| 摘要: | 六標準差是利用資料及統計分析來鑑別並解決問題的流程改善方法，而其採用的工具在選用上是需要調整才會符合實際運用的，有些工具是科學方法不允許調整，但有些判斷基準可依據實際需要做調整。本研究方法將依據需求，按照標準流程選用及調整合適的工具。 定義階段分三部份，1.個案緣由，2.顧客的聲音，3.關鍵品質特性。重點在於透過顧客的聲音轉換成關鍵品質特性，並量化為可量測的規格數據。 量測階段分兩部份，1. 評估量測系統， 2. 確認現行製程能力。評估量測系統用兩個方法，1. -R分析法，2. 變異數分析法。確認製程能力採用製程能力相關指標。 在分析階段，分為兩個部份，1. 建立改善目標，2. 找到變異來源。1. 建立改善目標，是透過整體產生產品中不良率最高的問題做為改善的目標，主要是利用柏拉圖。2. 找到變異來源，是利用特性要因圖和失效模式與效應分析。 在分析階段，分為兩個部份，l.找出關鍵少數的設定條件，2.驗證改善方案。找出關鍵少數的設定條件, 主要是運用實驗設計方法。2.驗證改善方案，主要以柏拉圖、製程能力指標和失效模式與效應分析做驗證。 改善階段使用實驗設計的方法找到重要的因子，於本階段再利用管制圖的監控，主要的目的是使製程能產生理想的結果。 Six-Sigma management is the processes which make use of data and statistics analysis to discriminate and solve problems. However the tool of its adoption in choosing to use is need to be adjusted then would match an actual usage. Some tools are sciences methods to disallow adjustment, but some judgment bases can do adjustment according to the effective demands. The origin studies a method and will choose to use and adjust suitable tool according to the standard process according to the need. Defining the stage divides into three parts, 1.Individual case reason, 2.The voice of customer, 3.Key quality characteristic. The point lies in becoming key quality characteristic through the orotund conversion of customer, and the quantity change into can the specification data of measurement. The measurement stage divides into two parts, 1. Evaluate measurement system, 2. Confirm current manufacturing process ability. Evaluating the measurement system uses two methods, 1. -The R analyzes a method, 2. The variation number analyzes a method. The ability of confirming the manufacturing process adopts the related index sign of the manufacturing process ability. Be divided into two parts at the analytical stage, 1. The establishment improves a target, 2. Find out variation source.1. The establishment improves a target, is through whole creation product in bad rate's highest problem is used as an improved target, mainly is make use of Plato.2.Find out variation source, is make use of characteristic important cause diagram and lose efficacy mode and effect analytical. Be divided into two parts at the analytical stage, l. Find out the enactment condition of key minority, 2.Identify an improvement project. Finding out the enactment condition of key minority is mainly a usage to test a design method.2.Identify an improvement project, mainly do an identification by the Plato, index sign and expired mode of the manufacturing process ability and the effect analysis. The method which improves the experiment design of the stage usage finds out important factor, |
