A collaborative manufacturing execution platform for space product development

Space product development enterprise has the feature of single piece or small batch productions, in which the product manufacturing process changes frequently, key components need process preparation, and production scheduling problem is often complicated. According to the development process of space products, a collaborative platform under network-based manufacturing environment for space products development is proposed in this paper. The main structure of the platform and the cooperation process between each application modules are proposed. Moreover, a kind of dynamic job shop scheduling algorithm is presented. The algorithm is used to realize rapid response and adjust manufacturing plan when production or process plan has changed. Finally, a prototype system that supports space product manufacturing process management is developed and a case study is presented to demonstrate the efficiency of proposed algorithm.
