A solution of dynamic manufacturing resource aggregation in CPS

Market diversification and economic globalization bring various uncertainties to the completion of manufacturing task. It requires manufacturing resource aggregation (MRA) could adjust to dynamic changing factors (DCFs) that happen during the life cycle of MRA. The emerging Cyber Physical Systems (CPS), in which the real-time states of physical resources are fully sensed, enable to identify the DCFs in time. This supports to realize the real dynamic MRA. Take CPS as background, the paper focuses on dynamic MRA which includes two key issues, manufacturing resource virtualization model (MRVM) and dynamic service composition. In order to give a complete manufacturing resource view, MRVM which contains both static and dynamic information is built. Based on the analysis towards life cycle of MRA, the paper proposes a dynamic MRA architecture. And as the core parts of it, the implementation process of manufacturing resource service composition and a multi-level dynamic adjustment strategy are described in detail. At last, we make a conclusion.
