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.
