Abstract:Dynamic service alliance based on multiple smart manufacturing cells, is not the basic organization formation for wisdom manufacturing platform to achieve the optimal resource allocation and network collaborative integration, but also the main service model for manufacturing enterprise to build complex business process and meet consumer personalized requirements. On the basis of the analysis of the architecture of wisdom manufacturing system, a business process oriented networked dynamic alliance model is proposed, and four types of alliance structures are distinguished. In order to construct an efficient dynamic alliance, a full life cycle based service composition framework is put forward from the point of view of space and time. Several issues are emphasized in the following 4 stages: task decomposition, service discovery and matching, service composition and optimization, adaptive adjustment. Meanwhile, some ideas and key technologies to solve related problems are given from the following three aspects: service selection method based on collaboration capability, two sided matching decision-making method of manufacturing service and adaptive decision-making method based on situation awareness.
