Abstract:

In order to realize manufacturing resource sharing which oriented to cloud manufacturing service chain construction driven by time and sequence constraint tasks, a kind of integrated service mode with the features of wide-area integration and distributed service was set up, which could promote rapid sharing and high utilization rate of resources in cloud manufacturing environment. Then some key technologies were studied, including cloud manufacturing task and resource model based on semantic ontology, cloud manufacturing resource service encapsulation scheme based on web service resource framework, cloud manufacturing task decomposition and atomic task chain construction, cloud manufacturing resource service chain construction. Based on the key technologies, some problems such as heterogeneous resources description and their virtualization, retrieval and matching, service combination were resolved effectively. Finally, service mode and realization technology were verified through a simulation example.

Key words: cloud manufacturing, manufacturing task, resource service chain construction, resource sharing
