Study on the Investment Decision Making for Power Project Based on Multi-objective Grey Correlation

Project investment decision making system is a typical grey system which is characterized by some information uncertainties.This paper combines the grey system theory with AHP to establish a model and calculate the judgment matrix through weighted grey correlation,which can provide an efficient decision making method for decision makers.The grey correlation analysis method is used in the process of power project investment decision making,in which the various factors are weighted through AHP method by taking into consideration of their importance and the optimal investment scheme is selected from the alternative schemes according to their weighted grey correlation values.This method makes the decision making process for power project investment more scientific.
