    Ad-hoc management capabilities for distributed business processes
    (INFORMATIK 2010 – Business Process and Service Science – Proceedings of ISSS and BPSC, 2010) Zaplata, Sonja; Bade, Dirk; Hamann, Kristof; Lamersdorf, Winfried; Straßenburg, Daniel; Wunderlich, Benjamin
    Advanced business processes are mostly distributed and require highly flexible management capabilities. In such scenarios, process parts often leave their initiator's direct sphere of influence - while management requires both monitoring as well as instant reaction capabilities anytime during the overall execution of the process. However, realizing such functions is often difficult, e.g. due to the heterogeneity and temporal disconnectivity of participating execution systems. Therefore, this contribution proposes a two-tier concept for monitoring and controlling distributed processes by representing a process management system as a manageable resource according to the WSDM standard. Based on a minimal shared model of management capabilities it allows to define customized events and processing rules for influencing business processes executed on a remote (and even on a temporarily disconnected) process management system. Applicability is demonstrated by a scenario-based evaluation on distributed WS-BPEL and XPDL processes.

    Kontextbasierte Kooperation für mobile Geschäftsanwendungen
    (Wirtschaftsinformatik: Vol. 51, No. 4, 2009) Zaplata, Sonja; Kunze, Christian P.; Lamersdorf, Winfried
    Das Potenzial direkt nutzbarer lokaler Ressourcen ist für die Ausführung komplexer mobiler Anwendungsaufgaben oft nicht ausreichend. Basierend auf der kontextbasierten Kooperation ermöglichen daher so genannte mobile Prozesse, die Grenzen einzelner lokaler Systeme und somit die Restriktionen mobiler Geräte und ihrer speziellen Dienste zu überwinden. Durch die hierdurch erreichbare Kombination mobiler und stationärer Ressourcen kann so auch die zuvor nur eingeschränkt mögliche Ausführung individueller dynamischer und spontaner Aufgaben in mobilen Umgebungen verwirklicht werden. Dieser Beitrag stellt einen Ansatz zur Unterstützung mobiler Geschäftsanwendungen durch eine Infrastruktur zur kontextbasierten Ausführung mobiler Prozesse vor. Zudem werden wichtige Anforderungen für den Einsatz im Geschäftsumfeld identifiziert und entsprechende Systemerweiterungen zum Management der resultierenden Anwendungen diskutiert.AbstractRealistic requirements of mobile business applications often exceed the capabilities of their respective local environments. In order to overcome such restrictions of specific mobile devices, services, and resources, this contribution introduces the concept of context-based cooperation. It is based on mobile processes which enable applications to cross boundaries of individual systems and thereby allow combining both mobile and stationary resources in order to realize highly dynamic individual applications. This contribution presents an approach for realizing context-based cooperation built upon on a respective context management infrastructure and execution environment. It also identifies specific requirements and proposes related enhancements for mobile business applications.
