From Requirements to Code: Model Based Development of A Medical Cyber Physical System?

The advanced use of technology in medical devices has improved the way health care is delivered to patients. Unfortunately, the increased complexity of modern medical devices poses challenges for development, assurance, and regulatory approval. In an eort to improve the safety of advanced medical devices, organizations such as FDA have supported exploration of techniques to aid in the development and regulatory approval of such systems. In an ongoing research project, our aim is to provide effective development techniques and exemplars of system

Cyber-Physical System Requirements - A Model Driven Approach

Systems where the physical world interacts extensively with often distributed and networked-software are referred to as Cyber-Physical Systems (CPS). Gathering and analyzing CPS requirements poses unique challenges to the requirements engineering community - a perspective that is sensitive to the scoping and interplay between the cyber, physical and behavioral aspects of the system.

Modeling and Requirements on the Physical Side of Cyber-Physical Systems

In a cyber-physical system (a system where the physical world interacts extensively with—often networked— software), the physical portion of the system resides in the continuous and continual domain. Thus, on the physical side of cyber-physical systems we will have to contend with not only real time requirements but also the continuous and continual nature of the system.
