Analysis on operation risk factors of urban rail transit based on fuzzy analytical hierarchy process

From the perspective of systems engineering, based on comprehensively analyzing the operation risk factors in urban rail transit, an evaluation model of operation risk factors about the urban rail transit was built by combination of the fuzzy analytical hierarchy process. The fuzzy consistent judgment matrix evaluating the operation risk factors was established and the important weight of each risk factor was calculated, finally order of each kind of risk factors was obtained. Direct at the order results, some reasonable control measures are proposed, therefore the science basis is provided for lessening accident occurrence and improving urban rail transit safety situation.
