  Title Workflows and decision tables for flexible early warning systems Type Conference Article

  Abstract Today's decision support systems for crisis management are mostly designed to support a fixed process that integrates a given set of information sources. This means policies that govern the crisis management process are tightly integrated with the implementation, which makes it hard to adapt the system to changing requirements. Modern systems are expected to be adaptable and need to evolve along with the availability of new information sources and changing business processes. Previous work suggested using workflow systems to manage crisis management processes. Current approaches that use workflow systems are not end-user friendly or not flexible enough. In this paper we present our approach that combines workflows and decision tables for creating more flexible decision support systems. While workflows are used to orchestrate services and implement information logistics in the decision support processes, embedded rule sets are used to provide flexibility and adaptability of workflows. The rule sets are authored using decision tables which are an easy-to-use representation that allows end-users to express rules in an intuitive way. © 2012 ISCRAM.

  Title The seven main challenges of an early warning system architecture Type Conference Article
  Year 2013 Publication ISCRAM 2013 Conference Proceedings – 10th International Conference on Information Systems for Crisis Response and Management Abbreviated Journal ISCRAM 2013  
  Volume Issue Pages 322-331  
  Keywords Decision support systems; Information systems; Middleware; Decision supports; Design decisions; Early warning; Early Warning System; Information sources; Simulation systems; System architectures; System-of-systems; Alarm systems  
  Abstract In this paper, we describe the work on the system architecture that is being developed in the EU FP7 project TRIDEC on “Collaborative, Complex and Critical Decision-Support in Evolving Crises”. One of the two decision support use cases in the project deals with Tsunami Early Warning. A modern warning system that follows a system-of-systems approach has to integrate various components and subsystems such as different information sources, services and simulation systems. Furthermore, it has to take into account the distributed and collaborative nature of warning systems. Working on the architecture of such a system, you need to deal with a lot of current computer science and information technology problems as well as state-of-the-art solutions from the areas of Big Data and Human Sensors. In this paper, we present the seven main challenges we needed to solve and describe the necessary design decisions we made to tackle them.
