Abstract: This paper proposes a categorical foundation for integrating various types of manufacturing knowledge in manufacturing systems. The composing procedures of overall system can be explained by pushout of category theory. The purpose of this paper is to resolve the issue involves in sharing and coordination for modeling knowledge application in distributed manufacturing systems. We will propose a method for modeling discrete event system. The mathematical foundation lies in assuring that the constructed models have mathematical properties, e.g. consistency and completeness, and overcome the drawbacks of traditional function models, since it can show not only the static structure but also the dynamic semantics. The categorical notations and properties are expressed by an example of flexible assembly workcell.

Abstract: Manufacturing grid (MG) is the application of grid technology in networked manufacturing. Ontology has been considered as an important theoretical basis in many areas such as information integration, semantic web and knowledge management. The descriptions on manufacturing tasks are usually vague, incomplete and inconsistent in industry. MG task model and its semantic description method are the foundation and guarantee of quality of service (QoS) in MG. The MG task model is presented. The combination of ontology with MG study, in terms of analyzing basic classes in MG, and basic ontology classes, requirement model of service capacity of MG task are proposed. According to the description model of service capacity, the semantic description method for MG tasks is put forward.
