基于可变模糊集理论的铁路行包运输安全评价
|
摘要
为掌握铁路行包运输安全状况,根据其运输批量小、种类繁杂、作业环节多等特点,分析铁路行包运输安全影响因素,建立铁路行包运输安全评价指标体系。运用可变模糊集理论,以相对隶属度和相对差异函数为基础,应用重要一致性排序定理确定指标权重,并通过级别特征值量化评价结果,以提高评价结果的可靠性。以某铁路车站行包运输安全评价为实例,验证该方法的可操作性。结果表明:该方法具有可靠性和可操作性,能够用来评价铁路行包运输安全状况。
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.
