Abstract: Aiming at the problems that knowledge resource can't be configured on demand and the ability of precise push is deteriorating in the process of complex product R&D under cloud mode,a service behaviour model of multi-dimensional knowledge resource cloud collaboration was established by using ontology-based directed acyclic graph and collaborative workflow based on the analysis of knowledge resource composition and service requirements.In this model,directed acyclic graph was used to establish the logical relationship between multi-granularity knowledge resources to form knowledge cloud droplets and clusters corresponding to specific R&D links,and the mapping relationship between knowledge clouds was described through multi-domain ontology to form the knowledge cloud system of product R&D process.According to the characteristics of multi-task cross-process collaboration in the process of complex product development,the implementation mechanism of multi-dimensional knowledge resource cloud collaboration service based on task flow-resource-state-rule was established,and the accurate push of knowledge resources was completed.The implementation framework of multi-dimensional knowledge resource cloud collaborative service was built in the process of large blade R&D,which provided the realization method and approach for precise pushing of knowledge resources in the process of complex product R&D.
