When multiple emergency calls occur, response times to multiple emergency incidents may increase due to the lack of fire engines with appropriate equipment and/or associated fire crews to handle more than one emergency call simultaneously. This presentation discusses a data-driven and scientific approach to assist in decision making process related to the preemptive reallocation of fire engines (and associated fire crews) in a fire department where multiple fire or other emergency incidents is expected to occur concurrently in a fire district for a limited time window. The preemptive reallocation of fire engines refers to the systematic reallocation of a secondary fire engine and associated fire crews to a certain fire district in order to respond to multiple incidents more efficiently by maximizing the use of existing emergency response resources. The preemptive reallocation tactic is particularly useful for a small municipality where they lack the operating budget to create and maintain large-scale emergency response resources.
