Timeliness is essential in real-time systems, in which a late response is sometimes worse than no response at all because the violation of a single deadline could lead to loss of life or property. System analysts use an appropriate scheduling algorithm to ensure the predictability of such a system. The Object Management Group's adoption of the UML profile for schedulability, performance, and timeliness has increased interest in using UML and object-oriented technology to model and implement real-time systems. Rate monotonic analysis (RMA) is an extensively researched and successfully implemented technique that can be used in conjunction with the UML profile to analyze schedulability in these systems.
