This makes the shop floor control difficult. The use of a suitable dispatching rule is the current method to reduce the shop floor control problems. As known those dispatching rules used are aimed at a single purpose. They are good from one aspect but not good from other aspects. Dabbas et al. [2001][2003a,b] proposed a combined dispatching criteria approach to meet multiple production purposes. In their study, they considered four factors, job critical ratio, job processing time, machine utilization, and line balance. From their simulation results, it shows the combined job dispatching method does provide better performances on both the on time delivery and the mean cycle time. However, in their study, they did not include the shop floor control strategy such as due date assignment calculation method, order release policy and total preventive maintenance (TPM) strategy. Is the combined dispatching method still better than others under different control strategy? The main purpose of this study is to propose an integrated job dispatching rule that including shop floor strategies. In this thesis, three shop control strategies, due date assignment, order release, and TPM, are considered, and 8 different scenarios are established. Based on Dabbas et al.’s method, in this thesis, 8 priority on-line modules are developed for each scenario. For comparison purpose, besides the priority on-line modules are used as the job dispatching method in the simulations, the single purpose dispatching rules, CR and SPT, are also used to perform simulations. The simulation results show the proposed integrated method provides 10% to 20% improvement on the on time delivery, variance of the on time delivery, mean cycle time, and variance of the mean cycle time. The integrated job dispatching method ensures the performance of the shop floor control.目 錄 致謝………………………………………………………………………I 中文摘要………………………………………………………………...II 英文摘要………………………………………………………………..IV 目錄……………………………………………………………………...V 圖目錄………………………………………………………………...VIII 表目錄………………………………………………………………….
