Title: The fine line between life and death: Strategic location of automated external defibrillators
Automated external defibrillators (AEDs) are placed in public to decrease response time and increase survival rate from out of hospital cardiac arrest (OHCA). However, many AEDs are barely used due to poor location choices. In this study, we develop an algorithm that dynamically creates candidate AED locations and chooses near-optimal locations for new AEDs. The strength of the algorithm is that large instances can easily be solved since locations are created dynamically, keeping the problem size manageable while being able to evaluate a very granular set of candidate AED locations. We apply this methodology to a case study from North Holland and show that the coverage of OHCAs can improve by 73.5%.
