多工程直列形加工ラインが連結した自動組立生産システムの挙動解析

An approximation method is proposed to estimate the system production rate for an automatic merge machining-assembly production system in which L parts are machined in multi-stage series lines and are assembled. In this method, the system is decomposed into L series machining lines, each of which considers the parts delay occurring in other series machining lines. From the comparison between approximation and simulation results, it is found that the estimation error is very small. Furthermore, we study the effects of system parameters on the system production rate. The main results are as follows. (1) As the number of machining lines feeding assembly parts increases, the production rate decreases but the decrease becomes slight. (2) When the number of stages in machining lines is greater than two, the number of stages has little effect on the production rate.
