Algorithms for Decision Aid for Risk Evaluation (DARE) version 2.1. NURC-FR-2006-002. April 2006.
Decision Aid for Risk Evaluation (DARE) is a software tool for assessing the risk to transiting vessels after Maritime Mine Countermeasures (MCM) have taken place. The DARE software has been used in NATO Exercises since 1997. The software has been updated and improved to reflect the needs of the NATO navies. In order to estimate the risk to naval traffic, DARE uses information on the mines countered during MCM Operations, along with the "percentage clearance," or the probability estimate of having countered any given mine. DARE is a command level tool developed to provide an estimate of risk in the case where there may be several units working together and where the mine threat cannot be attributed to a single mine type. Another NATO software tool, MCM EXPERT, can be used to assist units in Planning and Evaluating tasks, and to provide the percentage clearances required by DARE. The NATO Undersea Research Centre has been responsible for the previous two versions of DARE. Version 2.0, released in May 2004, was entirely revised from the previous release (DARE98) and included a new Graphical User Interface, an updated algorithm, and an optimized calculation method which greatly increased the size of scenarios that could be calculated. DARE version 2.1 was released in December 2005. In addition to new software functionality, this version has additional algorithms which can be used to handle the case of multiple transitors. This document provides a comprehensive treatment of the algorithms used in DARE version 2.1.
