Application of Improved Fuzzy Grey Relation Model in the Evaluation of Crane Accidents Emergency Plan

The emergency management of crane has received widespread attention from the industry. Most accidents are sudden events that will cause huge loss of life and property. Based on the emergency rescue process, this paper constructs a performance evaluation index system for emergency plans for crane from three aspects: emergency preparation, emergency operation and post-processing, and uses the improved fuzzy grey correlation model to evaluate the emergency plan of crane. First, use fuzzy theory to quantify the indicators. Then, use the entropy weight method to objectively weight the indicators, and use gray correlation to determine the priority of the scheme. Finally, the effectiveness of the model and method was demonstrated using the emergency plan assessment of the crane.
