We propose a modeling method used in design space exploration of architectures of embedded systems. Modeling cost for performance evaluation tends to be too high for an architect to evaluate many architecture alternatives. Our method exploits a UML-based model transformation from an architecture expression to a simulation model to reduce the cost. A case study reveals that our method reduces the cost by more than a factor of 1/3 from that of manual modeling.

In software development projects, document artifacts have an important role as a form of communication. As a result, many documents are prepared and updated frequently in a large software system development project. In such a situation, it is difficult to analyze and review many documents manually. Recently, there are many researches for analyzing document artifacts by applying technologies such as document structure analysis, string analysis and natural language processing. In this paper, we review the works on document artifact analyisis technologies and their applications.
