Abstract: To solve resource discovery problem in cloud manufacturing environment,the information model and the model construction method of manufacturing resources and tasks were studied.Resource discovery mechanism was proposed based on ontology technology,and resource matching rules was defined from three aspects of function structure,attribute constraints and service status.Furthermore,description logic was used to express those matching rules.A resource discovery framework was put forward,which comprised of resource layer,agent layer,knowledge layer and user layer.Knowledge-reasoned automatic resource discovery was realized through the integration of information model and matching rules.Gear manufacturing was taken as an example to describe the process of resource discovery.

Key words: cloud manufacturing, resource discovery, information model, ontology
