Manufacturing processes of some major ponent are desirable to follow the FMS concept in a customized manufacturing environment. In the case study that follows,a wing assembly process is examined by means of discrete simulation modeling.There are more than thirty plex processes applied to more than fifteen machine classes in this example .Most processes require a different number of labor entities from various labor overall pace of the whole system is desired to be a variable that impacts the process time of all related processes,as well as the number of assigned modular approach to MCM system design not only benefits the overall performance of flexible MCMsystem,but also enhances simulationmodeling exercises. Discrete event simulation technology in this study employs the same platform concept as in modeling highly flexible and rapid reconfigurable production modeling methods reflect manufacturing processes according to the everychanging customized fundamental manufacturing process parameters,such as layout reconfigurations, and resource reallocations, can be derived ahead of time from the simulation models.A highlevel process flow of this simulation model is shown below in Figure 541, where sourcel1 generates ining parts according to the system takt time with optional statistical distributions. Buffer S receives ining parts via the only crane resource in the system. The part will then be lifted by the crane to the machine B where multiple processes will be performed by multiple resources. The part then continues to move from the machine B to the machine P, the end of the process line. Multiple processes are assigned throughout this line on each machine. An additional process is needed in the middle of the line where the part will be transferred to the buffer A followed by a couple of external processes. Afterwards, buffer A receives the part and calls for the overhead crane to transfer the part back to buffer T where the part will continue through the rest of the process. At the end of the line, the part goes from
