This study analyzed overall loss through time loss, performance loss, and material loss by expanding the manufacture value process. Overall process loss (OPL) and overall line loss (OLL) were developed as indexes to select key improvement targets. First, Pareto analysis was used to identify process. The ICAM (Integrated Computer Aided Manufacturing) Definition (IDEF) was then employed to inform improvement decisions regarding the loss item. Finally, new key improvement goals were identified from the updated OLL, with continual improvement. The contributions of this study are the development of the indexes, OPL and OLL, based on overall loss, the improvement decision model, and the construction of a mechanism whereby sustainable reduction of overall loss can be achieved. 收起
