A fuzzy concept is a concept of which the boundaries of application can vary considerably according to context or conditions, instead of being fixed once and for all. [1] This means the concept is * vague * in some way, lacking a fixed, precise meaning, without however being unclear or meaningless altogether. [2] It has a definite meaning, which can become more precise only through further elaboration and specification, including a closer definition of the context in which the concept is used.

A fuzzy concept is understood by scientists as a concept which is "to an extent applicable" in a situation, and it therefore implies gradations of significance. The best known example of a fuzzy concept around the world is an amber traffic light , and indeed fuzzy concepts are widely used in traffic control systems. [3] Engineers, statisticians and programmers nowadays often represent fuzzy concepts mathematically using fuzzy variables, fuzzy sets and fuzzy values. Since the 1970s, the use of fuzzy concepts has risen gigantically in all walks of life.

Logic (from the Ancient Greek : λογική , * logikḗ* [1] ), originally meaning "the word" or "what is spoken" (but coming to mean "thought" or "reason"), is generally held to consist of the systematic study of the form of arguments. A valid argument is one where there is a specific relation of logical support between the assumptions of the argument and its conclusion. (In ordinary discourse, the conclusion of such an argument may be signified by words like * therefore* , * hence* , * ergo* and so on.)

There is no universal agreement as to the exact scope and subject matter of logic (see § Rival conceptions , below), but it has traditionally included the classification of arguments, the systematic exposition of the ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''logical form'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' common to all valid arguments, the study of inference , including fallacies , and the study of semantics , including paradoxes. Historically, logic has been studied in philosophy (since ancient times) and mathematics (since the mid-1800s), and recently logic has been studied in computer science , linguistics , psychology , and other fields.

This application lets readers explore data and other quantitative results submitted with the article, providing insights into and access to data that is otherwise buried in plots.

Since its launching in 1978, the journal Fuzzy Sets and Systems has been devoted to the international advancement of the theory and application of fuzzy sets and systems. The theory of fuzzy sets now encompasses a well organized corpus of basic notions including (and not restricted to) aggregation operations.
