The Application Of Entropy Weight Multi-Objective Decision In The Scheme Optimum Seeking Of Real Estate Investment

Real estate is one of the economic development foundation industries of all the countries around the world. The real estate trade in China is still in its initial stage, and the research on investment decision is not perfect yet. It is an important research focus on how to select the best one among the schemes, and how to select the proper decision methods to measure the factors and targets, and how to evaluate the schemes properly without subjective attitudes.The thesis starts with the general situation of the investment of real estate, following with the analysis of the current status and issues of the real estate trade in China. Considering the theories of the real estate investment decision methods both domestic and abroad, the entropy weight multi-objective decision method is selected in seeking the optimum scheme. Secondly, after analyzing the characters and influencing factors of investment of real estate projects, the thesis introduces three investment evaluation indexes in details. Considering the influencing factors of investment, a comprehensive evaluation index system is used according to a real case. Thirdly, based on the comprehensive evaluation index system, the entropy weight coefficient evaluation model is introduced. Finally the practicality is validated with a case.A more reasonable calculating method is attempted in this thesis during the making of the determination of comprehensive weight of assessing indexes, by taking into consideration that the comprehensive weight is equilibrium between subjective weights and objective weights. This combines the subjective and objective consideration of the entropy weight by data comparing; In the situation that final values equal to or are close to each other, considering the equilibrium of schemes variables, the model is modified with the equilibrium coefficient. Lastly the effect and practicality is validated with a case.Through the study and analysis of the thesis, the entropy weight multi-objective decision in the scheme optimum seeking of investment decision of real estate is reliable. The entropy weight coefficient evaluation model can abate the subjective influence in project evaluation and selection, and enhance the credibility and reliability of the evaluation.
