HSYS: A Computerized Methodology for Analyzing Human Performance in Complex Operational Settings

Abstract

This demonstration presents HSYS, a computerized methodology for analyzing human performance in complex operational settings. HSYS was developed in an attempt to better understand the interactional relationship between humans and operational systems (Hill, Harbour, Sullivan, and Hallbert, 1990) and to examine the many factors which influence Human-SYStem interactions. HSYS focuses on system interactions from the human's perspective and is built around a linear model of human performance, termed the Input-Action Model. The HSYS program automates much of the process of investigating human performance using Flowcharts based on the Input-Action Model. So far, HSYS has been designed and used primarily as an incident investigation tool. It is conceived, however, that HSYS might be useful as an analytical development tool where the Flowcharts would be used to examine whether all aspects that may influence human performance have been considered.
