Refinement of a Computer Simulation Model for Evaluating DAIS Display Concepts

Abstract

Previously reported application of Systems Analysis of Integrated Networks of Tasks (SAINT) to the Digital Avionics Information System (DAIS) was refined against extensive empirical data produced in man-in-the-loop experiments. The current work demonstrates the process of abstracting task characteristics from human performance data. Emphasis is shown to be required in the areas of the organization of the data, task representation, and threshold levels. Four specific experimental conditions, representative of a dual-task study, are reported along with the corresponding SAINT simulation performance predictions.
