Comparison of dispatching rules in job-shop scheduling problem using simulation: a case study

Industries nowadays must be able to quickly adapt with the customer and improve product quality to survive in the competitive edge. Job shop scheduling is crucial in the manufacturing world and exists within most manufacturing sectors. In the manufacturing world, scheduling problems are extensively implementing the dispatching rules. The procedures are designed to provide good solutions to complex problems in real-time. This paper describes the importance of dispatching rules in improving the performance of the factory. This study evaluates total of44dispatching rules with the classification of hybrid and single rules. The performance of each rule compared and summarized to determine the final ranking for all the different dispatching rules. The result shown that MTWR (Most Total Work Remaining) rule performs well in almost all measurements as well as hybrid dispatching rules is not generating the best rules compared to single dispatching rule. A set of data from an automotive industry use to simulate the job-shop production floor.
