Abstract: In order to grasp the security condition of railway luggage and parcel transportation, the influencing factors of railway luggage and parcel transportation safety were analyzed based on its characteristics of small transport volume, variety of types, and many operational links, and an evaluation system of railway luggage and parcel transportation was established. Using variable fuzzy set theory, based on the relative membership degree and relative difference function, the important consistency sorting theorem was applied to determine the weights, and the evaluation results were quantified by the level eigenvalues to improve the reliability of the evaluation results. Taking the safety evaluation of a railway station luggage and parcel as an example, the operability of the method was verified. The results show that this method has reliability and operability and can be used to evaluate the safety of railway luggage and parcel transportation.

Key words: railway luggage and parcel transportation, variable fuzzy sets, safety evaluation, level eigenvalues, important consistency sort
