AHP-Entropy Weight Based Railway Passenger Station Operation Safety Assessment Model

Based on the AHP-entropy weight model, this paper proposes a safety assessment and optimisation method for railway passenger station operation. Firstly, the hierarchical analysis method (AHP) is used to construct the evaluation index system, and the initial weights are calculated by combining the expert scoring method. However, the subjectivity of the AHP method may lead to weight allocation bias, so the entropy weight method (EWM) is introduced to correct the weights and make the weight calculation more objective. Through the combined AHP-entropy weight model, the rationality of expert experience is retained, and objective data are used to optimise the weight allocation, which improves the scientificity of the evaluation. Based on the weights of the indicators, the key factors affecting the safety of railway passenger stations are identified, and targeted optimisation measures are formulated.
