| Abstract: | The related formulae, namely the definition of the sensitivity of the precision and the reliability, for the changes of the precisions of the observed values and the unknown parameters and the reliability of a network, and the means of designing scheme for network optimisations based on the sensitivity are deduced. The importance to that utilized in the optimum design for network are also testfied by the practice of contrasting in various plans with the data from a mine triangulation network. |
