The five chapters of the first section serve to introduce the major issues in modeling real-time systems.
Chapter 1 examines the historical phases of systems development, and shows that developing real-time systems is becoming a discipline dominated by the problem to be solved rather that by the technology used in the solution.
Chapter 2 gives the characteristics of real-time systems, thus describing the systems within the scope of this book. On-line interactive systems are not discussed, although the tools and techniques described herein can be applied to such systems.
Chapter 3 describes the requirements for a system modeling language for real-time systems.
Chapter 4 introduces the idea of modeling heuristics — rules of thumb ...
