微震监测传感器布设方案评价模型及应用

为了弥补微震监测传感器布设方案仅依靠经验进行比选的不足,基于逼近理想解的排序法(TOPSIS)的基本思想建立了传感器布设方案评价模型.首先,从技术条件、经济条件、工程条件三方面选取对传感器布设方案影响最大的指标构建评价指标体系.其次,考虑指标处于边缘状态时对权重的影响采用变权计算得到各方案的指标权重.最后,利用逼近理想解的排序法计算各方案综合优劣度.用该评价方法评估用沙坝矿微震监测传感器布设方案,得出各方案优劣程度,为微震监测传感器布设多方案比选提供了一个较好的途径.

Evaluation Model of Microseismic Monitoring Sensor Layout Scheme and Its Application

A sensor layout evaluation model based on the technique for order preference by similarity to ideal solution (TOPSIS) was established to make up the layout deficiencies of empirical design. First， the indices which had great impacts on the choice of sensor-layout programs were selected according to the technical conditions， economic conditions and engineering conditions to build evaluation index system. Second， considering the influence of the indices at the edge state on the weight， the variable weight calculation method was used to get the index weights of all schemes. Finally， comprehensive advantages and disadvantages of each scheme were calculated by TOPSIS. This method was used to evaluate microseismic monitoring sensor layout programs to obtain the good and bad of each program. This model provides a good way for the layout of microseismic monitoring sensors.
