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 problem of the accuracy of the diagnosis in the subway warning system and to determine whether the police intelligence is controllable and controllable, a matter-element model is established based on the extension theory and the correlation function in the extension set theory is used to quantitatively study the controllability. Under the premise of fully recognizing the warning sign and the monitoring index, taking the ground wall seepage as an example, the index matter element model is established and the Monte Carlo simulation method is used to simulate the status quo matter-element model. The warning and controllable levels are divided , Respectively, and no alarm and lower alarm for the control purposes, using the correlation function as a calculation tool to quantify the diagnostic controllable. The results show that it is more difficult to control to the no-alarm state and the controllability is lower. However, for the purpose of lowering the warning level, the controllability is higher.
