The design of a real-time system needs to incorporate methods specifically developed to represent the temporal properties of the system under consideration. real-time systems contain time and event driven actions. Structured design methods provided a reasonable set of abstractions for design of time and event driven factors in real-time designs. As program complexity, size, and time to market pressure grows, the real-time community migrated towards object-oriented technology. Evidence suggests that object-oriented technology in non-real-time systems is most effective in abstraction, modeling, implementation, and reuse of software systems. Many design models and methods exist for object-orientedreal-time designs. However, the selection process of a model for a particular application remains a tedious task. This paper introduces an analysis framework that can be applied to a design model to evaluate its effectiveness according to desired performance specifications. To illustrate our approach, we present a case study using the popular automotive cruise control example on two real-time object-oriented models. (C) 2002 Elsevier Science B.V. All rights reserved.

The problems associated with developing real-time software systems, including ensuring predictable real-time behavior under both normal and abnormal operating conditions, are outlined. The management of temporal complexity, structuring of dynamic real-time applications, object-orientedmodels, object-orientedreal-time languages, and the requirements for real-time object-oriented models are discussed. Chaos, an object-based language and programming/execution paradigm designed for dynamic real-time applications, is described
