事件的指标函数

To solve the problem that there is no early-warning technique for conflict management of irregular flight services,the matter element analysis in extension theory was used to build an early-warning model with 5 indices(anticipated delay time,margin of resources,affected passenger number,service ability and event status),each of which has 5 grades(normal,attensional,precautious,danger and crisis).

为解决不正常航班服务管理中无冲突预警的问题，用物元分析方法，建立了以预计延迟时间、运力资源富余度、滞留人数、现场服务能力和意外事件情况为特征指标，以安全、注意、警戒、危险和危机为分类等级的预警模型。鉴于冲突中各种因素相互影响，采用简单可拓关联函数确定模型中的评价权重，并以定量结果确定预警等级。实例验证表明，该模型可用于对服务环境状况的定性评价，或提供定量的预警信息

Secondly, it aimed the research on model and method of railway large-sized passenger terminals emergency capability assessment. It designed the emergency capability assessment index system including the MECE principle during the design. After in-deep studied the hierarchy entropy analysis method to dealing with the weight, it calculated the weights of the emergency capability assessment indexes. And it studied the risk assessment model based on the set-valued statistics and fuzzy comprehensive evaluation model, proposed the emergency capability assessment model based on the risk. During the research on the fuzzy comprehensive evaluation model, the paper improved the circular distribution subordinate function to calculate the index membership.

其次，对铁路大型客运枢纽站突发事件应急能力评价的模型和方法进行了研究，建立了应急能力评价指标体系，提出了MECE评价指标设计原则；深入研究了确定指标权重的层次熵分析法，并计算出了铁路大型客运枢纽站突发事件应急能力评价指标权重；构建了集集值统计风险评价模型和模糊综合评价模型于一体的风险应急能力评价模型，并在模糊综合评价研究中，改进了确定单指标隶属度的圆形分布隶属函数法。
