区域重力网改造的优化设计

ON OPTIMUM DESIGN OF REFORMING LOCAL GRAVIMETRIC NETWORK

本文首先论证了区域重力网改造的必要性,进而讨论了综合评价重力网质量的定量标准,并以此作为区域重力网改造优化设计的目标函数,进而用多目标规划的评分方法求本问题的最优解。文中给出有关数学模型和算法。最后总结了区域重力网改造应注意的几个问题。本文提出的理论和方法亦可推广应用于一般测量工程的精度分析和优化设计中。

The authors discuss in this paper first the necessity of reforming the local gravimetric network. For judging the quality of a gravimetric network, a general standard is set, which is then taken as the aimming function for the optimum design of reforming work. The solution of that is based on a judging mark method of multi-objective programming, its mathematical model and arithmetic are also given. For conclution, some principles of reforming work are suggested. The method of multi-objective programming used in this paper can be applied to other sort of optimum design for practical survey engineering and their accuracy analysis.
