整数规划在施工控制网观测精度优化设计中的应用

使用数学解法来获得最优的控制网观测量的权，必须转换成观测方案后才能实现。怎样才能使转换后的观测方案既避免主观因素的影响，又具有最优的设计功能，是本文所力图解决的问题。文章顾及施工控制网原始数据误差的影响，提出利用整数规划进行观测精度优化设计的数学模型和计算方法，使优化设计理论更趋完美。文章最后通过算例说明该法在控制网观测精度优化设计中的作用。

INTEGER PROGRAMMING USED IN OPTIMAL ACCURACYDESIGN OF CONSTRUCTION CONTROL NETWORK

: Application of the integer programming in the optimal design of observation accu racies in construction control networks. In practices the weights of observations in a network obtained from the second order design solution must be changed to the numbers of repeat measurements. To be less influenced by subjective factors, a method using the integer programming is proposed. In this paper the effects of initial data errors of higher order control points on the desired quemtities are taken into consideration and the computation method is developed. An example is provided to illustrate the proposed method.
