【摘要】：为了通过云制造服务实现对制造资源能力的精准调度与使用,云制造模式要求制造资源的虚拟化过程必须保证云制造服务所描述的相关能力与原制造资源所提供的能力在逻辑上具备严格的一致性.为此,提出了基于同态映射的制造资源虚拟化机制:通过在物理资源层和云服务层之间定义抽象的虚拟能力层,在解耦物理资源与云服务之间直接映射的同时,分别定义了制造资源-虚拟能力、虚拟能力-云服务的同态映射函数;采用基于语义相等映射的实现原理,将物理资源的能力及其所需的依赖条件进行同态抽象转换,并通过初步的案例仿真说明制造资源在同态映射过程中保持了能力语义的不变性.
[Abstract]:In order to achieve accurate scheduling and utilization of manufacturing resource capacity through cloud manufacturing services, The cloud manufacturing model requires that the virtualization process of manufacturing resources must ensure that the related capabilities described by the cloud manufacturing services are strictly consistent with the capabilities provided by the original manufacturing resources. Therefore, a manufacturing resource virtualization mechanism based on homomorphic mapping is proposed. By defining abstract virtual capability layer between physical resource layer and cloud service layer, we decouple physical resource and cloud service directly. The homomorphic mapping functions of manufacturing resource virtual capability and cloud service are defined respectively. Based on the realization principle of semantic equality mapping, the ability of physical resources and their dependent conditions are transformed into homomorphic abstractions. A preliminary case study shows that manufacturing resources maintain the invariance of capability semantics in homomorphic mapping.
