STATE SPACE ANALYSIS OF THE GENERAL ANALYTIC MINEFIELD EVALUATION TOOL: IN PURSUIT OF THE ADVANCED UNDERSEA WEAPON SYSTEM

Naval mine warfare planning tools will grow increasingly important as maritime mines grow more sophisticated, permitting their use in less restrictive environments and for a wider variety of missions. The purpose of this study is to explore the state space of General Analytical Minefield EvaluationTool (GAMET) in order to evaluate simulation functionality and identify significant factors and interactions relevant to a traditional minefield and advanced undersea warfare system (AUWS) design. A design of experiments (DOE) is applied using a nearly orthogonal, nearly balanced Latin hypercube (NOB). A survey of the simulation is made to identify inputs and response variables. Two scenarios are created with justification of factor level settings and DOE process. A Visual Basic for Applications (VBA) user tool is developed to assist in creating files required to run 512 design points (DP) for the simulation to process. During the course of the study, GAMET simulated over 100 million transits, processing over 51,000 unique DPs. The analysis confirms that GAMET produces results consistent with real world experience and can be used to explore various AUWS designs. Metamodels based on regression analysis can be satisfactory for predicting number of casualties and detonations per transitor. These findings will advance AUWS design, help improve GAMET, and support broader GAMET usage within the Mine Warfare community.
