Because of the shortcomings of the classical rough sets model such as the sensitive to noise often encountered in many real - world applications, the dissertation presents a variable precision and md relation rough sets model from the perspective of rough membership function and micro - difference. not only can the vp - md model overcome the shortcomings of the classical model, but also is consistent with the statistics. this model can extend the application scopes of rough sets and enhance its adaptability
本文從對象的不可分辨關系出發，討論了信息系統的經典粗糙集模型，並針對經典粗糙集模型存在的對噪音敏感等缺陷，提出了基於隸屬度和微差距離的可變精度微差關系（ vp - md ）模型，該模型不僅能夠處理含有噪音的不完全信息系統，其結果也能反映大量數據所滿足的統計規律，使粗糙集理論的應用范圍更廣、適應性更強。
