1、幻灯片1模糊数学绪论用数学的眼光看世界，可把我们身边的现象划分为：1.确定性现象：如水加温到100oC就沸腾，这种现象的规律性靠经典数学去刻画；2.随机现象：如掷筛子，观看那一面向上，这种现象的规律性靠概率统计去刻画;3.模糊现象：如“今天天气很热”，“小伙子很高”，…等等。此话准确吗？有多大的水分？靠模糊数学去刻画。幻灯片2模糊数学绪论年轻、重、热、美、厚、薄、快、慢、大、小、高、低、长、短、贵、贱、强、弱、软、硬、阴天、多云、暴雨、清晨、礼品。共同特点：模糊概念的外延不清楚。模糊概念导致模糊现象模糊数
2、学——研究和揭示模糊现象的定量处理方法。幻灯片3模糊数学绪论l产生1965年，L.A.Zadeh（扎德）发表了文章《模糊集》(FuzzySets，InformationandControl,8,338-353)l基本思想用属于程度代替属于或不属于。某个人属于高个子的程度为0.8,另一个人属于高个子的程度为0.3等.幻灯片4模糊数学绪论l涉及学科模糊代数，模糊拓扑，模糊逻辑，模糊分析，模糊概率，模糊图论，模糊优化等模糊数学分支分类、识别、评判、预测、控制、排序、选择；人工智能、控制、决策、专家系统、医学、土
