Workflow Patterns for Business Process Modeling

For its reuse advantages, workflow patterns (e.g., control flow patterns, data patterns, resource patterns) are increasingly attracting the interest of both researchers and vendors. Frequently, business process or workflow models can be assembeled out of a set of recurrent process fragments (or recurrent business functions), each of them having generic semantics that can be described as a pattern. To our best knowledge, so far, there has been no (empirical) work evidencing the existence of such recurrent patterns in real workflow applications. Thus, in this paper we elaborate the frequency with which certain patterns occur in practice. Furthermore, we investigate completeness of workflow patterns (based on recurrent functions) with respect to their ability to capture a large variety of business processes

Business Process Model for Interoperability Improvement in the Agricultural Domain Using Digital Twins

A farm generates a lot of data from various systems, which is then stored in a distributed manner, usually in non-standardized formats, which bears the risk of data inconsistencies. This work addresses this issue by using business process management (BPM) to demonstrate that the use of digital twins (DTs) can improve interoperability between services in the agriculture domain. Steps from the BPM lifecycle were applied to a farming use case in Germany. First, the as-is business process model was discovered and modeled without DTs, analyzed and then redesigned into the to-be model according to the DT integration. The to-be model showed a reduction in the number of tasks needed to be performed by the farmer as well as an improvement of process data quality, interoperability, and efficiency. Finally, a comparison of the\u27 average processing times of both models with the help of process simulation revealed improvements in the to-be process

A Distributed Repository for Managing Business Process Models in Cross-Organizational Collaborations

Cross-organizational collaborations require the management of models for: collaborative business processes (CBPs), which define the collaboration´s behavior; and integration business processes (IBPs), which define the behavior that supports the role an organization performs in a CBP. Managing these business process models becomes a complex task when organizations integrate collaborative networks and set up several cross-organizational collaborations. This paper presents a distributed repository that provides the functionalities required to manage conceptual business process models involved in cross-organizational collaborations. A service-oriented architecture is proposed for the distributed repository. This architecture enables organizations to access a global repository for managing collaborative networks, cross-organizational collaborations, and their CBP models. Organizations can also maintain local repositories of IBP models, which are synchronized and consistent with CBP models, while preserving their private aspects. By using verification methods and a model-driven architecture method, the distributed repository provides services that support the synchronization, consistency and interoperability requirements for CBP and IBP models. A case study is presented along with an implementation of the distributed repository.Fil: Lazarte, Ivanna Maricruz. Universidad Tecnologica Nacional.

An Experiment to Analyze the Use of Process Modeling Guidelines to Create High-Quality Process Models

Process modeling guidelines are an essential tool to help process modelers to create models that are correct and easy to understand. Many guidelines have been proposed in the literature, but there is little empirical evidence to which extent guidelines are effectively used. This paper addresses this research gap by presenting the results of a semi-controlled experiment conducted on two occasions with 21 students from a Business Process Management course. Two successive process modeling tasks were compared, one before and one after the subjects were presented to a set of 20 guidelines, which were collected through a systematic literature review. From the results obtained with the experiment, it was observed that the subjects would be more receptive to the guidelines if they were easier to understand and use
