Price parameter generation method and device of power grid project equipment material

Abstract

The invention provides a price parameter generation method and device of a power grid project equipment material. The price parameter generation method comprises the following steps: selecting a plurality of primary selection models from a preset model library based on a time dimension and a price volatility; selecting at least one final selection model from the plurality of primary selection models according to a plurality of preset indexes; and judging whether the number of the at least one final selection model is greater than 1, and if so, performing equal weight combination calculation by using the at least one final selection model to obtain comprehensive price parameters of the power grid project equipment material. According to the price parameter generation method and device of the power grid project equipment material provided by the invention, as a plurality of influence factors and a plurality of indexes of the price of the power grid project equipment material are comprehensively considered, compared with the traditional simple price statistical approach, the generated comprehensive price parameters are more accurate, and the price prediction risks of enterprises are reduced.

Description

technical field [0001] The invention relates to the field of power grid engineering management, in particular to a method and device for generating price parameters of power grid engineering equipment materials. Background technique [0002] In the construction of power grid projects, the purchase cost of equipment and materials accounts for more than half of the total price of power grid projects. The prices of equipment and materials fluctuate frequently with the market, making price control more difficult. Enterprises often need to regularly issue information prices based on the past bidding situation of equipment and material prices. The unreasonable determination of information prices is an important reason for the high project balance rate. At the same time, the market price of equipment and materials is affected by many factors including the law of supply and demand, inflation, technological progress, macro-control policies and regional development, and changes rapidl...

AI Technical Summary

Problems solved by technology

[0003] At present, the research on the purchase price of power grid engineering equipment and materials is seriously insufficient. The existing research mainly stays at the stage of price statistics in the early stage and the analysis of factors affecting the price of equipment and materials. The price statistics method is too simple, and the influencing factors are relatively general. The research on controlling the cost of equipment and materials such as price forecasting and price control is even more insufficient
