Research On Dynamic Scheduling Simulation Of FMS

FMS (F1exib1e Manufacturing System) is now a very importantdevelopmenta1 direction in current manufacturing industry. FMS isa new and advanced technique which is rapid1y deve1oping andapp1ied. FMS needs vast investment. The tactic of scheduling andcontro1 of FMS deep1y inf1uence on running efficiency and app1iedbenefit of FMS. So, the research on the tactic of the schedu1ingand contro1 of FMS is quite necessary.In this paper, the mode1ing and schedu1ing of FMS aredi scussed.The research on FMS dynamic schedu1ing is based on computersimu1ation. Some advanced techno1ogy such as object--orientedtechno1ogy and Petri net are used. A FMS dynamic schedu1ing mode1for genera1 purpose which can reflect its essence is created. Inmy paper, this mode1 using modern software techno1ogy isrealized. In schedu1 ing decision research, an idea ofvirtua1--process--queue is introduced, based on ana1ysis on FMSrunning, a FMS dynamic 1ook--ahead scheduling system isconstructed. Then a software under Visual C++ program environmentis developed. According to the ohtcome of this simu1ation system,Some ana1ysis on factors which affect the FMS economic goa1s area1so done.
