【摘要】：评估铁路应急预案是铁路应急管理中的关键环节,针对现有预案评估方法的不足,提出基于信息公理和多粒度语言值的铁路应急预案评估方法。考虑专家评估中的偏好,采用多粒度语言评价值,并采用区间二元语义方法对多粒度语言值进行处理,避免信息转换过程中的缺失;利用群体评价值与其数学期望值之间的偏差,提出求解基于区间二元语义的指标客观权重,并求解综合权重;提出基于区间二元语义的信息量计算方法,根据信息公理的信息量最小方案最优原则,评估出最佳应急预案;将该方法与多准则妥协解排序法(VIKOR)和逼近理想解方法(TOPSIS)比较分析,验证了该方法的可行性和有效性。
[Abstract]:The evaluation of railway emergency plan is a key link in railway emergency management. In view of the shortcomings of the existing evaluation methods, a railway emergency plan evaluation method based on information axiom and multi-granularity language value is proposed. Multi-granularity language evaluation value is adopted and interval binary semantic method is used to deal with multi-granularity language value to avoid the missing in the process of information conversion, and the deviation between group evaluation value and its mathematical expectation value is used. The objective weight of the index based on interval binary semantics is solved and the comprehensive weight is solved, and the method of calculating the amount of information based on interval binary semantics is put forward, and the optimal emergency plan is evaluated according to the principle of the minimum scheme of information quantity of information axiom. The feasibility and effectiveness of the proposed method are verified by comparing the method with VIKORand the approximate ideal solution method (Topos).
