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

摘要： 为提高资源的优选效率,从而更好地满足用户需求,将业务过程因素考虑到资源选取过程中,通过分析云制造环境中资源的特点,构建服务时间、服务质量、服务成本、可用率、可组合率、可信任度六个资源评价指标,同时根据业务过程建立资源依赖关系模型,形成资源关系图,再根据资源关系图将业务过程划分成存在资源依赖关系和不存在资源依赖关系的子过程,将六个典型的资源评价指标运用在各个子过程中,求解各个子过程的资源最优集,合并各个子过程的资源最优集即可得到业务过程的资源最优集。通过实例证明了考虑业务过程的方法更优。
