基于层析分析法的水准测量误差分析

The Analysis of Leveling Errors Based on AHP

按照层次分析的步骤,首先对测量工作中影响水准测量误差的有关因素进行采集和分析,确定影响其测量精度的因素。在定性分析的基础上,从定量的角度找出影响水准测量误差的主要制约因素。由层次分析法权重计算的基本方法,计算权重向量和进行一致性检验。最后进行权重总排序,并对权重值做出合理分析。针对误差因素权重的大小,在减小误差措施方面提出有利于提高水准测量精度的办法,希望可以为施测的工程技术人员提供参考。

According to the step of AHP（Analytic Hierarchy Process）,firstly,some related factors that affects leveling errors were gathered and analyzed.Then,based on qualitative analysis and basic method of AHP weight calculation,these main factors in terms of quantitative analysis are found out and the weight vectors and inspect consistence of vectors are calculated.At last,weight values are sorted out and reasonably analyzed,and in light of weight values,methods are put forward in favor of improving leveling accuracy in terms of decreasing errors.It is hoped that this paper can be reference to technician in engineering construction.
