Quality of Service in Flexible Workflows Through Process Constraints

Hybrid business process modeling for the optimization of outcome data

“…This relation is done by means of a build activity, which provides the set of constraints for the specification of the pocket with a valid composition of workflow fragments. Although data is included in the activity-level constraints [64], these constraints no longer permit the activity functionality to be described nor the objective function to be optimized. A report in 2013 [76] shows that this research line, related to workflow technology, has been abandoned by the Sadiq et al research group.…”

From business process models to hierarchical task network planning domains

“…A correct process model is one without structural flaws, such as deadlocks, dead-end paths, incomplete terminations, etc. (Sadiq & Orlowska, 1997). A well-structured workflow is one in which each split control element (e.g.…”

Business Processes: Behavior Prediction and Capturing Reasons for Evolution

“…All of them assume prior knowledge of the structural changes due in the evolving workflow. Issues related to process quality of flexible workflows is addressed in (Sadiq et al, 2005a). In (Rinderle et al, 2005), the authors propose a case based reasoning approach to learning process evolution.…”

“…Today, workflows need to be flexible (Sadiq et al, 2005a;Sadiq et al, 2005b) in order to accommodate varying business process requirements and provide fast and reliable services. In addition, since workflow models are designed manually, they may not incorporate the complete set of business logics that drive the processes and, thus, often result in suboptimal service performance.…”

“…In our work, we consider workflow systems that follow flexible models, as described in (van der Aalst et al, 2003;Sadiq et al, 2005a). We propose a method for predicting the behavior (i.e., determine the future tasks) of a long running process instance, by analyzing the data stored in the workflow log of the corresponding process.…”
