Abstract

Modern Information and Communication Technology open a door for innovations that can improve the functioning of companies. Many innovations can come from the analysis of business processes. Today modeling is widely used for the analysis of business processes. In these work we propose a process modeling technique based on role modeling. To specify a process where one business object may play several roles, a synthesis operation (the composition of two base roles in a third role) has to be specified. All role-based techniques have difficulties specifying role synthesis: synthesis is never specified without the description of actual messages passing between business roles. Such implementation details complicate the understanding of the model and semantics of synthesis become implicit. To specify a business process of a complex system at a higher level of abstraction requires the proper understanding of relationships between roles, when they are put together in one common context. In this paper we define the concept of synthesis constraints that shows relations between roles. Using synthesis constraints allows a business modeler to make explicit his decisions about how the synthesis is done in an abstract and implementation independent way. This approach can be used for building a BPR case tool that enables the discovery of new business processes by means of different disassembling and assembling of roles.

Business process modeling
Business process modeling (BPM) in business process management and systems engineering is the activity of representing processes of an enterprise, so that the current business processes may be analyzed, improved, and automated. BPM is typically performed by business analysts, who provide expertise in the modeling discipline; by subject matter experts, who have specialized knowledge of the processes being modeled; or more commonly by a team comprising both. Alternatively, the process model can be derived directly from events' logs using process mining tools.
Business Process Model and Notation
Business Process Model and Notation (BPMN) is a graphical representation for specifying business processes in a business process model. Originally developed by the Business Process Management Initiative (BPMI), BPMN has been maintained by the Object Management Group (OMG) since the two organizations merged in 2005. Version 2.0 of BPMN was released in January 2011, at which point the name was amended to Business Process Model and Notation to reflect the introduction of execution semantics, which were introduced alongside the existing notational and diagramming elements.
Business process
A business process, business method or business function is a collection of related, structured activities or tasks performed by people or equipment in which a specific sequence produces a service or product (serves a particular business goal) for a particular customer or customers. Business processes occur at all organizational levels and may or may not be visible to the customers. A business process may often be visualized (modeled) as a flowchart of a sequence of activities with interleaving decision points or as a process matrix of a sequence of activities with relevance rules based on data in the process.
