Experimental Investigation of Sketch Model Accuracy and Usefulness in a Simulated Tactical Decision Aiding Task.
Abstract
This report describes the implementation and experimental evaluation of a proposed decision aid to support naval Task Force Commanders. The decision aid, named the Sketch Model, enables a human operator to specify his subjective estimate of a multidimensional, multimodal, unsymmetric three dimensional function by electronically sketching its two-dimensional projection (e.g., iso-altitude contours of a three dimensional function) on a computer graphics terminal. The Sketch Model is hypothesized to have certain advantages over comparable decision aiding techniques (such as theoretical and empirical objective modeling and scalar subjective judgment). These advantages include ease, speed, and accuracy of estimation and of updating; consideration of qualitative data; and the capability of Bayesian estimation without explicit a priori data.
