  • 摘要:

    体系(SoS)在遭受内部或外部的干扰时性能会受到影响,体系结构作为体系设计和构建的基础,其弹性不仅是反映体系性能恢复能力的一个重要指标,更是体系演化性的重要体现。提出了一种基于弹性的体系结构评价方法,对体系的组件或系统进行重要度分析(CIMs)。首先,给出了体系结构弹性的明确定义并构建了相关的数学模型,综合权衡了性能损耗与恢复时间对体系组件重要度的影响;其次,通过分析不同的干扰事件和恢复策略,构建了基于重要度分析的体系弹性优化模型,并重点分析了其对体系性能恢复的影响;最后,以某体系结构的弹性评价为例,对本文提出的模型和方法进行了验证,优化后的恢复策略使体系性能的恢复效率有显著的提高。
