Abstract: To improve the optimum efficiency of resource to satisfy the user demand,the business process was considered into selection process.Through analyzing the characteristics of cloud manufacturing resource,six evaluation indexes were proposed which included service time,service quality,service cost,usability,compositionality and trust.According to the business process,the resource dependency relationship model was built and the resource graph was also formed.The business process was divided into the resource dependence subprocess and the non-existent resource dependence subprocess.These typical indexes were used into subprocess to calculate resource optimal set,and all resource optimal set of subprocess were merged to solve resource optimal set of business process.An experiment was used to verify the superiority of proposed approach with consideration of business process.

Key words: cloud manufacturing, workflow, resource dependency relationship, resource selection, evaluation index
