Formal modelling and validation for software process based on CPN

Currently, many modelling methods for software process are semiformal. It is difficult to analyze semantics and verify correctness for a key system. Coloured Petri Net (CPN) based on mathematics is an executable model, which has rigorous formal semantics and analysis methods. This paper presents a method of formal modelling and validation for software process that transforms UML model based on RUP to CPN and uses simulation to investigate the behaviour of modelled system.
