Design and Verification of a Trustable Medical System

Developing an advanced medical informatics system is a grand challenge in the 21st century. In this paper, we construct and analyze a trustable medical system by Refinement Calculus of Object Systems (rCOS) in a model-driven development process. Our method greatly improves the dependability and efficiency of the complicate system. This implies that the formal techniques developed in rCOS can be integrated into a model-driven development process. For the verification, a tool, called UPPAAL, is used to ensure the safety and correctness of the medical system. Our result suggests a way to corporate design and verification in system development process.
