Towards the agility of collaborative workflows through an event driven approach – Application to crisis management

Abstract

A B S T R A C TOrganizations are more and more involved into collaborations to face globalization, crisis situations or market demand. Consequently, they are strongly dependent on their collaborative processes and matching workflows, which have to be relevant and efficient through time. As collaborations and their context are now fast evolving, agility of collaborative workflows is now an unavoidable requirement. Several solutions have been developed to deal with this issue, but they often focus their monitoring on a single aspect of the collaboration and/or impose a single adaptation strategy to face the detected evolutions. This article describes a platform to support decisionmaking about the adaptation strategy to lead by: (i) taking into account and exploit relevant data gathered from the collaboration itself and its environment (context awareness); (ii) proposing relevant adaptation strategies to correct or improve the collaborative behaviour. Based on the solutions proposed by the platform, decisionmakers can choose the most appropriate adaptation tool to perform the selected adaptation strategy. As crisis responses are specific cases of collaboration in an unstable context of execution (short time to react, highly evolving environment), a proof of concept based on the Fukushima Daiichi nuclear disaster is developed to illustrate the use of the developed platform.

A new emergency decision support system: the automatic interpretation and contextualisation of events to model a crisis situation in real-time

“…Barthe-Delanoë et al [25], which followed the work of Lauras et al [22]. This particular study is evaluated in Table 3.…”

“…the information that must be retrieved during a crisis situation and cannot be retrieved beforehand: the emerging risks and incidents due to the crisis. Like Barthe-Delanoë et al [25], we use complex event processing to detect critical events and manage the 4Vs at the data level (see Table 3).…”

Real-time data exploitation supported by model- and event-driven architecture to enhance situation awareness, application to crisis management

“…A real event is anything that happens, is happening or will happen. Barthe-Delanoë et al (2018) also propose to use complex event processing, coupled with a mediation information system to model crisis, thanks to a dedicated meta-model proposed originally by Bénaben et al (2008). Here, the complex event processing is used to follow an ongoing crisis situation and detect major evolutions.…”

“…• Barthe-Delanoë et al (2018 propose to bridge the gap between systems and 'things that happens in the real world'. They propose to use an event-driven architecture that enables to retrieve both real-time and historical data.…”

“…• Barthe-Delanoë et al (2018 propose to receive events sent by heterogeneous sources, thanks to the OASIS Web services notification standard. As defined by Niblett and Graham (2005), these specifications define the protocol through which Web services can disseminate events.…”
