Abstract: In order to improve security service quality of railway passenger stations and strengthen safety management, QFD was used to evaluate service quality according to required quality standard of stations. Firstly, relationship matrix was established between security service indicators by expert. Secondly, safety indicators at the same level were screened out based on maximum relation degree principle and safety technical indicators that are most related to the quality of the safety function were found out to form a judgment matrix and to calculate their importance. Then passengers' satisfaction was obtained from it and ]safety service quality was evaluated. Finally effectiveness and practicability of the model was verified with a railway passenger station as an example. The results show that QFD is reliable in evaluating the quality of railway passenger security services. It can find out main factors that affect service quality and thus help improve in this part.
