本文描述了计算机如何使用模糊逻辑来处理工程师词汇表中一些比较模糊的术语：比如非常或稍微。利用模糊逻辑，设计了土壤数据解释专家系统，设计了灾害评估语言。其他应用包括评估土坝的安全性、金属疲劳、结构耐久性、水质、废物管理、废弃矿山的处理、人为错误以及地震工程的许多方面。许多因素在数量上没有很好地定义。例如，专家可以通过调查问卷和评论对建筑物的属性进行数字排序。然后可以使用近似推理技术和模糊逻辑处理这些信息。工程师们现在可以用模糊的方式把他们的意见和判断转化成以前冷冰冰的数字。不确定性可能有一天会用一种结合了概率和模糊集方法的统一理论来处理。
This article describes how using fuzzy logic, computers are coping with some of the vaguer terms in an engineer's vocabulary: ideas like very or slightly. Using fuzzy logic, expert systems are being designed for the interpretation of soil data, and the design of language for damage assessment. Other applications include assessing the safety of earth dams, metal fatigue, structural durability, water quality, waste management, treatment of abandoned mines, human error, and many facets of earthquake engineering. Many factors are not well defined quantitatively. The attributes of a building for example, can be numerically ranked by experts using questionnaires and reviews. This information can then be processed using approximate reasoning techniques and fuzzy logic. Engineers now can put their opinions and judgments into what were previously cold hard numbers by fuzzy means. Uncertainties may one day be dealt with using a unified theory that combines probabilistic and fuzzy set methods.
