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.

目标驱动系统弹性评估方法的发展

讨论了在外部影响条件下形成不同复杂度的对象的弹性指标的现有方法。说明了所讨论方法的优缺点。作为应用弹性概念的一般基础，指出了在特定时期内旨在实现某些预设目标的所谓目标驱动系统。建议使用由IB Russman的方法性仪器“实现目标的难度”构建的指标的值来定量评估类似系统的弹性。介绍了使用这种方法的计算方法和弹性评估模型的结果。基于所谓目标驱动系统行为的轨迹分析方法的应用，提出了Russman方法发展的方向，该方法通过积分指标表征研究对象的动力学来描述其速率和变化加速度坐标。关键基础设施动态走廊实现目标的难度复原力准则风险参考向量
