A Manufacturing Service Resource Modelling and Dynamic Matching Algorithm Based on Domain Ontology

In order to realize the full-scale sharing and free transaction, and on-demand-use of manufacturing resource and capabilities in modern enterprise, networked manufacturing as a new service-oriented manufacturing paradigm has been proposed recently. Networked manufacturing paradigm is utilized to solve complex manufacturing issues, manufacturing and sharing services resources and large-scale collaborative manufacturing. As a key issue in the networked manufacturing, the dynamic matching algorithm for manufacturing service cell (MSC) and outsourcing manufacturing task (OMT) is becoming very important. Solving MSC and OMT dynamic matching problem with numerous constraints by using the traditional methods might be inefficient. In order to achieve fast, efficient and accurate MSC, this research tries to discover, match and optimized select OMT, establish the mathematical model, and describe the optimization process of MSC selection. To improve the searching efficiency further, full connection topology based on base on domain ontology to modelling MSC and OMT was adopted in the algorithm. In order to get the projection relationship between the processing needs of OMT and the capability of manufacturing resources, according to the relationship of manufacturing resources and information included in the manufacturing process, satisfaction model and matching model are constructed. The results demonstrate the effectiveness of the proposed method for matching complex manufacturing needs and manufacturing resources.
