Annotation for System Engineering of Large, Complex, Real-Time Systems

Abstract

The system engineering of large complex real-time systems is critical since it provides an integrated view and analysis of the system under design. However, to date, most methods and techniques have focused on the implementation aspects of real-time systems (hardware engineering, software engineering, human computer interaction). A number of methods exist at the system engineering level; however, they concentrate on the structure versus the attributes of the system. Computer aided software engineering (CASE) and system engineering tools tend to focus only on the structural aspects of the system as related to performance. Efforts, such as the IEEE Computer Base System Engineering (CBSE) Task Force are also currently concentrating on system design structure. However, in real-time systems, the design is also dependent on many other attributes. Current methods lack the ability to formal annotate and analyze factors which have nonstructural components.
