Modeling and verification of distributed real-time systems based on CafeOBJ

CafeOBJ is a wide spectrum formal specification language based on multiple logical foundations: mainly initial and hidden algebra. A wide range of systems can be specified in CafeOBJ thanks to its multiple logical foundations. However, distributed real-time systems happen to be excluded from targets of CafeOBJ. The authors propose a method of modeling and verifying such systems based on CafeOBJ, together with timed evolution of UNITY computational models.
