- •
We develop a queueing network to model the interaction between an Emergency Medical Services (EMS) provider and regional hospitals.
- •
We investigate the effect of patient routing decisions on ambulance delays in front of the hospitals (offload delays).
- •
We develop an approximation scheme that can be used to find the optimal routing decision for a region that consists of one EMS provider and multiple hospitals.
