Research on Mechanism and Measurement Model for the Effects of Path Dependence on Human Error in Space Station Manipulator Tasks

Abstract

Astronauts’ cognitive and operational processes are partly or absolutely influenced by the thinking and operation habits derived from a previous task or some tasks, which results in disturbance to human error—the disturbance may promote human error or inhibit human error. To explore the mechanism and measurement model of path dependence in human error, this study develops a method for judging the mode of the path dependence symmetric effect, and a mathematical symmetric model for quantifying the degree of the path dependence effect on human error is created. Taking the robotic manipulator teleoperation task as a study object, this study establishes a set of factors that influence the symmetric effect of path dependence, including facilitating or inhibiting human error, and identifies the relationships between these influencing factors. Based on questionnaire analysis, a fuzzy evaluation method for measuring the symmetric degree of the facilitating/inhibiting effect is obtained, by analyzing the simulation data, and the fuzzy method has good convergence, sensitivity and differentiation capabilities.
