A Comprehensive Risk Management Framework for Transport of Hazardous Materials in the crisis

Acceleration of industrial development, especially in developing countries, has led to an increase in the transportation of hazardous materials and, consequently, an increase in hazards and accidents, which are sometimes combined with critical conditions that complicate the situation and The risk management process becomes more difficult. The purpose of this paper is to provide a model that is easy to use and comprehensive enough to identify and accurately assess the components of risk management in complex critical situations. This model consisted of four steps of identification, analysis, evaluation and control and used tools such as system dynamics and fuzzy AHP and was implemented in a hydrazine transport sample in war conditions. In the identification stage, 8 criteria and 46 sub-criteria were identified. In the risk assessment phase, the limitations of dealing with crisis situations were considered in determining acceptable limits. In the risk analysis stage, while introducing decision factors in crisis situations, criteria and sub-criteria were weighted with fuzzy AHP, it was found that population density and defense facilities are the most important in the risk of transporting hazardous materials, followed by driver-related sub-criteria. Finally, while presenting risk control planning, ways to reduce risk to an acceptable level were examined. At this stage, the effectiveness of each sub-criterion of total risk was calculated and taken into account
