Assisted generation of frame conditions for formal models
Philipp Niemann, Frank Hilken, Martin Gogolla, Robert Wille · Design, Automation, and Test in Europe · 2015
Modeling languages such as UML or SysML allow for the validation and verification of the structure and the behavior of designs even in the absence of a specific implementation. However, formal models inherit a severe drawback: Most of them hardly provide a comprehensive and determinate description of transitions from one system state to another. This problem can be addressed by additionally specifying so-called frame conditions. However, only naive workarounds based on trivial heuristics or completely relying on a manual creation have been proposed for their generation thus far. In this work, we aim for a solution which neither leaves the burden of generating frame conditions entirely on the designer (avoiding the introduction of another time-consuming and expensive design step) nor is completely automatic (which, due to ambiguities, is not possible anyway). For this purpose, a systematic design methodology for the assisted generation of frame conditions is proposed.
