Information systems and Systems of systems
Research axes

There are three research axes in information systems and systems of systems:

System research axis

The aim of this research axis is the study of techniques, methods and tools for describing, analyzing and evaluating the systems. The themes addressed are:

• systems architecture and evaluation
• formalizing information exchange requirements
• formalizing regulations

• building conceptual models of information exchanges
• modeling (semi formal, formal) of systems and processes

• the study of the sharing and allocation of resources

• the study of networks of leave-behind sensors

• the validation of simulations

Information research axis

The aim of this research axis is the study of techniques, methods and tools for the description of, search for and exchange of information in a system. The themes addressed are:

• the study of automatic or semi-automatic annotation algorithms for documents and semi-automatic dimensioning algorithms for information

• construction and exploitation of ontologies

• study of meta-data for description of sensors, observations and data processes

• controlled reasoning through information sources

• information services, the search for and discovery of services

Fusion research axis

The aim of this research axis is the study of techniques, methods and tools for fusion data to build the most reliable representation possible of an observed situation. The themes addressed are:

• the study of classification algorithms, fusion of radar data, tracking (multi sensors, multi targets, passive tracking)

• sensor management (allocation of tasks and re-scheduling)

• passive location

• methods for fusion symbolic information

• the processing of distributed, uncertain, incomplete, more or less reliable information from diverse sources.
