A method of modeling human operator performance in complex systems, which is realized as a
DSS, is presented. It allows to conduct a detailed analysis of an operator’s performance to observe
the nature of his errors in the different stages of his control action: perception of a problem,
motivation for solving it, the evaluation of variants of a solution; then, making a decision, and its
implementation. The method provides a deeper analysis of underlying factors using the proposed
frame descriptions for errors with logical, decision-making, and classification algorithms, as well as
the results of psychological experiments. The specific feature of the suggested approach is that it
presents the opportunity to logically analyze errors and their underlying factors in the process of
collecting data on them, not by drawing conclusions from the investigation reports as the traditional
approach. The advantages of using the decision support systems for working with large amounts of
unstructured data, specifically in the process of identifying repeated errors and error-provoking
situations, are demonstrated.
