Abstract: Based on the strong urges for improving production preparation process, shortening production cycle, enhancing production planning and control ability and promoting development level of high-end manufacturing industry, network diagrams to describe manufacturing process sequence of modules in complex system were drawn. Methods of modularity theory, manufacturing techniques, project management and optimization theory were considered. Integer programming model to determine production cycle was built. A case study was provided then. Production cycle of the entire manufacturing system and corresponding critical manufacturing path were obtained by using optimization solution software CPLEX. The solving results were used to make production preparation plan and build production plan. After adopting modular techniques, production plan and production preparation plan can go on according to the principle of maximum parallelism and production preparation can be finished before production plan begins. Production cycle is greatly shortened. The effectiveness, accuracy and superiority of the model were validated.

Key words: complex system manufacturing, modular production, integer programming, production planning, production cycle
