“需要模糊逻辑吗？“是一个历史悠久，讨论热烈的问题。关于模糊逻辑有很多误解。模糊逻辑不是模糊的。基本上，模糊逻辑是一种不精确和近似推理的精确逻辑。更具体地说，模糊逻辑可以被看作是两个显着的人类能力的形式化/机械化的尝试。第一，在信息不精确、不确定、不完整、相互矛盾、真理不确定、可能性不确定的环境中--简而言之，在信息不完善的环境中--进行匡威、推理和做出理性决策的能力。第二，在没有任何测量和计算的情况下执行各种各样的身体和精神任务的能力（Zadeh 1999，2001）。事实上，模糊逻辑的主要贡献之一是它的高精度。模糊逻辑不仅仅是一个逻辑系统。它有许多方面。主要方面是：逻辑，模糊集理论，认识和关系。模糊逻辑的大多数实际应用都与其关系方面有关。在本文中，模糊逻辑被视为在一个非标准的角度。从这个角度来看，模糊逻辑的基石及其主要的区别特征是：分级、粒化、精确化和广义约束的概念。
"Is there a need for fuzzy logic?" is an issue which is associated with a long history of spirited discussions and debates. There are many misconceptions about fuzzy logic. Fuzzy logic is not fuzzy. Basically, fuzzy logic is a precise logic of imprecision and approximate reasoning. More specifically, fuzzy logic may be viewed as an attempt at formalization/mechanization of two remarkable human capabilities. First, the capability to converse, reason and make rational decisions in an environment of imprecision, uncertainty, incompleteness of information, conflicting information, partiality of truth and partiality of possibility- in short, in an environment of imperfect information. And second, the capability to perform a wide variety of physical and mental tasks without any measurements and any computations (Zadeh 1999, 2001). In fact, one of the principal contributions of fuzzy logic-a contribution which is widely unrecognized-is its high power of precisiation. Fuzzy logic is much more than a logical system. It has many facets. The principal facets are: logical, fuzzy-set-theoretic, epistemic and relational. Most of the practical applications of fuzzy logic are associated with its relational facet. In this paper, fuzzy logic is viewed in a nonstandard perspective. In this perspective, the cornerstones of fuzzy logic-and its principal distinguishing features-are: graduation, granulation, precisiation and the concept of a generalized constraint.
