基于区间概念格的三支决策动态策略调控模型
Dynamic strategy regulation model of three-way decisions based on interval concept lattice and its application
摘要
Abstract
After deeply analyzing the properties of hierarchical structure and interval concept which is constituted by upper and lower bound extensions and intension, in order to achieve the optimal decision solutions by reducing the decision and realizing the dynamic regulation, the interval three-way decisions space is put forward, combining with the three-way deci-sions based on decision-theoretic rough set. Firstly, the positive region, negative region and boundary region are divided by extension of interval concept, and the decision rules, decision metric function and decision loss function of three-way decision based on interval concept are given;secondly, interval three-way decisions concept and the decision which is formed by decision action and decision loss are proposed, and the three-way decision space is built using the construction method of interval concept lattice;thirdly, the dynamic strategy optimizing model based on interval three-way decisions space is established to realize the dynamic decision of practical issues and reduce the loss of incorrect decisions effectively;finally, the example of medical diagnosis shows the correctness and feasibility of this model.关键词
