Modeling Requirement Driven Architecture of Adaptive Healthcare System Based on Semiotics

In order to improve the quality of healthcare services, the integrated large-scale medical information system is needed to adapt to the changing medical environment. In this paper, we propose a requirement driven architecture of healthcare information system with hierarchical architecture. The system operates through the mapping mechanism between these layers and thus can organize functions dynamically adapting to user´s requirement. Furthermore, we introduce the organizational semiotics methods to capture and analyze user´s requirement through ontology chart and norms. Based on these results, the structure of user´s requirement pattern(URP) is established as the driven factor of our system. Our research makes a contribution to design architecture of healthcare system which can adapt to the changing medical environment.
