Abstract: Production scheduling often poses a huge challenge due to the ever-changing production environment and competitive global market. The changes result to various layout design modifications from simple flow line and job shop to hybrid flow shop (HFS). This research is conducted to determine a scheduling rule suitable for the HFS production area. Simple and combined priority dispatching rules are tested to identify the most effective rule in producing products on time and to avoid penalties caused by production delay. WITNESS software is utilised to develop the production line layout model and to simulate scheduling rules. The rules are then analysed through one-way analysis of variance. Newman-Keul's test is performed to compare the significant difference of each rule from the others. Analysis shows that the shortest imminent rule is the most significant rule that can be implemented in the production environment to achieve effective scheduling and maximised throughput.
