基于双论域模糊粗糙集的应急决策模型与方法
The Model and Approach of Emergency Decision-making Based on Fuzzy Rough Set over Two Universes
摘要
Abstract
In this paper , we discuss the theory of fuzzy rough set over two universes with the background of emer -gency decision-making.Then we define a fuzzy rough set model based on fuzzy compatible relation over two uni-verses.By the theory of fuzzy rough set over two universes , the emergency decision-making changes into a rough approximation of a fuzzy decision object on the decision approximation space over two universes .So , we construct the model of emergency decision making based on fuzzy rough set over two universes .We first compute the lower ( upper ) approximation of the fuzzy decision object with respect to the approximation space over two universes , and then present the decision rules by combing the idea of uncertainty decision-making.Moreover, the algorithm of the model is given .This model gives a kind of decision approach to emergency decision-making under the con-dition of incomplete information .Furthermore , it also gives the optimal decision rules with the confidence coeffi-cient by considering the preference of the decision-makers.The proposed method could give a properly descrip-tive of the characters for the emergency decision making with incomplete information , limited recourses of humans and materials and urgently time .Therefore , it can provide a basic theory and a decision approach in practice for emergency decision-making.Finally, the validity of the approach and the applied process is tested by a numeri-cal example .关键词
