区间值模糊推理在风湿疾病诊断上的应用

摘要

疾病诊断专家系统是应用人工智能技术来模拟医生诊断疾病的思维过程的一种程序系统.对于复杂的疾病诊断,其推理模型均为多重多维的.风湿性疾病是一类常见疾病,危害(5D)是相当严重的.本文将区间值模糊推理应用在风湿性疾病诊断的推理中,区间值隶属度能更容易的描述模糊信息的不确定性,并且区间值模糊推理方法可以减少推理过程中模糊信息的丢失.%Disease diagnosis expert system is a program system based on artificial intelligence technology which simulates the doctor diagnosis of diseases of the thinking process.In case of considering of complex disease diagnosis,the reasoning model is mostly multiple and multidimensional.Rheumatic is a kind of common disease,its harm(5D) is very serious.In this paper interval-valued fuzzy reasoning is applied in diagnosis of rheumatic disease reasoning.Interval-valued membership can describe fuzzy information more easily,and interval-valued fuzzy reasoning method can reduce the loss of information in the process of reasoning fuzzy.
