Variable multiple integration decision-theoretic rough sets model and its application in vehicle safety assessment

Abstract

Analyze the deficiency of rough set decision-making cost matrix to put forward a kind of multiple fusion rules of cost matrix. Adjust parameter values to make fusion rules in accordance with the application requirement of specific cases. And then establish a multiple integration Decision-Theoretic Rough Sets model. This describes the definition of a decision domain distribution and proposes a method of attribute reduction and decision rule based on differential matrix. The example analysis of the safety evaluation of the Vehicle verifies the feasibility and effectiveness of the method.
