IMPLEMENTATION OF LEAN MANUFACTURING IN PRODUCTION PROCESSES

To remain competitive, enterprises seek to improve their manufacturing processes by continuously pursuing improvements toward lower costs, higher quality, and shorter delivery times. Lean manufacturing involves a variety of principles and techniques, all of which have the same ultimate goal of eliminating waste and non-value-added activities in each production process to improve production quality and efficiency. In this study, the principle of lean production was used to develop a framework for lean manufacturing processes in the puttying area of a workshop. The goal was to reduce waste and improve productivity. Implementation results showed the total productivity of the puttying area's process was boosted significantly because bottlenecks were eliminated, employee turnover rates were cut, and the cycle time and work-in-process inventory were reduced. This research can be applied to other manufacturing industries and extended to a variety of other manufacturing processes to increase productivity and improve process cycle efficiency.

為了保持競爭力，企業都試圖改善製造流程，朝向低成本、高品質、交期短等目標持續追求改善。精實生產涉及各種原理和技術，最終目標是在每個生產過程中消除浪費和無增值作業，以提高生產質量和效率。在本研究中，以精實生產原則，開發個案公司施行精實製造的框架，以改善生產車間補土區域的過程，目的是要減少浪費並提高生產率。由於消除瓶頸，實施成效降低了員工的流動率、週期時間及在製品（work-in-process, WIP）庫存，總體生產率顯著提升。本研究成果可供其他製造產業和其他各種製造過程參考，以提升製程效率及增加產能。
