【摘要】:針對多品種小批量的生產(chǎn)過程,依據(jù)產(chǎn)品相似性判斷條件把同一工序中滿足相似性判斷條件的不同產(chǎn)品構(gòu)建為一個零件族,并采用歷史數(shù)據(jù)與實(shí)時數(shù)據(jù)相結(jié)合的方法收集樣本數(shù)據(jù)。對樣本數(shù)據(jù)進(jìn)行標(biāo)準(zhǔn)化轉(zhuǎn)換,采用MINITAB軟件對轉(zhuǎn)換后的數(shù)據(jù)進(jìn)行檢驗,表明經(jīng)過變換之后的數(shù)據(jù)符合建立控制圖的條件。在進(jìn)行數(shù)據(jù)變換的時候采用實(shí)時均值的方法,使得隨著生產(chǎn)的進(jìn)行,控制圖的控制界限在不斷變化,增強(qiáng)了控制圖的檢出能力。使控制圖能更好的反映生產(chǎn)過程的實(shí)際情況,并通過實(shí)例進(jìn)行分析。
[Abstract]:In view of the production process of multi-variety and small batch, according to the condition of product similarity judgment, the different products which satisfy the similarity judgment condition in the same working procedure are constructed into a family of parts. The method of combining historical data with real-time data is used to collect sample data. The standard conversion of the sample data and the test of the transformed data by MINITAB software show that the transformed data accord with the condition of establishing the control chart. In the process of data transformation, the method of real-time mean value is used, which makes the control limit of control chart change continuously with the production, and enhances the ability of detecting control chart. The control chart can better reflect the actual situation of the production process, and through an example to analyze.
