双论域上量化粗糙集模型及应用
Quantitative rough set model over two universes and its application
摘要
Abstract
The double quantization method can describe the uncertainty nature of decision object in approximate space.In this paper,the basic model of dual quantization rough set is discussed under the framework of double domain.The back-ground and significance of the double-domain quantization rough set are given by the practical decision-making problem. The basic definition of the double-domain quantization rough set is given by combining the classical variable precision rough set and the degree rough set.Furthermore,the basic properties of the upper and lower approximations and the rela-tionship with the existing rough set model are systematically discussed,and the matrix calculation method is given.Finally, based on the established theoretical model and method,it gives the application of dual-domain quantization rough set in disease diagnosis decision-making.The application of theoretical model is illustrated by an example.关键词
