In the real-time systems, designers typically focus on designing a functionally correct system. They later test it for its timing performance. Therefore, errors due to overloaded resources are exposed very late in the development process, and often at run-time. In this case, there will be many fine tunings and rewrites, making the system increasingly more difficult to understand, maintain, and extend. Indeed, in the object-oriented model, developers must retrieve and understand the object interdependency timing behavior, to analyze and rearrange the code. In order to help achieve schedulability, we propose an alternative to this painful process, which extends previous solutions, to deal with the real-time object model. We apply the concept of dependency analysis to the object-oriented model of the real-time task, that we restructure in a way to enhance the global schedulability.
