中文摘要 本研究以液晶化學產品製造過程中原物料投料耗損為個案,希望透過六標準差的手法,來降低液晶化學產品在投料過程中原物料的耗損,並為個案公司節省原物料的損耗成本。在專案過程當中採用六個標準差專案管理方式DMAIC為架構進行專案改善;在分析階段,利用SIPOC圖、特性要因圖、柏拉圖找出在投料製程中原物料損耗的主要原因,之後並找出造成原物料損耗的因子,並針對這些真因提出矯正措施。在改善階段,針對不同形態之原物料採用不同工具協助投料,求得最佳的手法,並驗證與收集改善效果。最後在控制階段,則是由專案負責人交由產線單位執行及監控製程,以完成整個專案。在經過執行將近半年的努力後,並有效將原物料的耗損降至最低,也達到公司的期望與目標。
ABSTRACT This research is a case study which focuses on material loss reduction during the dispensing process of liquid crystal chemical product. This study hopes to adopt the Six Sigma project management approach (DMAIC) in order to reduce raw material consumptions and analyze the issues in the dispensing process, also save the raw material costs in this case study company. During this study period, in the analysis phase, the project team analyzes critical factors by using several tools such as SIPOCP diagram, Cause & Effect diagram and Pareto Chart in order to find the root cause factors of raw material loss issue. In the improvement phase, we use several different tools to help improve the loss issue for different types of raw materials by collecting experiment data and finally we obtain a better solution for each type. In the control phase, the project leader releases the improvement methods for implementation in production line. After the implementation of the half-year effort, it can definitely reduce raw material costs and also achieve the company’s expectation and objective.
