The ambulance dispatchers are key players in any Emergency Medical Services (EMS) system, as they decide which ambulance to send to a patient. They are also responsible
for keeping the ambulances favorably positioned, and thus decide if the ambulances need to be relocated to better cover some parts of the area of responsibility. As the call
frequency and the fleet size grows, the complexity of these tasks increase exponentially.
Therefore, tools that can support the dispatchers in their decisions are vital for the effectiveness of the whole system.
In the OPAL project (Optimized Ambulance Logistics), SOS Alarm, Linköping University and Carmenta have collaborated to find new ways of making the ambulance health care in Sweden more effective. One result from the project was a number of optimization-based tools that support calculation and visualization of the preparedness
level, finding suitable resources and planning resource relocation. The new tools help the ambulance dispatchers make better decisions faster.
