Abstract: Existed simulation works are always too dependent on a kind of particular techniques or tools to perform horizontal comparison and integration. There is no formal description for the simulation objects which leads to the lack of semantic support in the simulation. In order to guarantee the reusability and interoperability of heterogeneous models and services in satellite network simulation and provide verification support, a method based on ontology engineering is proposed. Based on the concept of simulation verification with semantic support, the purpose and requirements of applying ontology engineering in satellite network simulation are identified. A test is performed as to a specific simulation task, and the results show that, besides the semantic support, the former method can provide significant improvement in efficiency, which is over 200% in comparison with the latter one. It is concluded that it is quite feasible to apply ontology in the area of satellite network simulation.

Abstract: The process of Collaborative Product Development (CPD) comprises highly creative and knowledge-intensive tasks that involve extensive information exchange and communication among distributed teams. Traditional information management systems fail to provide adequate capability to support CPD, due to their inflexible data structures and hard-wired usage procedures, as well as their restricted ability to integrate process and product information. An ontology-based method of knowledge management is proposed to support CPD. The key idea hiding in the method is a flexible ontology-based schema with formally defined semantics that enables the capture and reuse of design knowledge. A part of CPD-oriented ontology library represented by UML is displayed.
