基于相对熵原理的大型工程项目交互式多属性群决策方法研究

Study on Interactive Multi-Attribute Group Decision Making Method for Large-Scale Projects Based on Relative Entropy

由于大型工程决策涉及多元决策主体和多层次决策目标,不可避免会引起冲突。如何有效集结决策群体的偏好以协调决策者之间的冲突,是研究的主要目的。本文基于不确定多属性群决策理论的研究视角,分别利用交互式的线性规划模型和优化原理求解属性权重和专家权重,然后基于相对熵原理集结决策群体的不同偏好信息。

Since decision making of large-scale construction project involves a wide range of decision makers and multi-level objectives,it may inevitably cause conflict.Therefore,how to aggregate group＇s preference effectively to coordinate conflict among participants is the major purpose of this paper.Firstly,a new method to determine attribute weights and experts＇ weights is proposed making use of interactive linear programming and optimization theory based on the uncertain multiple attribute theory.Secondly,we apply the theory of relative entropy to aggregate participants＇ preference about alternatives into a single consensus or compromise one.Finally,a numerical example of project alternatives selection is used to demonstrate the feasibility and practicability of the presented approach.
