Evaluation of the vulnerability of water supply facilities with the AHP and RAMCAP combined methods

The supply and distribution network for drinking water is one of the key assets and infrastructure of any country and is vulnerable to terrorist attacks. Access to safe drinking water is one of the vital needs of communities.Importance of water supply facilities, sometimes in the enemy's sabotage operation, these facilities are targeted as strategic centers, which may lead to serious damage to society and sometimes security crises. Regarding this issue, in this research, a total of vulnerabilities was investigated by providing a combination of analysis and risk management for vital asset protection (RAMCAP) and Analytical Hierarchy Process (AHP) analysis of the total water infrastructure of Tehran. The present research is an applied research (extension type). In this way, a questionnaire (quantitative) method has been used for collecting and analyzing information and the research method is descriptive-analytic. The results show that the main facilities identified in the city of Tehran's water supply system, according to the criteria for the ability to discover and identify, the ability to reach the target, the weakness index, the index of resilience, the secondary damage index, the combined effects index, the most vulnerability of the Letyan dam is 0.0858, and Amir Kabir Dam with a vulnerability of 0.0779 and Taleghan dam with a vulnerability of 0.0721 are included in the next assessment. The lowest vulnerability was 0.0133 and 0.0063, respectively, based on the defined criteria for storage tanks and distribution network with vulnerability numbers.
