边角网二类优化设计

本文首先根据控制网的可靠性理论,讨论了它的设计方法;其次,在综合考虑精度、可靠性和费用准则的基础上,应用线性规划法,推导出边角网二类优化设计的通用模型;最后,通过测边网、方向网和边角同测网二类优化设计的例子,详细说明了边角网二类优化设计的一般方法。

Second-Order Design of Linear-Angular Geodetic Network

According to the reliability theory of control networks,this paper discusses the reliability design of net-works. On the basis of the consideration of precision,reliability and cost,the general mathematical model ofSecond-Order Design for linear-angular networks is given here by linear programming method. Finally,bythree design examples,the general method of Second-Order Design is illustrated in detail for the distance net-work,direction network and combined linear-angular network.
