Background: Process industries are very complex and defective, therefore they are prone to crisis. An industrial crisis is an event with a low likelihood of occurrence but severe consequences that threatens the survival of an organization .It is described by the cause or the reasons of ambiguous and unknown solutions. It is also believed that the decisions should be made as soon as possible and not under pressure from time to time. This study was aimed to analyze and to value factors affecting industrial crisis management in the process industries through fuzzy AHP. Methods: This study was conducted in Tehran in 1397. Following a library study and the use of experts, a comprehensive and suitable model for managing the industrial crises was selected. A paired comparison questionnaire was developed to allow the experts to compare the elements two by two and to express the relative superiority of one to the other. Finally, by using the fuzzy hierarchy analysis method, the importance of this criteria and sub-criteriafor crisis management was identified. Results: The results, compared with other factors in the research, showed that the crisis prevention factor had the highest relative weight (6 3/0). After this factors, disaster preparedness (22/0), crisis management (1 2/0), and post-crisis management (03/0) had the highest importance. “Risk management”, "training, simulation", "identity crisis" and "assessing, correcting" were respectively the most important sub-criteria for each phases of crisis management. Conclusion: The present study showed that crisis prevention was the most important criterion for the effective management of industrial crises and" rapid alert inspection", "risk management" and "response to emergency conditions  " were considered to be the sub-criteria. So, in order to effectively manage the industrial crisis, the managers and investors need to pay most attention to the risk management sub-criteria (the most important sub-criteria was to prevent a crisis with relative weights 4- 4/0 compared with other sub-criteria of this factor).
