Selection of Human Working Conditions Based on Fuzzy Perfection

Abstract

A method for selecting the working conditions affecting the probability of human errors is proposed. The problem is reduced to comparing alternative scenarios each of which determines a set of concrete working conditions. The method is based on the idea of evaluating each working condition by the criterion of fuzzy perfection, i.e., the degree of proximity to a certain perfect condition, and on an integral evaluation of the scenario as a whole by intersecting fuzzy perfection sets of individual conditions. Fuzzy perfection membership functions, an algorithm for comparing alternative scenarios, and an example illustrating a comparison of the different working conditions of the crew of a vehicle are considered.
