Apply Entropy Coefficient Optimized Model To Investment Decision-making Of Composite Real Estate

Starting with the analysis of the concept of investment decision-making of composite real estate project, this paper states the essential factors, significance, system, procedure of investment decision-making of composite real estate project, and advances the economic evaluation index of composite real estate project based on detailed research into market constitution, index, current situation of real estate. Meanwhile this paper studies the main influential factors of economic index of composite real estate project according to the analysis of the real estate market. Then, on the basis of the foundational analysis of entropy and entropy coefficient, the optimized entropy coefficient model is built. Thereafter the model hereof is applied in a project to demonstrate that it is reasonable and practical.Through the analysis and comparison, the author considers that it is feasible to apply this model in investment decision-making of composite real estate project, and draws the conclusions as follows:(1) The appliance of this model reduces the influence of subjective factors to the investment decision-making of composite real estate projects, therefore the evaluation is more scientific and truer, the decision-making is more rational as well.(2) This model is reasonable and valid. As a guide and its appliance value, it is helpful to investors or decision-makers to pay attention to the dominating factors.(3) This method embodies the qualities of multi-criteria decision-making and it is convenient to be calculated with linear programming software.
