Ambulance-initiated Dispatching by Centrality Principle in Emergency Medical Service

摘要

This research develops a plug-in that can be flexibly used along with various myopic rules in ambulance-initiated dispatching decisions that involve the selection of a call among those waiting when an ambulance gets freed. The idea behind this plug-in is to give a higher priority to the call that is more centrally located with respect to other calls. When the plug-in is used in conjunction with a myopic rule, the units would smoothly proceed towards dense regions whilst efficiently exploiting calls, thereby keeping the completion rate at maximum. This plug-in is tested in various scenarios and demonstrates considerable reductions in response time.
