Generic Methodology for Formal Verification of UML Models

This paper discusses a Unified Modelling Language (UML) based formal verification methodology for early error detection in the model-based software development cycle. Our approach proposes UML-based process utilising functional and behavioural modelling artifacts of UML. It reinforces these with model transition property verification. The main contribution is UML to Labelled Transition System (LTS) Translator application that automatically converts Statecharts models. Property specifications are derived from system requirements corresponding Computational Tree Logic (CTL)/Linear Temporal (LTL) checking procedure verifies entailment LTS. With its ability verify CTL LTL specifications, becomes generic verifying all types embedded behaviours. steep learning curve associated methods avoided through automatic generation thus reduces reluctance using projects. A case study an controller used military applications validates methodology. establishes how finds use correctness consistency models before implementation.
