工程弹性系统与系统弹性理论研究综述

工程弹性系统(engineered resilient system,ERS)是美国国防部(department of defense,DOD)应对越来越不确定的任务和环境而提出的未来国防系统发展战略,对复杂系统的工程实践与系统弹性理论都带来新的挑战。首先,对ERS提出的背景和相关概念进行介绍,重点对美国国防领域对ERS的一些观点进行分析,包括ERS的关键属性、弹性工程与现役系统关系、ERS设计中考虑的因素和ERS与系统工程的关系等,并对美国DOD优先立项的ERS项目研究进展进行了的研究。其次,对弹性相关的学术研究进行了述评,包括不同领域中弹性的概念、系统弹性不同的评价方法以及系统弹性设计方法,以便于对ERS的发展有一个较为全面的了解和借鉴。最后,在ERS发展研究基础上,从理论和应用角度对ERS和系统弹性理论面临的挑战进行了讨论。

Review of engineered resilient systems and system resilience theory

Engineered resilient system (ERS) is a future defense system development strategy proposed by the United States department of defense (DOD) in response to increasingly uncertain tasks and environments, which brings new challenges to the engineering practice and theory of system resilience. Firstly, this paper introduces the background of ERS, focusing on the perspectives of the DOD on ERS, which include the key attri-butes of ERS, the relationship between ERS and legacy system, the factors considered in ERS design and the relationship between ERS and system engineering. Secondly, the progress of ERS projects prioritized by the DOD is researched. Meanwhile, a literature review on system resilience theory is conducted, including system resilience definitions, assessment and analysis methods, in order to have a more comprehensive understanding of ERS. Finally, on the basis of the research on ERS, the challenges faced by ERS and system resilience theory are discussed theoretically and practically.
