Introduction: Today, accident investigation and analysis is an important component of safety programs in preventive measures. Incident investigation involves collecting all the information and actual interpretations of an incident, analyzing information to find out the causes of the incident, and writing an incident report.
Methods: This descriptive-analytical article was conducted to determine the most important criteria for investigating and selecting the techniques of accident investigation as well as analyzing and selecting the best method of accident analysis in the events of the power plant industry. In this research, previous research studies were studied and expert opinions were collected with regard to the most important criteria for choosing a specific accident analysis method. Later,  the 4 accident analysis methods was applied in a special power plant accident and the decision matrix was designed based on the strengths and weaknesses of the model formation. Finally, these four methods were prioritized using the Topsis decision-making method.
The key factors in investigating the main criteria for selecting an incident analysis method  included the ability to understand the sequence of events in the model, identifying the root causes, descriptiveness and ability to provide reasons for managers and specialists, the need for technical experts, and the time criterion. The TRIPOD BETA method was selected as the best method for analyzing the power accidents.
Conclusion: The TRIPOD BETA method was introduced as the most effective method for investigating power plant accidents.
