“…Younes and Ayed [6] propose a set of rules for the translation of the activity diagram (AD) into Event-B language and how to use the refinement in Event-B to encode the hierarchical decomposition of activities in AD. But, they do not use Event-B and UML standards as well as do not show how to represent the system structural and static parts.…”

UML-B is a development process framework for Event-B based on a "UML-like" graphical formal notation that provides support for object-oriented modelling concepts, in particular, for class and state machine diagrams. However, this methodology has a gap for mapping requirements to formal specifications. To overcome this issue, we present a proposal for extending UML-B to support a conceptual model to provide an easier starting point for the actual development process. More precisely, we propose two diagrams to facilitate the passing from requirements to the initial formal model: a first one to represent system behavior based on UML 2 interaction overview diagram (IOD) and a second one for system structure based on boundary-control-entity stereotyped class diagram (BCE). We show how to translate the former into an Event-B specification and explain how to link the latter to the original UML-B using a simple ATM example as proof of concept.

“…On the other hand, we can use AD UML specifications as a tool to develop Event B specifications. In our works (Ben Jemni Ben Ayed, 2007,2008) , we have presented the translation process which uses the B method refinement and proposed translation rules for the basic concepts of UML AD (activity, Sequence of activities, choice (decision), loop parallel activities (fork and join) and atomic process) and also for dynamic invocations concept (Ben Younes and Jemni Ben Ayed, 2008) into Event B. In this paper, we discuss contribution of our proposed approach for the verification of workflow applications and we extend our work presented in (Ben Younes and Jemni Ben Ayed, 2007) by adding new translation rules for the synchronization in UML AD ( event, send/receive concepts) into Event B.…”

This paper presents a transformation of UML activity diagrams (AD) into Event B for the specification and the verification of workflow applications. With this transformation, UML models could be verified by verifying derived event B models, automatically, using the B powerful support tools like B4free. The workflows is initially expressed graphically with UML AD and translated into Event B. The resulting model is then enriched with Invariants/Assertions describing functional properties of workflow models such as deadlock-inexistence. We present translation rules of UML AD into EventB, and we propose also a translation process of UML AD into EventB specifications based on the refinement technique of Event B to encode the hierarchical decomposition in UML AD. Also, we propose a solution to specify time in Event B, and by an example of workflow application, we illustrate the proposed technique.

“…In our previous work (Ben Younes and Ben Ayed, 2008), we have proposed a specification and verification approach using UML activity diagrams (UML AD) to specify workflow applications and Event B to prove the correctness of the workflow. A workflow application is initially specified with UML AD.…”

In this paper, we propose an approach for the verification of workflow applications using AToM 3 and Event B. Workflow carries applications where many actors take part and cooperate in order to execute operations. Upon composing those operations, many problems such as deadlock, freeness and livelock might appear. In this context, we are going to show how to build a meta-model for UML activity diagram in AToM 3. From this meta-model, AToM 3 generates a visual tool to build and to specify workflow applications where syntactical verification is made. Further, we are going to define a graph grammar to generate a textual code from the graphically specified workflow. This code will maintain information about all the activities and their dependencies. Another role of the graph grammar is to generate an Event B machine used for the verification of the workflow. Structural errors like deadlock and absence of synchronization can be captured from the resulted Event B model. Functional requirements are also verified using the resulted Event B model.
