Origin and development of resilience engineering: a perspective on safety engineering

Abstract

Resilience engineering has been a hot topic in safety engineering. Traditional safety engineering methods, including component-based safety engineering approaches and system safety engineering approaches, focus on maintaining systems in a safe state, in particular aiming to maintain systems to be reliable and robust. However, resilience cannot be absent from safety out of many recent disasters that occur in society. This paper summarizes the origin and development of resilience concept in different disciplines and corresponding definitions in these different contexts. The definition of resilience engineering is further discussed by presenting the evolution of safety engineering, followed by a brief review of methods used to measure and enhance the resilience of a system. Conclusions as well as the limitations of current literature are also discussed in the last section.

彈復性工程已經成為安全工程領域的一個熱點方向。傳統安全工程方法,包括基于組件的安全工程方法和系統安全方法,專注于保持系統處于安全狀態,包括可靠性和魯棒性。然而,近來的很多社會災害表明在考慮系統的安全問題時,彈復性不能被忽略。概述了彈復性概念在不同的學科的起源和發展,以及相應背景下的定義。進一步通過總結安全工程的演化討論了彈復性工程的定義,以及用于評估和提升系統彈復性的方法。最后進行總結并討論了當前文獻中的不足。
