關鍵基礎設施係為國家重要資產,多數皆彼此相依,元件之間存在有某種相依性,當其中發生損壞時,可能致其它元件損壞或導致連鎖效應。繼911恐怖攻擊事件後,國家安全成為重要課題,許多國家紛紛致力於關鍵基礎設施之研究,由相關發表文獻可知其關注。本研究係以文獻回顧的方式進行關鍵基礎設施投入產出停轉模型(Inoperability Input-output Model, IIM)的分析與研究,藉由文獻中了解IIM對於各種設施所造成的影響,回顧研究中模型量化的方法。透過文獻蒐集後整理出價值性較高的研究,進而篩選出值得回顧的文章,並藉由自然災害影響與人為災害(恐怖攻擊)影響的文獻作為案例,於不同的情況或環境下進行分析,並將IIM應用於關鍵基礎設施相依性研究當中,其結果表明關鍵基礎設施的相對重要程度將會隨著災害所造成的中斷而改變,其重要性與脆弱性皆大不相同。論文主要進行探討與文獻回顧,以助於瞭解IIM模型的確可以幫助我們在發生自然災害或人為因素影響下,於各個關鍵基礎設施相互影響後的可運行程度,對於關鍵基礎設施的風險管理之發展、完善防災救災的規劃,以及制定設施的修復與防範的策略,皆有重要的意義。本文將綜合重要相關文獻的公式剖析,逐漸將更多變因納入模組中,使得災害發生時,確切反映關鍵基礎設施救災之需求,致使系統可正常運行,進而提供後續發展與研究。The paper discusses the inoperability input-output model (IIM). The IIM is based on Leontief's input-output model, which characterizes interdependencies among sectors in the economy and analyzes initial disruptions to a set of sectors and the resulting ripple effects for modeling impacts of attacks on infrastructure interdependency. The IIM can systemically prioritize and manage the sectors deemed critical and also identify those sectors of which continued operability is critical during recovery. Discussion of modeling the physics of infrastructure and a disaster mitigation approach to stopping IIM-related possible future failure events is addressed, followed by the analysis results of sample infrastructure failure records. Disaster mitigation officials can employ the proposed approach to exploring IIM and designing countermeasures when a disaster hits certain areas.
