At present, cooperation between manufacturing enterprises is becoming important. Many manufacturing enterprises establish their own manufacturing resource domain ontologies. In order to achieve knowledge reuse and sharing among different manufacturing resource domain ontologies, the method of manufacturing resource domain ontology integration was introduced. Three cases-equivalence, parallel, and...
On the basis of analysis characteristics of some aerospace manufacturing enterprises, first, a new manufacturing resources organization model based virtual manufacturing cell (VMC) is introduced. Second, based on the ontology technology, manufacturing resource domain ontology is constructed. Then, the establish process and the formal definition of the domain ontology are given. Third, in order to...
The similarity computation for domain ontology is a critical problem. On the basis of analysis characteristics and functions of manufacturing resource domain ontology, a similarity computation algorithm for the manufacturing resource domain ontology is introduced. It depends on the process capability of manufacturing resource and is quite easier to understand. Then, two applications of this similarity...
In order to adapt to the requirements of manufacturing scheduling system in an aerospace enterprise, a new manufacturing scheduling system was put forward according to the actual situation of the aerospace enterprise, which plays a key role in manufacturing enterprises. And a new manufacturing resources organization model-manufacturing resources organization model based virtual manufacturing cell...
In order to reduce the time and cost of reconfiguration of manufacturing system, a new manufacturing resources organization model based virtual manufacturing cell (VMC) is introduced, So that the procedure of part task distribution and scheduling is simplified and the quality of the scheduling is improved. Then, the procedure of VMC formation is divided into two phases: resource selection and resource...
