CASIE is the brainchild of David Lovelock, M.J. Ebersole and the late John Bownds. Dr. Lovelock, of the University of Arizona, was the principal programmer of the software in the C-language. The program was designed to simplify most of the calculations related to managing a search emergency using modern search theory. CASIE also introduced innovative applications, like Resource Optimization and quantification of the Influence of Clues, as part of a comprehensive package of SAR analysis tools.

CASIE is provided free of charge, less any costs for reproduction or shipping, to the general SAR community in an effort to help save lives. SAR personnel interested in obtaining a copy of the software may purchase it at cost through the NASAR bookstore or download it free, with files in Zipped format.

CASIE III is a DOS based IBM compatible program that can be run on anything from an old XT to a Pentium. You won't believe how fast Resource Optimization works on any Pentium chip!

If you are a current user of CASIE III, you may want the recent updates to to the C6.lpb and E.lpb Lost Person Behavior profiles. The new E.lpb file includes data from the 1997 Koester/Stooksbury preliminary report on Alzheimers lost persons and the new C6.lpb file contains Tables for Search Managers from the 1995 Cornell/Heth report on "Distance Traveled in Urban and Suburban Walks by 3 to 12-year olds."
