Better human relations 2. Improved operator expertise 3. Less inprocess inventory and material handling 4. Faster production setup Group Technology: Transition from Process Layout 1. Grouping parts into families that follow a mon sequence of steps. 2. Identifying dominant flow patterns of parts families as a basis for location or relocation of processes. 3. Physically grouping machines and processes into cells. 重組工序原則 ： 1） 組合工序工時不大于節(jié)拍； 2）組合工序符合工步順序原則； 步驟： ① 列出所有可能作為第 i工序的工步組合方案； ② 求各編組方案后剩余時間可能組成的最少工作地數(shù)； ][ 1rtTiSix xki? ????Ski = 第 i工序，第 K編組方案的可能最少工作地數(shù)； 全部工步 5 6 5 5 7 8 7 7 10 10 11 9 4 8 11 5 9 5 10 5 6 8 5 5 7 5 8 6 6 5 10 5 10 5 9 7 6 6 6 6 10 6 4 6 5 計算流水線所需配備的工人數(shù) 手工操作流水線 i 工序上
