A unified linear-time temporal logic solution to the steam-boiler control specification problem

The TLL XYZ/E is a formal language able to represent the dynamic semantics and the static semantics in a unified framework. It supports the whole process of program development, i. e. from the abstract specification to the efficiently executable program in a formal, precise and convenient way. the steam boiler control specification problem, a large case study in the fields of real time, hybrid and communication systems, is discussed with XYZ/E. The approach covers physical model construction, formal specification, stepwise refinement, verification, executable program and visual user interface programming.
