We present an integration of Z and timed CSP called RT-Z, incorporating the strengths of both formal languages in a coherent frame. To cope with complex systems, RT-Z is equipped with structuring constructs built on top of the integration, because both Z and timed CSP lack appropriate facilities. For RT-Z to be built on formal grounds, a formal semantics is defined based on the denotational semantics of Z and timed CSP.
RT-Z is intended to be used in the requirements and design phases of the system and software development process. The envisaged application area is the development of real-time embedded systems.
