Abstract

Optimizing Search Strategies through Application of Operations Research and GISystems
Track: Fire, Rescue, and EMS

As with most emergency response, Search and Rescue (SAR) is time sensitive. Delays in locating a lost subject impact survivability as they may succumb to the environment or injury, as well as allowing a mobile subject to expand the search area. Clues such as discarded objects, footprints and scent deteriorate over time reducing the likelihood of discovery. Additionally placing teams in the field requires some level of risk exposure. Given the large areas and often lack of readily available resources, it is imperative to optimize effort allocation.

In recent years, Operations Research has been adopted by the WSAR community as a means of improving decision-making and efficiency. As WSAR is an inherent geospatial problem, coupling this process with GISystems analysis further enhances effectiveness. This study demonstrates the applicability of GIS to provide an improved estimate of the probability density distribution and effort allocation during search operations.
