Optimal Navigation of First Responders Using DBMS

摘要

Decision-makers in crisis situations must be aware of the positions of all emergency response units (fire brigade,paramedics,police and municipality).Since the locations of first responders may change frequently,they are referred to as moving objects.The locations of moving objects can be continuously recorded and dynamically visualized (a service available also in command and control software),but limited attention is given to real time analysis and simulation.Dedicated software (usually available for one emergency sector and even for a specific region) allows for more elaborate route calculations,taking into account traffic jams and street blockings,but computations are usually completed for one vehicle and on a predefined road network.In large emergencies,much more complex questions must be answered,such as 'which ambulance is closer to the place of incident,' 'how can we send three fire trucks to the place of incident most quickly,' and 'what is the closest meeting point.' This papa-reports the initial results of complex analysis in a Database Management System (DBMS).
