Business process verification - finally a reality!
The goal of this paper is to demonstrate that process verification has matured to a level where it can be used in practice. Earlier techniques assumed simplified process models without the more advanced constructs available in today’s modelling languages (e.g., cancellation and OR-joins). This paper reports on new verification techniques that can be used to assess the correctness of real-life models. The proposed approach relies on using formal methods (i.e., mapping a business model to a reset net which is an extension of Petri nets, and performing state space analysis) to determine the correctness of business processes with cancellation and OR-joins. The paper also demonstrates how reduction rules can be used to improve the efficiency. We present these techniques in the context of the workflow language YAWL that provides direct support for 20 most frequently used patterns found today (including cancellation and OR-joins). But the results also apply to other languages with these features (e.g., BPMN, EPCs, UML activity diagrams, etc.). We have developed an editor that provides diagnostic information based on the techniques presented in this paper.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
