时间窗约束下基于GRA的制造云服务选择研究

Research on manufacturing cloud service selection with time window constrain based on GRA

制造云服务的选择是组建云制造虚拟定制化供应链的关键环节,合适的制造云服务是虚拟供应链成功运作的保障。文章界定了制造云服务的非功能属性,并以此确定为制造云服务的选择评价指标;在对特殊指标时间窗进行数据处理基础上,采用灰色关联度分析法对制造云服务选择问题进行求解。最后,通过算例验证了该方法的有效性与可行性。

The selection of manufacturing cloud service is a critical step in the formation of cloud manufacturing virtual customized supply chain, and the suitable service guarantees the successful operation of virtual supply chain. This paper defines the non- functional attribute of manufacturing cloud service which is determined as the evaluation index of manufacturing clouservice. On the basis of processing special indicators, such as the time window, the article addresses the problem of manufacturing cloud service selection using the Gray Relational Analysis method. Finally, a numerical example is carried out to verify the validity and feasibility of the method.
