Definition and Reuse of Analysis Patterns for Real-Time Applications

The analysis patterns improve the quality of products and the performance of development process. They have proven to be an effective means for capturing expert’s knowledge and reducing the costs and the time of development. In this paper, we are interested in defining analysis patterns to model both the functional and nonfunctional requirements of Real-Time (RT) applications. The motivation behind the definition of these patterns is to facilitate the modeling of RT applications that must meet not only the accuracy of results, but also the time constraints related to the validity of data and the deadline of transactions. The proposed RT analysis patterns are illustrated through the modeling of two RT applications examples: the road traffic control and the medical control applications. These patterns are supported by a CASE toolset that both helps in RT analysis patterns representation and guides the patterns reuse. Keywords— Real-Time applications; analysis patterns; functional and non functional requirements.
