Problems solved by technology

[0003] The existing cost evaluation methods for power transmission and transformation projects are basically based on theory. The data on which this method is based cannot fully fit the reality, and the evaluation parameters for the cost evaluation of power transmission and transformation projects are relatively limited. Therefore, there are still many disadvantages in the existing cost evaluation methods of power transmission and transformation projects. On the one hand, the reference data of the existing cost evaluation methods of power transmission and transformation projects are not real-time. The cost evaluation method of power transmission and transformation projects cannot effectively improve the reference of the cost evaluation results of power transmission and transformation projects. On the other hand, the existing cost evaluation methods of power transmission and transformation projects cannot effectively improve the cost of power transmission and transformation projects. Accuracy and reliability of assessment results

Abstract

The invention discloses a power transmission and transformation project cost evaluation method based on data feature mining and analysis. The power transmission and transformation project cost evaluation method based on data feature mining and analysis comprises the following steps: obtaining the number of historical projects corresponding to recent five years, calling project information corresponding to each historical project, analyzing the project information corresponding to each historical project, and counting cost influence coefficients corresponding to each parameter of each historical project information; collecting project information corresponding to a project to be manufactured, matching and screening the project information corresponding to the project to be manufactured and the project information corresponding to each historical project, and counting a final estimated manufacturing cost corresponding to the project to be manufactured according to a cost influence coefficient corresponding to the screened historical project with the highest matching degree. According to the method, the reference and the accuracy of the power transmission and transformation project cost evaluation result are greatly improved, and the scientific evaluation of the power transmission and transformation project cost is realized.

Description

technical field [0001] The invention belongs to the technical field of engineering cost and relates to a cost evaluation method for power transmission and transformation projects based on data feature mining and analysis. Background technique [0002] With the continuous development of the social economy and the increasing demand for electricity, power transmission and transformation projects have gradually become popular investment projects. Project information is becoming more and more convenient, and it also provides investors with a more scientific basis for the selection of power transmission and transformation projects. In order to maintain the stability of the investment market and control the cost of various power transmission and transformation projects, Therefore, it is very important to evaluate the cost of power transmission and transformation projects. [0003] The existing cost evaluation methods for power transmission and transformation projects are basically...
