Application of Lean Approach to Improve the PracticalStudy of Plant Processes - A Case Study of MT Enterprise

指導教授:林亮宗[[abstract]]在傳統金屬加工產業中往往都是只顧著大量生產製造，以為產能越多收入就越多，忽略了在整個生產製造的流程中其實隱藏著許多不必要的浪費，及無附加價值的流程。但目前市場趨勢，客戶不斷的要求降價供應，在當今的微利時代，只有降低成本才能創造利潤，要降低成本就是要排除浪費，而精實生產管理講求「去除每一個流程步驟中的浪費，以縮短前置時間、降低成本、提升品質、創造價值、改善安全性及提升員工士氣」。本研究將精實生產管理手法，運用在物料作業流程上，同時導入5S、目視化管理等，經由流程再造，達到流程時間縮短、外觀品質提升、人力成本縮減、降低倉儲空間、改善搬運的浪費等幾項具體有形的改善效益，在改善過程中亦無形的提升整體員工士氣，並能降低成本、創造利潤讓個案公司對於改善能更有信心，不會在墨守成規、埋頭苦幹，卻無法為公司創造更多的利潤，使個案公司在艱難的環境中，能夠永續經營，創新價值，回饋社會。[[abstract]]In the traditional metal Processing industries are often desperately seeking only to manufacturing, with a total production capacity of more that more revenue, but ignored in the whole manufacturing process is actually hidden a lot of unnecessary waste, and non-value added processes . But the current market trends, customer demand for lower prices constantly supply in today's era of little profit, and only to reduce costs in order to create profits, to reduce costs is to exclude waste, and lean production management emphasizes "Every one process step to remove the waste in order to shorten lead times, reduce costs, improve quality, create value and improve safety and boost staff morale. "In this study, lean production management techniques, the use of the material on the processes, while import 5S, visual management, etc., through process reengineering, to shorten the process time, the appearance of quality improvement, reduced labor costs, reduced storage space and improve the handling of waste, etc. tangible improvement in several specific benefits, also in improving the process of improving overall employee morale invisible, and can reduce costs and create profits for improving case company can make more confident, not legalistic, work hard, but not for the company create more profits, so that the case company in a difficult environment, to sustainable development, innovation and value to society
