Modeling and optimization of manufacturing service collaboration based on digital twins
摘要
With the gradual interconnection and integration of manufacturing resources in the physical and virtual space, it has become an inevitable trend to establish the manufacturing service collaboration (MSC) mode of virtual and real fusion, which can meet the personalized and complex manufacturing requirements under the new situation. In order to realize this collaboration mode, how to develop from static service collaboration in virtual space to MSC under the fusion of virtual and real space is the key core. In this paper, a digital twin-driven manufacturing service collaboration method (DT-MSC) is proposed to solve this problem. It discusses service collaboration description method combining static encapsulation and dynamic awareness, which describes and maps the static resources and dynamic states of manufacturing services. Then, it proposes the basic model of service collaboration by taking elements of virtual and real as the object, including physical object-physical object, physical object-virtual model, and virtual model-virtual model. Besides, it designs a service collaboration monitoring mechanism containing multi-service information to improve the success rate of service collaboration. This method provides possibility for realizing the transformation from traditional MSC into digital twin MSC.
