同意樓上這須要大量數據統計
我們這裏的作法是將工序分成容易,中等,難三類
對這三類工序,各針對名新工,進行一個月的生產數據統計,當然須要觀察數據的一致性
統計後發現以下現象,僅供你參考(不同產品生產製程就不一樣)
容易 : 1st day : 65%, 2nd day : 80%, 3rd day 95% , 4th day over100%
中等 : 1st day : 60%, 2nd day : 65%, 3rd day 75% , 4th day : 85%, 5th day :95% , 6th day over 100%
難 :1st week: 50%, 2nd week : 80%, 3rd week 95% 4th week: over 100%, |
