Abstract: Integrating physical manufacturing resources and transforming to logic manufacturing resource was the main task for resource virtualization in cloud manufacturing, there was no feasible solution to this problem at present. Based on the mining of workflow log and definition of activities with resource configuration in workflow model, the service frequencies of physical manufacturing resources composition were calculated from two levels, business process and activity instance respectively. Then multi-granularity composition set was obtained by merging the two results. This approach could supply the reliable assurance for mapping from physical to virtual manufacturing resource. Finally an experiment was proposed to verify the effectiveness of this method.

Key words: cloud manufacturing, workflow, resource composition, resource virtualization, physical manufacturing resource
