Embodiment Construction

[0025] The principle of the rapid estimation method in the present invention is: the principle of the whole process, the principle of data mining technology, the principle of hierarchical analysis, the principle of fuzzy similarity priority ratio, and artificial neural network.

[0026] The fast estimation method content of the present invention comprises:

[0027] (1) For the huge cost data of power grid construction projects, establish a database to realize historical data query

[0028] Collect historical data of power engineering costs of different project types, and collect historical engineering cost data according to project type, voltage level, construction nature and other attributes. The database mainly includes the estimation, budgetary estimates, bidding, Technical and economic data of settlement and final accounts results. Form a historical project cost database with wide data coverage and relatively complete data content, provide a relatively complete collection...

Abstract

The invention provides a power grid construction new project cost rapid estimation method based on fuzzy mathematics. The method comprises a step of establishing a database to realize the query of historical data for the huge cost data of a power grid project construction object, a step of carrying out accurate investment calculation on a power grid project with an investment need based on historical cost data mining and general cost application, a step of analyzing and monitoring a price fluctuation main reason by using a mathematical modeling method, and establishing a prediction model, and a step of establishing a cost early warning mechanism in an investment decision-making stage with the combination of the cost control line. Through the implementation of the method, the rapid query of historical project investment can be realized, the accurate investment calculation of the power grid project with an investment need is carried out, the working is effectively and accurately developed, and the scientific decision-making of investment is supported.

Description

technical field [0001] The invention relates to a method for rapidly estimating the cost of a new power grid construction project based on fuzzy mathematics, which belongs to the technical field of electric power. Background technique [0002] Fast and accurate project cost estimation is based on scientific technical analysis. At this stage, the huge cost data involved in the whole process cost management of the project, such as power engineering estimation, budget estimation, bidding, settlement, final account, etc., has not yet obtained deeper data mining, analysis and application, and has not yet formed a standard and intelligent analysis method In order to realize the rapid transformation from basic data collection to result output and result application, to a certain extent, it restricts the level of technical and economic work of power grid engineering, and hinders the process of rapid development of technical and economic management, analysis and research to lean and ...
