摘要：Ensuring absence of design model inconsistencies that may lead to errors creeping in software, is a major challenge of software development. Further, these errors may propagate to the different phases of software development life cycle models. Correct design rules help in developing consistent design models of software. A way to ensure the correctness of design models is through its validation. Validation of design models is based on validated design rules. This work proposes a method based on predicate logic for validation of design models. The method has been illustrated with the help of a verified case.
