QUANTITATIVE MODELS FOR POLICY MAKING IN URBAN EMERGENCY NETWORKS.

Coordination between adjacent emergency networks in urban areas supported by various quantitative network models is considered. In operation and planning of these networks options are studied how to render and hire services between adjacent networks while each individual network maintains a certain degree of autonomy. In modelling, this would imply the devising of local optimal solutions which are subject to some coordination constraints (as opposed to global optimum which assumes merged networks). Some models of individual networks are reviewed and a coordination model recently developed is presented that takes into account aspects of charging for rendered services and improvement or deterioration of service quality due to the cooperation between the networks.
