| 摘 要： | 讨论矿区（城市）测量控制网改造的优化设计问题．优化设计分４个阶段：零阶段设计讨论控制网的基准选择问题；第１阶段设计解决点位优化问题；第２阶段设计解决费用最优问题，即观测权的最优分配问题；第３阶段设计计算最少加测角度，使之达到精度要求．整个设计采用坐标未知数的协因数阵的迹最小时为最优．

| Abstract: | The optimization design for remaking the survey control network of mineral deposit was discussed in this paper. The optimization design was divided into four stages. In zero stage,the base selection of the control network was discussed. What was designed in the first stage was the optimization of point location. The aim of the second stage design was to solve the optimization of the expense, i. e., the optimal distribution of the observation weight. Thecalculation of the least numbers of the angles to be measured additionally was considered during the third stage design in order to meet the accuracy requirement. The optimization design corresponded to the minimal trace of the cofactor matrix for the coordinate unknown number. |
