Research and Implementation of Index Weight Calculation Model for Power Grid Investment Returns

摘要

Investment evaluation of electric power grid is an evaluation of proportional relation between the profit, which is gained from investment money of electric power grid enterprise in a certain period, and the investment which the profit occupy or consume. The investment evaluation of electric power grid is reflected by the index evaluation system, the importance of which is reflected by index weights, the precise calculation of the weights have a very important role. In this article, we have established a weight calculation model, the coefficient of variation method, Delphi method, entropy method are used to calculate the weight, and finally combination of three methods to calculate the weight, get the Combination weights.
