摘要
物流经济时代,高速铁路网络的日益丰满,为高铁快运的发展创造了有利条件。铁路企业利用高铁列车确认车、空闲车厢、大件行李存放处等位置开展高铁快运,充分发挥高铁运输的优势,但在提高经济和社会效益的同时,对高铁运营安全也提出了挑战。考虑到影响高铁快运安全的因素众多且具有模糊性的特点,提出将模糊综合评价和模糊模式识别相结合的评价方法,建立高铁快运安全评价指标体系,采用层次分析法(AHP)确定指标权重,基于实地调研由专家打分来量化指标特征值,对高铁快运进行安全评价。结果表明:该方法具有科学性和实用性。
In the era of logistics economy,the high-speed railway network is becoming increasingly full,andcreating advantages for the development of high-speed railway express.Track status confirmation trains,idle carriages and large luggage storage places were used by railway enterprises to send parcels,which gives full play to the advantages of high-speed railway transportation,however,while economy and social benefits being improved,there are also many challenges to the safety of high-speed railway operation.In this paper,considering that high-speed railway express safety was affected by many fuzzy factors,an evaluation method which combined fuzzy comprehensive evaluation and fuzzy pattern recognition was proposed,thus an safety evaluation index system of high speed railway was established. The AHP was applied to determine the weights,and the index characteristic values were quantified by the expert rating based on the field research,therefore,finally,the safety evaluation of high-speed railway express was carried out. The results show that the method is scientific and practical.
