To the Question of Evaluating Criticity of Elements of Ergatic System

Abstract

The paper presents a scientific and methodological approach that allows to formalize the definition of the reliability of the ergatic system by determining its critical elements. The proposed approach is based on a matrix method for determining the performance of a complex ergatic system. The integral index is a numerical expression of the system performance. Calculating it for all the different variants of placing the «source» of the system operation allows you to identify the most critical elements to ensure maximum performance. The actual dependence of the value of the integral index of the system on the initial graph of its functioning is shown on a specific example.
