The UML (Unified Modelling Language) state diagram notation is a graphical language which comprises an extensive set of constructs with good structural semantics but lack of a formal behavioural semantics. With this regard, we have used the Hoare's CSP (Communicating and Sequential Processes) to formalize the behaviour of UML SD. The fact that CSP is supported by model-checkers such as FDR enables a system design using a state diagram to be formally checked during design stage. This paper presents the formalization which would allow us to reason about the behaviour of a UML SD in CSP.
