the literature.
