e actual line process, which consists of many robots, a circulatory system of
vehicle hangers, and the logistics route, is much too long. e necessary functions
in the model are (1) quantitative analysis of availability according to practical pro-
duction conditions and determination of the optimum buering number between
each subline process; (2) measurement of bottleneck processes, specically, a sur-
plus or shortage of vehicle hangers at the joint process; and (3) implementation of
concurrent engineering for process planning to reduce lead time, from product
development to production preparation processes.
According to these functions, this system is incorporated by (a) grasping the rea
