1 - Event Correlation in Non-Process-Aware Systems

Since business processes supported by traditional systems are implicitly defined, correlating events into the appropriate process instance is not trivial. This challenge is known as the event correlation problem. This paper presents an adaptation of an existing event correlation algorithm and incorporates it into a technique to collect event logs from the execution of traditional information systems. The technique first instruments the source code to collect events together with some candidate correlation attributes. Secondly, the algorithm is applied to the dataset of events to discover the best correlation conditions. Event logs are then built using such conditions. The technique has been semi-automated to facilitate its validation through an industrial case study involving a writer management system and a healthcare evaluation system. The study demonstrates that the technique is able to discover the correlation set and obtain well-formed event logs enabling business process mining techniques to be applied to traditional information systems.

2 - A proposal on service execution measures for the improvement of business processes realized by services

The realization of business processes (BPs) by means of services provides the basis for separating their definition from the technologies that implement them. Services can implement an activity, a sub-process or a complete BP, and can be integrated easily into the BP execution without the interoperability problems that had to be solved formerly for systems to achieve integration. A key aspect for the improvement of BPs is to measure their real execution to assess whether they are performing as expected, including the services realizing them. We have defined a BP Execution Measurement Model (BPEMM) in the context of MINERVA framework for the continuous improvement of BPs, which provides execution measures for BPs implemented by services. In this paper we present our vision for the measurement of services execution -for internal and external services- invoked from BPs.

5 - Predicciones en Procesos de Negocio Declarativos

La generación de predicciones sobre instancias de procesos de negocio permite anticipar problemas, evitar el incumplimiento de restricciones de una manera proactiva, y tomar decisiones sobre prioridades y restricciones al enfrentarse a eventos inesperados, e.g., retrasos. Sin embargo, elaborar una predicción es una tarea compleja en la mayoría de los casos ya que se deben tener en cuenta múltiples instancias y recursos, es necesario adaptar dichas predicciones a circunstancias cambiantes, y hay que tener en cuenta distintas dimensiones, no sólo el tiempo. En este contexto, el presente trabajo propone una propuesta novedosa para generar predicciones sobre un conjunto de instancias en ejecución relacionadas con un modelo declarativo de un proceso de negocio. Dicha propuesta consiste en generar un plan de ejecución optimizado a partir del modelo declarativo y del estado de las instancias en ejecución. Tras ello, la predicción se genera evaluando la función que se desea predecir sobre el plan de ejecución generado. La presente propuesta ha sido evaluada utilizando un modelo de proceso de un escenario real que incluye restricciones temporales, de datos, de recursos y de control-flow que lo dotan de una alta complejidad. Los prometedores resultados obtenidos alientan a continuar los trabajos en escenarios con características diferentes que permitan extender la validez de la propuesta.
