How Load Affects Service Times in Emergency Medical Services


We apply a general framework to analyze the influence of system load on service times in queueing systems to EMS systems. The framework unifies previous results and ties them to possible future studies to help empirical and analytical researchers to investigate and model the ways in which load impacts service times. We describe several mechanisms through which load induces behaviors in the servers, the users, or the network that cause the work content or the service speed to change. We test hypotheses related to the mechanisms using data from the Calgary EMS system. We discuss the implications our framework for empirical research on EMS operations.
