Abstract
Existing approaches to formation of quantitative indicator of resilience of objects of different complexity operating under conditions of external impacts are discussed. Advantages and disadvantages of approaches under discussion are specified. As general basis for application of resilience concept, the class of so-called target-driven systems oriented to achieving some preset target in a certain period is marked out. It is proposed to use the value of the indicator constructed using methodical apparatus "difficulties of achieving target" of I. B. Russman for quantitative assessment of resilience of similar systems. Methods of calculation and results of model assessments of resilience using this approach are presented. Directions of Russman’s approach development are proposed based on application of so-called method of trajectory analysis of behavior of target-driven systems, described by dynamics of integral indicator characterizing object of study in coordinates of rate and acceleration of its changes.
Highlights
The term "resilience" began to be used in scientific publications in the late 1990s. Initially it was applied in rather narrow areas of psychology and ecology and was primarily related to recoverability (rehabilitation) of a person or natural ecosystem after stressful situation
The difficulty of achieving targets is considered as a variable value, inverse to resilience, and representing itself a function relative to the current position of the indicator: it increases as the value of the indicator approaches some permissible boundaries, after which it is impossible to reach the target value
Proposed combination of methods of analysis of the current state of target-driven system makes it possible to solve tasks of assessing the efficiency of its functioning aimed at achieving the target and quantifying its resilience from system position
