- ZeitschriftenartikelRepairing Alignments of Process Models(Business & Information Systems Engineering: Vol. 62, No. 4, 2020) Zelst, Sebastiaan J.; Buijs, Joos C. A. M.; Vázquez-Barreiros, Borja; Lama, Manuel; Mucientes, ManuelProcess mining represents a collection of data driven techniques that support the analysis, understanding and improvement of business processes. A core branch of process mining is conformance checking, i.e., assessing to what extent a business process model conforms to observed business process execution data. Alignments are the de facto standard instrument to compute such conformance statistics. However, computing alignments is a combinatorial problem and hence extremely costly. At the same time, many process models share a similar structure and/or a great deal of behavior. For collections of such models, computing alignments from scratch is inefficient, since large parts of the alignments are likely to be the same. This paper presents a technique that exploits process model similarity and repairs existing alignments by updating those parts that do not fit a given process model. The technique effectively reduces the size of the combinatorial alignment problem, and hence decreases computation time significantly. Moreover, the potential loss of optimality is limited and stays within acceptable bounds.
- KonferenzbeitragService-Oriented Architecture for Knowledge-enriched Workflows Modelling and Execution(Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Vidal, Juan C.; Lama, Manuel; Bugarín, AlbertoThis work presents a Service-Oriented Architecture that supports the man- agement, execution and monitoring of knowledge-enriched workflows. This archi- tecture is based (i) on a framework that allows the specification of workflows from knowledge components; and (ii) on the interfaces that are defined in the workflow reference model proposed by the Workflow Management Coalition.
