建筑工程投资决策模型研究

结合灰色关联决策与层次分析法（AHP）建立的新的决策模型结合了灰色关联决策与层次分析法（AHP）各自的优点。建筑工程投资决策往往是一个灰色系统，用灰色关联度决策建立决策模型可以得到准确的结果，再利用层次分析法（AHP）使决策过程中的灰色信息“白色”化，并且可以使决策因素量化，增强了决策的科学性和可靠性。该模型科学、简单而又实用，可用于建筑工程投资方案的选择。

Investment decision model of building project

This article establishes a new decision model by combining the grey incidence decision and analytic hierarchy process(AHP).This model has merits of the analysis on two methods.Investment decision of building project is usually a GREY system,building a decision model by grey incidence decision can get an accurate decision,then analytic hierarchy process(AHP) can make grey information into write information,and it can quantify the factors of decision,so it strengthens the science and credibility of the decision.It is scientific,simple and practical,and can be used in the choice of investment scheme of the building project.
