關鍵基礎設施為實體或非實體之資產，在系統遭受損毀或失效時，會使得國家安全、經濟安全或其他安全保護受到重大衝擊，如交通系統、水資源系統及電力系統等。關鍵基礎設施之間的相互聯繫和相互依存的關係是複雜的，一個關鍵基礎設施中某元件的破壞，可能會導致另一關鍵基礎設施嚴重損壞，造成重大損失。故完整的關鍵基礎設施相依性資料對於建立災害管理或國家安全來說非常重要，要改善目前的救災成效，如何取得正確關鍵基礎設施相依性資料是重要議題。 電力系統包含發電、輸電、變電、配電及提供穩定能源到各個設施系統，而災害發生後，是否恢復供電也是救災的重要指標。本論文以電力系統為主要研究對象，將原本使用不同資訊建立之設施運轉模型同質化後之結果分析與比較，將電力系統在電力傳輸過程中各電力系統元件之輸配電情況，轉換為關鍵基礎設施服務水準在設施服務傳輸轉換間各設施元件之服務關係，可用以分析關鍵基礎設施間之相依性，做為緊急修復順序之參考，以降低災害損失。 Critical infrastructure systems include electric power, water distribution, transportation and telecommunication facilities and are important elements in maintaining human economic activities and country development. In critical infrastructure systems, electricity transmission systems are the most important element among all the others. In recent years, the electricity transmission systems have been stressed by increasing natural hazards and human errors, leading to malfunction. The electricity transmission systems are the main study target of this research. The simulation of the dependences between infrastructures by the electricity transmission systems can be applied to estimation of the critical infrastructure systems. Disaster mitigation officials can employ the proposed approach to explore critical infrastructure interdependency (CII) and to design countermeasures when a disaster hits certain areas.
