And materials data integration and control are one of core competences concerning with the development of mass data application in manufacturing enterprises.
In this paper, a context-aware materials data integration meta model is presented which is incorporating an advanced materials demand mapping and decomposition mechanism to support fine-grained materials data in the right time for the provision of materials services, based on the analysis of the application context involving the key points and relationships in their manufacturing processes.
Materials Data Context-aware Model Proper Data modeling is an essential task for providing an efficient and effective representation of the phenomena of interest.
Actually, this is the mechanism for obtaining first-order context information from raw materials data.
