摘要: 多领域制造资源的聚合与服务封装直接关系到云制造服务的可检索性与易用性,是实现制造能力共享的关键。针对因缺乏关键资源信息或制造活动过程特征,以及服务特征属性不确定性大等导致云服务信息粒度过粗、查准率低的问题,构建了以人、机、料、法、环为核心要素的制造元活动模型以实现多领域资源颗粒的有效聚合,并基于商空间粒计算理论对资源簇的制造能力进行逐层封装,提出基于灰相似粗糙集的云制造服务粒层递归搜索算法以解决服务特征属性的不确定性问题,建立了一套元活动模型驱动的多领域制造资源粒层化服务封装与检索方法。通过某金属构件快速成形云服务的检索算例验证了所提方法的可行性。

Abstract: Polymerization and service encapsulation of multi-domain manufacturing resources were the key of sharing manufacturing capacity and directly related to the searchability and usability of cloud manufacturing services.Aiming to solve the problems of coarse-grained information and low precision ratio of cloud service,which was due to the lack of key resource informations or the characteristics of manufacturing processes and the uncertainty of service attributes,a meta-activity model of manufacturing with human,machine,material,method and environment as the core elements was constructed to realize intelligent aggregation of multi-domain resource particles firstly.Then the manufacturing capacity of resource cluster was encapsulated layer by layer based on quotient space granularity theory.A hierarchical recursive search algorithm of cloud manufacturing service level was proposed to solve the uncertainty of service attribute based on gray similarity rough set model.Finally,a set of meta-activity model driven multi-domain manufacturing resource grain layered service encapsulation and its retrieval method were established.The feasibility of the proposed method was verified by a retrieval case of cloud services for rapid prototyping of metal structures.

Key words: multi-domain, grain layered, meta-activity model of manufacturing, cloud service retrieval
