摘要

在企業體的生產系統中，不論是生產排程(Production Scheduling)或是預防維護(Preventive Maintenance, PM)皆是不可或缺的一環。有效的排程訂單策略能為企業帶來最大的生產力及盈收，而預防維護乃在保持設備於良好的運作狀態，且適時必要的修護，更得以使整個生產系統得以運作自如。而生產計畫一般而言包括生產排程及維護排程兩部分，預防維護和生產排程應是二個相互依賴的動作，但他們的執行卻是經常獨立的。
近年來，有不少學者研討生產排程與預防維護計畫於單機台之整合相關議題。本研究將延續相關議題於流線型雙機台之生產型態，整合機台預防保養與排程狀況之探討，並以總加權工作延遲懲罰成本最小化做為本研究之目標。本研究將透過大量數據代入整合模式與非整合模式中，比較雙方之結果並針對整合之效益做其分析。實驗結果顯示出以整合模式會有26%的成本改善效益。

Preventive maintenance planning and production scheduling both have great importance in enterprise’s production system. The effective scheduling strategy will bring more production and profit for the business. On the other hand, preventive maintenance planning which can keep machine in perfect situation will make the whole production system smooth in right moment. Generally, production planning include production scheduling and preventive maintenance planning, but they are two activities that are inter-dependent but most often performed independently.
Recently, a few scholars have studied about integrated preventive maintenance planning and production scheduling for a single machine. The discussion will continue in this study, and we propose an integrated model that simultaneously determines production scheduling and preventive maintenance planning decisions in two-machine flowshop so that the total weighted tardiness of jobs is minimized. We investigate the benefits of integration through a numerical study of small problems. We compare the integrated solution and its performance with the solutions obtained from solving the production scheduling and preventive maintenance planning problems independently. The numerical results show an average reduction of 26% in expected total weighted tardiness.
