Abstract: To strengthen regional collaborative manufacturing and to realize service-oriented manufacturing,an adaptive organization and finding mechanism of Multi-granularity Manufacturing Resource (MMR) based on geographic region and Manufacturing Resource Classify Tree (MRCT) was proposed.The MMR model and the multi-granularity manufacturing service model based on business process were constructed to be the basis of collaborative resource storage,and then the organizational structure of MRCT and MMRs were discussed.Furthermore,the adaptive mechanism of MMRs'organizational structure was discussed,including dynamic joining and exiting of MMR and MMRs'maintenance,splitting and merging of resource node based on load sensing,and MMR's discovery algorithm based on the retrieval and the three phase matching was designed.Through the comparison of algorithms performance,the classification retrieval algorithm based on MRCT had faster searching performance than similar algorithms,and multi-granularity service had faster than combined service by several single granularity services in resource discovery performance.The validity of proposed model and related algorithms were verified through the simulation experiment.
