Cloud manufacturing oriented automatic composition technology of models

The life cycle of cloud manufacturing involved the model-based activities. Under the environment of Internet oriented cloud, a large number of black box, heterogeneous models were accumulated, and the traditional retrieval and match methods could not satisfy the demand of massive model management. Thus the model composition should be taken into account in the process and the correctness of the time dynamic characteristics after composition should be ensured. Based on the composition approach of top-level modeling, semantic descriptions to each event of interactive scenarios among models were added, and existing redundant and mutually exclusive in the composition process were eliminated by planning method. Thus the combination of dynamic behavior was realized. The application example showed that the characteristics of highly scalable and on-demand aggregation could be achieved in the model resources management of cloud manufacturing by introducing models' automatic composition technology.
