Typical flowchart techniques lack constructs for expressing concurrency. Formal Verification of Business Processes as Role Activity Diagrams Amelia Badic˘ a˘∗ and Costin B˘adic ˘a† ∗University of Craiova, Romania, Email: ameliabd@yahoo.com †University of Craiova, Romania, Email: costin.badica@software.ucv.ro Abstract—Business process modeling is performed during the Activity diagrams describe the actual state of activities of a system by showing all the sequence of activities performed. We model sequential and concurrent activities using activity diagrams. Activity diagrams are very similar to state Diagrams because activities are the actual state of doing something. It captures the dynamic behavior of the system. Activity diagrams describe the actual work flow behavior of a system in Information Technology. Following is an example of an activity diagram for order management system. The OMG document on UML 2.0 proposes a Petri net based semantics for Activity Diagrams. Abstract Activity Diagrams can be used to describe internal processing as well as action-object flow. Since they do not focus on events and object interaction, it is not clear, how to combine them with the typical object-oriented diagrams like class and statechart diagrams. Role-activity Diagrams Modeling Based on Workflow Mining 2009 World Congress on Computer Science and Information Engineering Weidong Zhao, Anhua Wang, Xiaochun Fang @ Software School, Fudan University, Shanghai, China Weihui Dai @ Management School, Fudan University, Shanghai, China Presentation by Onur … 0000002291 00000 n While UML can seem complex for those less familiar with it, creating an activity diagram is a lot easier than it seems. )�7�J?���m�n��כ �� ղ:��#"��v| � `��4���b�>[@�� ]L�i�?�}��z��.��U��r���� �-�h~.����(L�]�UY�����LE���E�5ʍv�{� Tutorial 3: Use Cases and Activity Diagrams – Sample Solution (a) An activity diagram for the first part of the process. The Unified Modeling Language includes several subsets of diagrams, including structure diagrams, interaction diagrams, and behavior diagrams. These can be processes within a computer system, use case processes, or business processes. 0000001681 00000 n Title: Slide 1 Author: XPUser Created Date: 10/24/2012 8:42:53 PM "[2] Another site puts it even more simply: "Activity diagrams are used to illustrate activities. A Riva process model takes the form of a RAD. These diagrams describe the actual state of activities of a system by showing all the sequence of activities performed. According to Wieringa ([9]), an workflow We use the merge notation for such scenarios. 0000037194 00000 n Please select a specific construct below to read more about it or scroll down to see all.

Activity diagrams are suitable for specifying sequential or concurrent treatments. Activity diagrams can be drawn at different levels of formality, from a Basic Flow Chart style of diagram used to represent a simple Business Process to a sophisticated Action-based diagram that can be used to model a complex system.
