设备的复杂性,使获得故障信息中含有随机信息、模糊信息、未确知信息、灰信息等不确定性信息。本文分析了联合诊断中存在的不确定性信息,并提出用粗集理论处理联合诊断技术中的不确定性的数学方法理论,克服单一监测手段的局限性。
Fault information available contains random, fussy, uncertain or grey information because of the complexity of equipment. The paper analyzes uncertain information in joint diagnosis and presents a theoretical method that overcomes the limitation of the single monitoring method based on the rough sets theory.
