Doctoral thesis abstract The main aim of this doctoral thesis is twofold, on the on hand, to research on the data modelling problem in a military environment and on the other hand, to analyze the most popular interoperability solutions for connecting command and control intelligence systems (C2IS) for adapting them to the large civil crisis management in which there are involved several emergency bodies (policemen, firemen, sanitary staff). In order to achieve this main objective the following researches and informatics developments have been performed. • An in deep analysis of the estate of the art of the data modelling problem for C2I systems in the military environment has been performed. This analysis starts with the firsts OTAN interoperability systems experiments. The Multilateral Interoperability Program (MIP) initiative has been analyzed with special interest. This analysis has allowed having a clear idea on the data modelling evolution in the military environment. This way a tendency and initiative pursuit on interoperability problems caused for data modelling problems has been done during the first part of the doctoral thesis. • Once the data modelling problem for C2I systems was analyzed in detail the following step in the doctoral thesis was the study of the coordination methods for huge civil crisis management. This study was focused on command and control problems and resource coordination gaps detected in some of the last real civil crisis, 11S attacks at NY city in 2001 and the Tsunami in the Indic ocean in 2004 • The more extended interoperability solution have been implemented a tested on the data models C2IEDM and J3CIEMD. With the obtained results a data model to be used in civil crisis management has been proposed and developed. • The proposed data model has been integrated in a blue force tracking system which will be able to be used for the different emergency bodies in charge of any civil crisis, terrorist attack, big flood, and so on. • The conclusions of this doctoral thesis reveal the current coordination lacks in the civil crisis management. This lacks can be improved with the inclusion of blue force tracking systems with real time communication and interoperability capabilities. By using this kind of systems a COP (Common Operational Picture) in all emergency bodies’ commanders is obtained. This way more accurate decisions can be taken in order to optimize the response time and the resource efficiency.
