Classification, Prioritization, Intrinsic Value, Critical Infrastructure, Assets, Indices, Best-Worst.

Today, the growth and development of societies in economic, social, political, public health and security dimensions depends on the performance of critical infrastructure. Infrastructure management and management is one of the most important concerns in this field to ensure their proper performance and sustainability against the risks ahead. Securing and safeguarding critical infrastructure and key assets against all risks, factors and adverse conditions is one of the most challenging issues for governments due to limited financial resources. One way to overcome these limitations is to prioritize and classify infrastructure. Proper determination of priorities, using measurable indicators, in addition to distinguishing critical assets and infrastructure from non-critical ones, leads to optimal resource management and increases the effectiveness of measures to protect critical infrastructure. The main purpose of this study is to evaluate and validate the indicators of the vitality of critical infrastructure and determine the weight of each indicator by the best-worst method. The results of studies performed on 26 initial indicators and the validity and reliability of the indicators led to the final confirmation of 24 indicators. Weighting of indicators was done according to the best-worst method (BWM). Based on calculations based on the opinions of selected experts, the index "Number of population at risk" with a weight of 8.5%, "Independence and territorial integrity" with a weight of 7.8% and "Defense capability" with a weight of 7.8%, respectively, have the highest weight and importance. Are assigned among the indicators.
