Measuring the Impact of Urban Infrastructure on each other in terms of Passive Defense Perspective using Fuzzy DEMATEL, Case Study: Guilan Province

Research objectives: In construction of main urban infrastructures, observing the principles of passive defense in order to maintain safety and reduce vulnerabilities in critical situations is very important. In this study, critical infrastructures were identified and ranked. Finally, the most effective and impressible infrastructures for successful management in non-operating defense were identified. Method: In this study, urban infrastructures evaluated and ranked in relation to each other. Initially, 32 urban infrastructures were identified and introduced in the case study of Guilan province. Then, using the Friedman method, unimportant infrastructure was removed.Finally, most effective and impressible infrastructures of the remaining 23 infrastructures were measured by fuzzy DEMTEL technique. Finding: The infrastructure of the power plant has the least influense on other infrastructures, and the infrastructure of transmission lines and pressure boosting stations has the least influense. Also, airports within urban areas recive the most impact and air and ground cabling infrastructure recive the least impact from others. Conclusion: Power plant infrastructure is the most effective infrastructure that needs to be rebuilt or re-engineered according to the principles of passive defense due to the time it takes to repair and the high cost of repairing it in times of crisis as well as it is need for other infrastructures.
