基于信息熵模型的绿色节能建筑投资风险决策应用

Risk Decision Making of Green Energy-efficient Investment in Construction with Information Entropy Model

由于目前绿色节能建筑在投资阶段风险决策至关重要,因此,基于信息熵的应用理论和方法,提出了一种基于信息熵模型投资风险决策以及评估指标权重的决策确定方法,同时对信息熵理论所提出的信息熵值越大则对应的系统越混乱,信息熵越小则对应的系统越有序的已有结论进行了科学有效验证。这种方法的基本思想大致为:首先通过建立绿色节能的风险决策信息熵模型,采用专家打分法进行打分,其次形成风险评估矩阵,之后引入指标权重,经过归一化处理,去除量纲,最终使用信息熵模型计算熵值和熵权,并进行所识别风险因素的主次排序,来进行风险决策,为开发商开发绿色节能建筑提供了一种可以指标量化、科学合理的风险投资决策模型方法。

Due to the important of building venture investment decisions at the current green energyefficient stage,therefore,based on information entropy theory,a method for determining an investment risk is put forward,which is based on information entropy model and the evaluation index weights. At the same time,the inclusion is testified more scientific,which the system information entropy is greater,the system is more chaos; the system information entropy is smaller,the system is more orderly. The corresponding information entropy theory is also verified scientifically and effectively. The basic idea of this method is roughly： firstly,through the creation of green energy risk decision information entropy model,the expert scoring method is used,then formation of a risk assessment matrix is induced,after the introduction of the index weight,eventually normalization to remove dimension,information entropy model is used to calculate the entropy value and entropy weight which are used to prioritizes the identification of risk factors and make risk decisions for developers to provide a green energy-efficient building indicators venture investment decision model method to quantify.
