Fuzzy Sets and Fuzzy Logic Brian T. Luke, Ph.D. ( btluke@aol.com LearningFromTheWeb.net This section contains an overview of Fuzzy Sets and Fuzzy Logic. This information is taken from Fuzzy Sets and Fuzzy Logic: Theory and Applications , George J. Klir and Bo Yuan, Prentice Hall, NJ (1995) Given three fuzzy sets (A, B, C), they each have associated membership functions (Ma, Mb, Mc). Since there is no ambiguity, A can be interchanged with Ma, B with Mb, and C with Mc. Therefore, throughout this text, A represents both a fuzzy set and its associated membership function. If x is the parameter or value that determines which set(s) the data belongs to, the membership functions can be written as A(x), B(x), and C(x). An alpha-cut of the membership function A (denoted aA) is the set of all x such that A(x) is greater than or equal to alpha (a). Similarly, a strong alpha-cut (denoted a+A) is the set of all x such that A(x) is strictly greater than alpha (a). Mathematically, "That is, the alpha-cut (or the strong alpha-cut) of a fuzzy set A is the crips set aA (or the crisp set a+A) that contains all the elements of the universal set X whose membership grades in A are greater than or equal to (or only greater than) the specified value of alpha." aA and a+A are crisp sets because a particular value x either is or isn't in the set; there is no partial membership.

The classification is made in order to join the papers that make reference to a specific fuzzy logic area. CLASSIFIED REVIEW INFORMATION Recentely, numerous papers and applications combining fuzzy logic (FL) and genetic algorithms (GAs) have become known, and there is an increasing interest in the integration of these two topics. The present bibliography collects a big set of references in this growing area, althought unfortunatelly they are not all the possible. The references marked by don't belong to our paper collection, obtaining them from the references of other publications or by authors. Some of the references are incomplete because either we have earlier versions before to be published or we have got them incomplete. Comments, corrections, papers and references for mantaining the file are welcome.

R EASON * March 1999 Fuzzy Logic By Lynn Scarlett Principles for a Free Society: Reconciling Individual Liberty with the Common Good , by Richard Epstein, Reading, Mass.: Perseus Books, 368 pages, $27.50 These days, fashionable environmentalists sound like neoclassical economists. They chatter about the need to "internalize externalities," pressing for eco-taxes on greenhouse gases, sulfur dioxide emissions, wasteful packaging, noise, fumes, mine tailings, chemical consumption, and any other perceived "bad" that captures their attention. This notion of externalities as a form of "market failure" opens up endless possibilities for state intervention. The possibilities are endless because, as Richard Epstein observes in his latest book, Principles for a Free Society , "every action, every transaction has innumerable consequencespositive and negativethat spill over to other people." Leaves from one person's tree fall onto another's yard; a car door slams across the road, jolting someone from his midday reverie; a plane flies 30,000 feet overhead, leaving an unnatural scratch upon the sky; neon pink trim around the windows of a house offends a neighbor's sense of aesthetics and propriety. Many staunch champions of property rights and market institutions have inadvertently aided and abetted this undisciplined demand to internalize externalities. They have done so by confidently asserting two absolute principles: the "do no harm" principle and the right to private property. Like their counterparts in the modern environmental movement, they have reduced complex matters of human interaction to bumper-sticker phrases. Under this absolutism, writes Epstein, all manner of "harms"from the neighbor's falling leaves to slamming car doors"cry out for relief."

Ress TABLE OF CONTENTS INTRODUCTION FUZZY SET THEORY FUZZY MOLECULAR MODELING Fuzzy Lines ... References Since fuzzy logic is, by definition, imprecise, it is a natural means of representing the imprecision of lattice parameters and bond angles. Fuzzy lattice parameters are created by collecting parameter values from the literature. From the minimum, maximum, and average of these parameter values, a fuzzy number is created that represents the imprecision in that parameter. Then, through the use of fuzzy arithmetic operators and recently developed fuzzy trigonometric functions, fuzzy atom locations within the unit cell and bond angles can be calculated. The benefit of using fuzzy logic in this manner is that it directly enables representation and calculation with the imprecision found in chemical compounds, which arises from measurement variability due to measurement error, structural defects, and thermal and vibrational characteristics.

Fuzzy Logic Abstract This paper gives a general overview of fuzzy logic theory. It describes the concepts of fuzzy sets and operations used in their manipulation, developed by Lofti Zadeh in 1965. The paper gives examples of the fuzzy logic applications, with emphasis on the field of artificial intelligence. Fuzzy Logic "When Theseus returned from slaying the Minotaur, says Plutarch, the Athenians preserved his ship, and as planks rotted, replaced them with new ones. When the first plank was replaced, everyone agreed it was still the same ship. Adding a second plank made no difference either. At some point, the Athenians may have replaced every plank in the ship. Was it a different ship? At what point did it become one?" [1] The classical logic relies on something being either True or False. A True element is usually assigned a value of 1, while False has a value of 0. Thus, something either completely belongs to a set or it is completely excluded from it. The fuzzy logic broadens this definition of membership. The basis of the logic are fuzzy sets. Unlike in "crisp" sets, where membership is full or none, an object is allowed to belong only partly to one set. The membership of an object to a particular set is described by a real value from the range between and 1. Thus, for instance, an element can have a membership value 0.5, which describes a 50% membership in a given set. Such logic allows a much easier application of many problems that cannot be easily implemented using classical approach.

Back home Vojislav KECMAN The MIT Press, Cambridge, MA, 2001 ISBN 0-262-11255-8 608 pp., 268 illus., This is the first textbook that provides a thorough, comprehensive and unified introduction to the field of learning from experimental data and soft computing. Support vector machines (SVMs) and neural networks (NNs) are the mathematical structures, or models, that underlie learning, while fuzzy logic systems (FLS) enable us to embed structured human knowledge into workable algorithms. The book assumes that it is not only useful, but necessary, to treat SVMs, NNs, and FLS as parts of a connected whole. The theory and algorithms are illustrated by 47 practical examples, as well as by 155 problem sets and simulated experiments. This approach enables the reader to develop SVMs, NNs, and FLS in addition to understanding them. The book also presents three case studies on: NNs based control, financial time series analysis, and computer graphics. A solutions manual and all of the MATLAB programs needed for the simulated experiments are available.

Ruspini, P. Bonissone and W. Pedrycz, Eds. (Oxford Univ. Press and IOP Press, 1998). Abstract The development of techniques for autonomous navigation constitutes one of the major trends in the current research on mobile robotics. In this case study, we discuss how fuzzy computation techniques have be used in the SRI International mobile robot Flakey to address some of the difficult issues posed by autonomous navigation: (i) how to design basic behaviors; (ii) how to coordinate behaviors to execute full navigation plans; and (iii) how to use approximate map information. Our techniques have been validated in both in-house experiments and public events. The use of fuzzy logic has resulted in smooth motion control, robust performance in face of errors in the prior knowledge and in the sensor data, and principled integration between different layers of control.

Investors Company Products News ... Contacts A Clear future for fuzzy logic For many years, fuzzy logic has been an attractive idea to designers of industrial, consumer and automotive products. However, achieving the right balance between cost and performance has not always been easy. Fuzzy algorithms can be executed on low-cost conventional microcontrollers but as these have architectures that were not designed to handle fuzzy logic, the software overhead often makes the performance inadequate. Dedicated fuzzy processor chips can meet the most demanding performance needs but are often too expensive for cost-sensitive applications, particularly as a separate microcontroller is often required anyway to handle interfacing with sensors, displays and other peripherals. The latest fuzzy device from ST bridges the gap between these two extremes: all the benefits of fuzzy logic can be exploited in a cost-effective single-chip controller that meets the needs of a wide range of low and medium-end control applications. In volume, the cost is around $2 in the OTP version. As the family name implies, the ST52x301 DuaLogic (TM) microcontroller combines a fuzzy logic core, a Boolean ALU and a set of peripheral functions chosen to reflect real applications needs such as A/D conversion and driving external triacs.

FUZZY LOGIC DESIGN TOOLS The fuzzy system development environment Xfuzzy integrates a set of tools that ease the user to cover the several stages involved in the design process of fuzzy logic-based inference systems, from their initial description to their final implementation. The sections of this page are linked with the several versions of the environment, with our related scientific publications, and with some didactic material. This new version of Xfuzzy is based on a new specification language (XFL3) which extends the advantages of its predecessor, allowing the use of linguistic hedges as well as new fuzzy operators defined freely by the user. New CAD tools have been included to ease the edition of operator sets and hierarchical systems, to generate 2- and 3-dimmensional graphic outputs, and to monitor the inference process. The tool that applies supervised learning has been quitely renewed so as to include new algorithms as well as pre- and post-processing techniques to simplify the obtained rule bases. Xfuzzy 3.0 has been enterely programmed in Java. Hence, it can be executed on any platform with JRE (Java Runtime Environment) installed. The version 2.1 of Xfuzzy, based on the specification language XFL, includes several CAD tools to describe, verify and synthesize (into software or hardware) fuzzy systems. This version can be compiled and executed in Unix-like operating systems with the X Window system. It can be also executed in MS-Windows by using the environment

138. 'Fuzzy' Logic Article Researchers explore agricultural applications of new computer software technology. http://cati.csufresno.edu/upda/95/winter/story1.html

- Winter 1995 "Update" Newsletter Article - 'Fuzzy' logic Researchers explore agricultural applications of new computer software technology From CATI Publication #950101 A CSU, Fresno Industrial Technology professor is exploring agricultural applications of a new technology that mimics human thought patterns in controlling industrial equipment operations. Professor Matthew Yen's research is focused on the application of "fuzzy logic" in the control of equipment such as heaters, motors, pumps, valves and sprinklers used in the food processing industry and other automated agricultural operations. In order to automate these processes, temperature, motor speed, liquid level, pressure, humidity, flowrate and other variables must be constantly monitored and adjusted according to prescribed schedule. Simple on/off controls may overshoot, undershoot or fluctuate around the desired setting values. "Fuzzy logic control enables the system to tightly follow the control prescription in a smooth manner," Yen said. "It is an emerging technology widely used by the appliance industry and process industries in Japan." The concept fuzzy logic controls was first proposed in 1965 by L. A. Zadeh and is based on the "fuzzy estimation" or "chunking" of human thinking rather than precise mathematical computation. A control system based on fuzzy logic has the following advantages: 1) It is easy to implement since it uses "if-then" logic instead of sophisticated differential equations; 2) It is understandable by people who do not have process control backgrounds; and 3) Software and hardware tools are readily available for applying this technology.
