Study On Uncertainty Optimum Decision-Making Of Residential Real Estate

All the people having their own houses is the basic living condition for human beings, and it is also the Chinese people's perpetual dream. The residential real estate is different from other commodities greatly because of its basic functions which determinate its own particularity. Therefore, it is important and necessary to give decision-makings for the relevant problems of the residential real estate.The research method of this paper is uncertainty analyze. The uncertainty derives from the difficulty of judging the tendency and the result of such a matter, thus its nature is the information uncertainty. The uncertain information includes fuzzy information, grey information, random information and unknown information. The process of dealing with the uncertain information is the decision-making. It is the process in which people present multiple feasible options in response to the decision-making criterions by using every feasible method, analyzing the subjective and objective conditions systematically and considering the future status, then people selects the appropriate scheme by optimization and evaluation in order to finish the task and solve the problems as planned.For the problems including the urban residential real estate optimum decision-making, the residential real estate appraisal, the optimization and selective preference of residential unit dwelling size, the residential real estate development, the investment and consumption, the evaluation of residential community livability, the prediction of urban residence usable floor area per capita as the sally ports, by establishing the mathematical models and the index system of fuzzy analyze, the decision-making and evaluation, the grey decision-making and prediction, the random uncertainty decision-making under risk, the paper makes use of uncertainty optimum decision-making theory and its calculation methods, gives quantization analyze and optimum decision-making for the example schemes. The paper works out the optimum solution or the satisfying solution; it also justifies the feasibility, the validity and the practicability of the uncertainty optimum decision-making theory and method in the urban residential real estate area.In order to obtain the final optimum solution or the satisfying solution, the paper depends on the example schemes of Beijing urban residential real estate; it is also based on the combination of the example schemes, the mathematical models and the index system. In sum, the paper presents the innovation of applying and improving the mathematical models, establishing the index system and promoting the uncertain information concept.At last, the paper scientifically analyses and systematically generalizes the uncertainty, quantization and mathematic model, the systematicness of decision-making, optimum solution, predicts the future view of the application in the urban and residential real estate field.
