基于熵值与变异系数定权法的控制网平差作者：周斌来源：《科技创新与应用》2019kis2009
年第21丛连彪期 摘 要：熵值与变异系数定权都是一种客观的定权方法，能克服常规经验定权的不足。文章将这两种客观定权方法引入工程控制网平差中，并与常规定权方法进行比较。通过算例验证表明，文章方法显然比常规定权法的精度要高。 关键词：熵；变异系数；边角网；权

Abstract： Both the entropy value and the coefficient of variation are an objective method of determining power， which can overcome the deficiency of determining weight by experience. In this paper， these two objective weight methods are introduced into the side and angle adjustment of networks and compared with the regular weight method. From the application examples， the results showed that the adjustment accuracy of our proposed method was obviously higher than that of the regular weight method.
