| 摘要: | 現今在各產業間競爭激烈的態勢中，企業內部積極尋求將利潤最大化及成本最小化的管理方法以提升產業競爭力，其中精實生產（Lean Production）與六標準差方法（Six Sigma）已在產業激烈競爭的環境中受到廣泛的採納與運用，其顯著的改善成效已眾所皆知。
精實生產著重於降低生產中浪費，縮短製程前置時間及持續改善為其核心價值；六標準差著重於控制製程變異，系統性管控品質為其核心價值。精實管理的「速度」與六標準差的「品質」兩者之間如何取得平衡，精實六標準差（Lean Six Sigma, LSS）即提供在改善活動中又可兼顧實際效率的方法。
本研究以液晶製程中所使用之容器的清洗流程改善為個案，運用六標準差之手法，依界定（Define）、衡量（Measure）、分析（Analyze）、改善（Improve）、控制（Control）步驟進行專案改善，以現有的作業廠房與清洗設備，透過精實管理與六標準差的手法提出可縮短化工容器的清洗時間及兼顧其品質的有效改善方案，進而提升清洗作業效率，降低生產成本，同時可從中節省清洗製程中所浪費的資源與能源，藉此提升產業競爭力，也為企業社會責任盡一份心力。
;Today among dynamic competition in the industry, the enterprise will actively seek for management method regarding maximize profits and minimize costs to enhance industrial competitiveness, which Lean Production and Six Sigma methods has been widely adopted and used in the industry highly competitive environment, Significant improvement in their effectiveness has been well known.
Lean production focuses on reducing the production of waste, shorten process lead times and continued to improve; the core values of Six Sigma focuses on control process variation and systematic quality control. How to get balance between the "quality" of Six Sigma and "Speed" of Lean Management, Lean Six Sigma (Lean Six Sigma, LSS) is providing in improvement activities but also take into account the actual efficiency.
In case study, the improvement of container cleaning process for LCD manufacturer as an example, the use of Six Sigma′s approach, according to the definition (Define), measure (Measure), analysis (Analyze), improve (Improve), control (Control) step carrying out ad hoc improvements according to existing plant operations and cleaning equipment to shorten cleaning time of container including quality improvement program through lean management and six Sigma practices, thereby enhancing the efficiency of cleaning operations, reduce production costs, meantime, you can also save the cleaning process in wasted resources and energy, thereby enhancing industrial competitiveness, but also but also contribute to corporate social responsibility. |
