Abstract

Business processes modeling typically faces challenges in the integrated representation of processes’ lifecycle, informational, and organizational models. Despite the plethora of process modeling languages (workflow languages), studies on their expressiveness fail to identify a consensus on the languages and techniques to use. Consequently, some languages like LSAWfP, brimming with new techniques, continue to be proposed. LSAWfP relies on attributed context-free grammars to offer another perspective on process modeling with the goal of their decentralized execution. Preliminary studies on the expressiveness of LSAWfP demonstrate its support for process modeling cases generally supported by commercial solutions. However, these studies are insufficient as they only explore a small facet of LSAWfP’s expressiveness. This paper delves deeper into the expressiveness of LSAWfP by comparing it to the BPMN language, a domain standard. The comparative analysis between these two languages in this paper is conducted along three dimensions: control flow, data integration, and organizational structure. To leverage the theoretical studies in this paper, a foundation for a tool converting LSAWfP specifications into BPMN models is also proposed. The results of all these efforts further demonstrate that LSAWfP is a solution with significant operational and commercial potential.
