Abstract:

This thesis evaluates the usability of THORN a system for displaying a discrete event simulation model in a geographic information system. THORN was developed to enhance the planning phase of Operational Maneuver from the Sea. The goals of this study were to test the system against usability criteria and provide a benchmark for future testing. The purpose of this analysis was to 1. create a system for viewing discrete event simulations fused with geo-referenced spatial information 2. determine the systems usability 3. identify problem areas in the graphical user interface, and 4. provide a proof of concept for incorporating usability in the design of military planning tools. The studys scenario is based on the principles outlined in the white paper Operational Maneuver from the Sea. The study tested whether THORN met the usability objectives of a. 90 successful tasks completion b. ease-of-use ratings of somewhat easy or better, and c. satisfaction ratings of somewhat satisfied or better. THORN met all of these usability objectives.
