摘　　要：针对工程试验过程中需要对多套测量设备的跟踪质量进行评定,以便快速、准确地选择测量数据的实际需求,对层次分析法原理及应用步骤和对数最小二乘法原理进行了简要介绍,通过实际算例对方案层、准则层和目标层进行选取,建立了测站设备跟踪质量评定的层次分析模型;综合层次分析法、隶属度和对数最小二乘方法对设备跟踪质量进行综合评定,结果表明与专家评定的结论一致。该方法将定性分析与定量分析相结合,减少了单纯的人为定性评定的随机不确定性,为测量设备跟踪质量评定提供了一种选择。In engineering test process,we need evaluate the tracking quality of multiple sets of measurement equipment,so as to perform fast and accurate selection of measurement data.Firstly,the principle of AHP and application steps and logarithmic least squares principle are introduced.Through a practical example,the case layer,criterion layer,and target layer are chosen respectively.And the analysis model of station equipment tracking quality assessment level is established.Next,such methods like AHP,membership,and least squares are integrated to evaluate the quality of tracking equipment.And the results are consistent with the conclusion of expert evaluation.The method combines qualitative analysis with quantitative analysis,reduces the uncertainty of the qualitative assessment of human,and provides a choice for the quality evaluation.
