Method for Risky Multiobjective Group Decision-Making and Its Application

The multiobjective group decision-making problem under risk is common in reality. This paper focuses on the study about risky multiobjective group decision-making problem where the index value is not certain. We give indexes classifying method and index normalizing formula of this type problem. By building objective function that minimizes general weighted distance from every alternative to the relatively best and worst alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, and by building another objective function that minimizes general weighted distance from the optimal membership degree of every decision-maker to every alternative to the group optimal alternative and the group inferior alternative, the optimal membership degree of every decision-maker to every alternative can be obtained, which are both based on probability theory and fuzzy theory. Aftermost a model is established which collects group preferences. This method provides a new idea and     

松花江流域蓄滞洪区方案优选智能决策研究

针对松花江流域防洪工程重要组成部分的蓄滞洪区，基于陈守煜提出的模糊优选BP神经网络模型，引入了遗传算法，提出融入遗传算法的模糊优选神经网络智能决策模型，对松花江流域蓄滞洪区方案优选进行智能决策．该模型既能合理地构造神经网络的拓扑结构，又可加快网络的收敛速度，并能改善网络的全局寻优能力，是对模糊优选BP神经网络模型的进一步发展，同时更对松花江流域蓄滞洪区的优选提供了理论依据．
