摘要
针对信息技术改进项目的选择问题,基于罚函数思想构造偏差模型,提出了不确定广义有序加权对数平均(UGOWLA)算子,分析了其相关性质。然后,提出了一种基于UGOWLA算子的群决策方法,并实现了对信息技术改进备选项目的最优排序。通过对比分析发现本文所提的方法既能充分利用区间不确定信息,又具有明显的项目决策分辨效果,可为信息技术改进项目的决策提供理论支撑。
Aiming at the problems of selection of information technology improvement projects,this paper constructs the deviation model based on the penalty function,and proposes the uncertain generalized ordered weighted logarithmic averaging(UGOWLA)operator,and analyzes its related properties.Then,a group decision making method based on UGOWLA operator is developed to realize the optimal ordering of the information technology improvement projects.Through comparative analysis,it is shown that the proposed method can not only make full use of interval uncertain information,but also have obviously project decision-making discrimination effect.It can provide theoretical support for the decision making of information technology improvement projects.
