| description | The invention relates to a power transmission and transformation project cost dynamic control target calculating system and a calculating method. The method comprises the steps that a power transmission and transformation project cost data set is established; data preprocessing is carried out, and a project feature vector set is defined; similar project identification is carried out by inputting a similar project identification condition; a fuzzy identification technology is used to select similar projects; before a power transmission and transformation project cost dynamic control target is calculated, similar projects are selected in historical data samples according to the attribute of a cost control object; a weighted Hamming distance proximity formula is used to calculate the proximity of a target project of cost control and historical data; according to the number of the samples and the sample proximity, a proximity threshold is determined; according to the proximity threshold, whether the number of sim |
