Abstract:

In order to effectively organize the resource services for cloud manufacturing and to support the complex user search,first,the key attributes of resource services are introduced in this paper.Next,the resource services are respectively registered according to their key attributes.Then,a layered resource service organization model for cloud manufacturing is proposed based on the distributed hash table,and five discovery algorithms respectively for five query types are designed based on the proposed model. Finally,the complexities of the proposed algorithms are discussed.Simulation results show that the proposed algorithms possess excellent performance and can effectively solve the complex search problems existing in the resource services for the distributed cloud manufacturing.

Key words: cloud manufacturing, resource service, organization model, discovery algorithm, distributed hash table
