Deadline-based escalation in process-aware information systems
Decision making in process-aware information systems involves build-time and run-time decisions. At build-time, idealized process models are designed based on the organization's objectives, infrastructure, context, constraints, etc. At run-time, this idealized view is often broken. In particular, process models generally assume that planned activities happen within a certain period. When such assumptions are not fulfilled, users must make decisions regarding alternative arrangements to achieve the goal of completing the process within its expected time frame or to minimize tardiness. We refer to the required decisions as escalations. This paper proposes a framework for escalations that draws on established principles from the workflow management field. The paper identifies and classifies a number of escalation mechanisms such as changing the routing of work, changing the work distribution or changing the requirements with respect to available data. A case study and a simulation experiment are used to illustrate and evaluate these mechanisms.
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
