Abstract: To improve the accuracy of the evaluation for urban building fire accident emergency response capability, a set of emergency capability evaluation index system was constructed. Combined with the analytic hierarchy process to formulate a percentile deductible quantitative evaluation standard, the principal component analysis was used for dimensionality reduction processing; the model was established based on multiple linear regression and support vector machine. The results indicated that the evaluation index system of high-rise building fire emergency response capability can effectively realize the quantitative processing of indicators. The prediction scores of the two models have an insignificant gap, and both of them are suitable for the evaluation of urban high-rise building fire emergency capability.
