Sunto:
Emergency medical services (EMS) evolve in highly random and
dynamic contexts. Indeed, the arrival of emergency calls is
uncertain and varies throughout the day, forcing decision makers to
adapt their decisions in response to observed changes. Two types of
decisions are generally considered in real-time: dispatching and
relocation. Dispatching decisions consider the selection of which
ambulance to send to an emergency call. Relocation decisions consist
in relocating available ambulances throughout the day in response to
changes in the system state. Given the situation faced by EMS, the
analysis and development of real-time management strategies to
ensure a good service to the population is clearly of interest.
In a first study, several ambulance relocation strategies are
compared, and extensive simulation experiments are reported allowing
to analyze the performance of these strategies when they face
different level of system workload. Results of this study confirm
the relevance of simulation methods to support decision-making in
EMS stochastic environment. More importantly, they provide
researchers and decisions makers with valuable insights on the use
of relocation strategies, including the tradeoff between service
level and personnel well-being. In a subsequent study, an innovative
real-time ambulance fleet management strategy is proposed. New
mathematical models and solution approaches are then developed to
deal with both relocation and pre-assignment decisions. Preliminary
results show that considering explicitly pre-assignment decisions,
which are directly related to dispatching decisions, impact location
decisions and can help better predict system performances.
Cordiali saluti.
