Comprehensive assessment of aircraft cabin fire hazard based on entropy weight-cloud method

In this paper, the index system of aircraft cabin fire risk assessment is established by considering the various influences in the operation process. Then the cloud image is output by analyzing each index in the system. Finally, the risk status of aircraft cabin is discussed. The conclusion shows that the cabin fire risk level of the selected Boeing 737-800 is normal. Although the number of subjective risk indicators accounts for only 11%, the expected value is 158% of the objective risk indicators. The research method in this paper can be used to evaluate the cabin fire of any aircraft and provide theoretical support for its safety management.
