Abstract: Aiming at the characteristics of users'complicated variable requirements and manufacturing resources'dispersed heterogeneous in cloud manufacturing environment, a multi-resolution clustering task allocation method which could get efficient match of demand ability was proposed to achieve dynamic sharing and intelligent distribution of manufacturing resources. According to characteristic of task goal, appropriate parameters were selected to build function of clustering distance, and the multi-resolution clustering was developed based on this distance. Tasks were decomposed and distributed to corresponding resources along with the clustering process, and a hierarchical structure of demand ability in cloud manufacturing system was obtained. It was a feasible structure to solve the problem of resource efficient allocation and to realize the dynamic matching between requirements and resource ability in cloud manufacturing system. Through examples, the process of proposed allocation scheme was illustrated, and it was proved to be an effective way to make full use of broken manufacturing capacity in cloud manufacturing.
