Collaborative, Complex, and Critical Decision Processes in Evolving Crises
• TRIDEC is a IT Research Project in the European Union’s Framework Programme
(FP7)
• New approaches and technologies for intelligent information management in
collaborative, complex and critical decision processes in earth management.
• This presentation focuses on the architecture developed for natural crisis
management (NCM) and the light-, mid- and heavyweight demonstrators for
Tsunami Early Warning.

Tsunami Early Warning Systems (TEWS)
TEWS are distributed software and hardware systems supporting
– reliable detection of imminent tsunami hazards,
– rapid situation assessment, and the
– targeted dissemination of customised warning messages.
TEWS infrastructures consist of
• national (National Tsunami Warning
Centre: NTWC); and
• regional warning centres (Regional
Tsunami Watch Centre:RTWC).

ICT Research and Development Strategy
Information and Communication Technology (ICT) view of
Tsunami Early Warning Systems:
• integrated software- and hardware systems for
• data acquisition,
• decision making and
• information dissemination, which
• support the detection and analyses of imminent hazards and the
dissemination of customised related warnings.

TRIDEC Architecture Overview
• The generic TRIDEC architecture
describes a common layout for the
sub-systems of a System of Systems
to interact via a communication
infrastructure.
• A communication infrastructure
based on a Message-oriented
middleware (MOM) enables
distributed applications and
distributed systems in heterogeneous
environments to communicate by
message exchange. Red triangles: SoS sub-systems with their own
data.

Remaining Work
• Extension of the System-of-Systems character (federation of distributed
components, international communication of systems)
• Integrate non-traditional tsunami signal detection approaches
• Leverage intelligent information management

The road ahead / ICT Megatrends
• Ubiquitous sensing,
• integration of Earth Observation (EO) systems,
• volunteered geographic information (VGI), and
• cloud computing
However, for any kind of early warning system, it will be critical to
prove that the range of functions can also be reliably offered as
cloud-based software services.

Conclusion
• Information and communication technology (ICT) has become the
driving factor for Tsunami Early Warning Systems (TEWS).
• IT concepts such as service-based architecture (SOA), system of
systems (SoS), middleware and semantic services enable standards-
based software infrastructures for national and regional TEWS.
• The TRIDEC software framework is used for local TEWS instances in
the North East Atlantic / Mediterranean (NEAM) region to be
connected in a system of systems.
