A step towards merging xUML and CSP ∥ B

Much research work has been done on linking UML and formal methods but few have focused on using formal methods to check the integrity of the UML models so that the models can be verified. In this paper we focus on executable UML and on the issues related to concurrent state machines. We show that one integrated formal methods approach, CSP || B, has the potential to be tailored to support reasoning about concurrent state machines and in turn expose any weaknesses in the UML model. We identify future avenues of research so that a system methodology based on executable UML can be enhanced by formal reasoning

A Step towards Merging xUML and CSP||B

Much research work has been done on linking UML, and formal methods but few have focused on using formal methods to check the integrity of the UML models so that the models can be verified. In this paper we focus on executable UML and on the issues related to concurrent state machines. We show that one integrated formal methods approach, CSP parallel to B, has the potential to be tailored to support reasoning about concurrent state machines and in turn expose any weaknesses in the UML model. We identify future avenues of research so that a system methodology based on executable UML can be enhanced by formal reasoning
