中文摘要 | 本研究旨在探討多製程繼產之生產排程設計,以鏈條製造為例。鏈條多為零工式生產,訂單具多樣性,基本製程包括沖壓、小軸、布斯、熱處理、噴砂、滾筒、鏈接等,雖然生產流程短,但多樣化的零件與多樣的生產製程卻使排程系統顯得複雜而不易控制。從實務觀點,本研究在考量鏈條之製程特性,以滿足顧客需求,及確保工作最大延遲時間最小、平均延誤時間最小、延後工件數最少等為目標,採取最早到期日(EDD)之排程法則來設計排程系統。本研究根據各製程特性,例如零件最適生產機台、生產最大批量等,來尋求高生產效率之生產順序。再經由經濟生產批量、共用模具或共同加工條件、易混料另件等特性,決定需求單是否拆、併單設計,並考量不同另件之接續生產、或隔料或不可接續生產等,以「降低生產成本」為目標,設計出各製程之排程邏輯。本研究提出之生產排程設計邏輯,對於產業現實環境中普遍存在的多製程生產,具有重要的參考價值。 |
英文摘要 | The objective of this paper is to design the production scheduling logic rules for the multi-processes manufacturing of chain. The manufacturing of chain usually adopts job shop process to produce high varieties of chain to satisfy the requirements of distinct customer orders. The manufacturing processes of chain, by sequences, involve pressing, pin-process, bushing-process, heat-treatment, sand-blasting, barrel-finishing, and final assembly. The interrelated multiple manufacturing processes makes the production scheduling problem more complex and less easily to control. This research applies Earliest-Due-Date (EDD) rule to schedule the job sequences for each production process of chain in order to ensure the scheduling goals of minimizing the maximum lateness, minimizing average lateness, and minimizing number of trady jobs. The proposed logic, first, considers the process characteristics such as the most adaptive machine to fabricate parts and the maximum production lot size to schedule the production sequences. By considering other process characteristics such as economic production lot size, sharing mold/machine, and avoiding the possibility of mixing different parts, the decision regarding whether to disaggregate or aggregate the orders is then determined. In addition, the possibilities of consecutive, non-consecutive, and/or segregation production for different parts are also considered to design the scheduling logic for each process. The proposed approach would provide the industry with multi-process production environment a more practical and valuable scheduling decision tool aiming at reducing production costs. |
