Ambulance logistics comprises everything that has to do with managing an efficient ambulance health care, which includes both emergency medical services and patient transportations. In this work, ambulance logistics is defined and discussed using the Swedish public service enterprise SOS Alarm as a basis. A number of ways of improving the ambulance logistic service provided by SOS Alarm are identified, and nine areas of improvement are defined. Two of the nine areas, -Visualisation of the preparedness- and -Decision support for efficient ambulance logistics- are described in more detail. In both of these, the main improvement lays in the development of decision support tools for the ambulance dispatchers. The tools that are developed are a preparedness calculator, an ambulance dispatch suggestion tool, a relocation tool and a simulation tool.
