Of the research on deforming monitor, the design of deforming networks and its optimization is one of the basic problems. In this paper, from the general optimizing theory of the design of geodetic networks, some problems relating to the optimizing design of deforming networks have been discussed. These problems include as follows: 1) recommending to add the optimizing design for repretitional period of observation of deforming networks as fourth order design, based on a synthesis of classification on design of geodetic networks; 2) studying the problem of fourth order design and its solution, through analysing the objective functions on various order designs of geodetic networks; 3) giving the calculating formulas of the strain and rotation tensols from deforming quantities and discussing the criterion matrices for deforming networks; and 4) summing up the characters and principles on design of deforming networks and setting forward a flow chart for practising the optimizing design of deforming networks. In order to establish the scheme of the optimizing design on deforming networks and to practically carry out it, the basis has been further been given by means of this research.
