摘要
为解决地铁预警体系中诊断的精确度问题,确定警情是否可控及可控程度,基于可拓理论建立物元模型,利用可拓集合理论中的关联函数来定量化研究可控度。在充分识别警兆及监测指标的前提下,以地墙渗漏为例建立指标物元模型,运用蒙特卡洛模拟方法模拟警情现状物元模型;对警度及可控度的级别进行划分,并分别以无警和降低警度为控制目的,以关联函数为计算工具定量化诊断可控度。结果表明,要控制到无警状态较难,且可控度偏低;但以降低警度为目的,则可控度较高。
In order to solve the precision problem diagnosis in subway forewarning system,identify whether alarm is controllable and controllable degree,extension theory was established based on matter-element model and proposes the method of making use of the correlation function in extension set theory to quantify the degree of controllability.Under the premise of fully identifying warning and monitoring indexes,take the leakage of diaphragm wall as example to build the index of matter-element model,simulate the alarm status matter element model by using the Monte Carlo method.It grades the degree of warning and controllability.Besides,by taking zero warning and warning reduction as control purpose,correlation function as calculating device,The diagnostic results show that it’s more difficult to control to no alarm state;but high degree of controllability in order to warning reduction.
