摘要


本研究將針對案例公司製造部門的粉料進行相關研究,並找出作業流程中瓶頸的地方作為改善的契機,如備料的順序要怎麼安排與選擇才能在搬運原料時可以達到最短的搬運路徑,以減少與消除浪費,或是當粉料在進行盛料作業時,要如何解決盛料作業時所產生的浪費。綜和以上問題點,本研究將結合「精實生產管理」、「3D列印技術」、「搬運路徑規劃」來解決在案例公司中所發現的浪費,而根據本研究改善後的結果顯示,備料作業時間縮短近26.57%,並幫助案例公司週五的工作時間從12小時下降至8小時左右,因案例公司週五需準備接下來三天(週六、週日和周一)的備料作業,且經過本研究改善後,除了可以使公司節省加班費用以外,還可以讓員工們在週五時可以比以往提早下班回到家。

This paper is to find an efficient method for these jobs related to preparing the raw powder materials in a chemical company. We find that selecting a shortest path to convey needed raw materials to preparing room and designing an efficient process to prepare these materials are the two most important jobs. These two jobs take most of the time of the works of preparation. We use the concepts of "lean production management", "3D printing technology", and "Route planning" to find the wastes of these two jobs and, then, provide the strategy to shorten almost 26.57% of the working hours for the preparation process. The result implements in a chemical company and helps the company to shorten the works of preparation on Friday from 12 hours to around 8 hours as the company has to prepare the raw materials for the production lines for the coming three days, Saturday, Sunday and Monday. Thus, the company can save overtime pay and, meanwhile, the worker for the work of preparation can leave for home much earlier on Friday than before.
