精實六標準差結合模擬於探索最佳製程之研究-以輸配設備製造業為例

隨著科技日新月異，各產業競爭也越來越激烈，企業如何保有產品的競爭力、降低成本並且能快速回應顧客的需求，成為企業永續經營的重要課題。精實六標準差的手法由保留了六標準差的執行手法，同時加入了精實生產中的消除浪費及價值工程的觀念，於製程改善或品質改善的同時檢視製程作業中的浪費一併予以消除，不僅在專案改善過程中提升改善目標的品質水準外，亦同時降低許多成本的支出，使得企業更具有競爭力，本研究主要探討精實六標準差針對製造程序進行製程改善，針對精實六標準差進行製造程序的價值分析，同運用模擬軟體分析製造流程及其改善效益，最後建構最佳方案以做為決策之參考。於本研究中使用精實六標準差手法較過去的六標準差手法在專案執行過程中可快速檢視到製程中許多多餘的作業，設法消除除可消除時間亦可減少成本的支出，運用模擬分析可以發現作業中的瓶頸工作站，使得生產線平衡可提高成品的成品數及縮短材料等待的時間。

With the fast change of technologies, the competition among industries is fierce. It is an important issue for a sustainable business to keep competitive edge, to reduce the production costs and to quick respond the customer’s demand. Lean six-sigma was introduced in the study to address above issue. Lean six-sigma retain the process and quality improvement project steps from six-sigma, and add the steps for waste elimination and value engineering for process flow from lean production. The study first discussed the six-sigma, lean production and their variants; followed by elaborating the lean six-sigma. A case company, which had a successful six-sigma project history, was studied. The company introduced lean six-sigma as an experiment for its transformer production line. A project team was formed to carry out the project. Besides traditional six-sigma steps, manufacturing processes were carefully studied by the team to eliminate the wastes and to propose new, improved processes. Since the physical layout was not changed, the study used simulation to simulate original process and various new ones. Based on simulation analysis, the bottlenecks in the manufacturing process were identified. Optimal adjustment of resources was done through simulation to achieve higher quantity production and shorter waiting time. Finally, the study gave the summary and future recommendations.
