采用极大熵方法配置参数，构建了考虑体外循环的GERT网络模型，研究投资决策参量的相关参数的函数关系、运算法则及确定方法，提出了考虑体外循环的GERT网络模型求解算法。将该GERT网络模型应用于房地产市场领域，研究房地产市场中各参与主体之间的投资决策流动系统。结果显示，利用该GERT网络模型能充分反映房地产市场中各部门之间、房地产市场部门与体外环境部门之间的交互影响关系，可得到科学合理的量化结论。

This paper constructs a GERT network model with extracorporeal feedback loop through using the method of maximum entropy to make the parametric configuration, and analyzes the function relation and the operating regulation of parameters about investment decision. Then it provides an analytic algorithm of this GERT network model. And it applies this GERT network model to study the investment decision flowing system of participants in real estate market. The result shows the mutual influence relationship among sections in real estate market, and the mutual influence relationship between sections in real estate market and sections in extracorporeal feedback loop could be reflected by this GERT network model.
