基于可信性理论,提出一类新的带有模糊约束的房地产投资随机期望值模型来处理房地产经济中的不确定性信息.另一方面,通过目标函数和可信性函数的一些性质将提出的房地产投资问题转化为一个等价的线性形式,从而可以利用经典的线性规划算法进行求解.最后,给出一个房地产投资问题的实例并通过Lindo软件进行求解. Based on the credibility theory, a new type of stochastic expectation model of real estate investment with fuzzy constraints is proposed to deal with the uncertainty of the real estate economy.On the other hand, some properties of the objective function and the credibility function will be proposed The problem of real estate investment is transformed into an equivalent linear form, which can be solved by classical linear programming algorithm.Finally, an example of real estate investment is given and solved by Lindo software.
