Some Applications of Fuzzy Logic in the Selection of Alternatives Considering Multiple Parameters

Professor Amaury A. Caballero
Florida International University
Department of Electrical and Computer Engineering

Abstract: In any decision-making process, it is necessary to evaluate different parameters and disclose the effect they have in the solution in order to optimize it. If the criteria are mathematically quantifiable, a mathematical model may be created for the evaluation process. The application of fuzzy logic is ideal for the solution of this type of problem. There are several common factors when using this method in the optimization of any task. Among them, the characteristics of the membership functions and the criteria used in the optimization as well as the selection of the experts are of fundamental importance. Fuzzy logic is not limited to a specific field of knowledge or industry. It can be applied wherever it is necessary to find the best solution to a problem based on different measurable parameters that somehow impact the result. In this lecture several examples are presented in order to clarify concepts such as the vertical handoff target selection in a heterogeneous wireless network; selection of the best contractor for doing a construction project during a bidding process, and the selection, from a security standpoint, of the best public transportation agency.

Brief Biography of the Speaker: Amaury A. Caballero obtained his Bachelor Degree in Electrical Engineering from the University of Havana, Cuba, earned his Ph.D. in Technical Cybernetics from the Energy Institute of Moscow, Russia, and his Professional Engineer License from the state of Florida, USA. He taught and did research at the Higher Polytechnic Institute of Havana, where he obtained the title of Professor and directed research in the areas of Automatic Control and Robotics. He was also a member of the Higher Scientific Council of the Cuban Academy of Sciences and received awards recognizing his work from the Cuban Ministry of Higher Education and the Technical University of Brno, in Czech Republic, where he also participated in a graduate study and in researches of robotics in conjunction with faculty members. He has been also invited to give presentations about fuzzy logic at the “Universidad de Pamplona” in Colombia, the “Universidad Cat?lica de Santa Mar?a”, and the “Universidad Autonoma” in Peru, the “Universidad Tecnologica Centroamericana” in Honduras, and the “Universidad Autonoma Estatal del Estado de Hidalgo”, in Mexico, where he also imparted a graduate course in fuzzy logic. Dr. Caballero has published two books in the area of automatic control and obtained five certificates of invention in the same area. He also has published research reports, journals papers and proceedings in scientific conferences, totaling over 100 publications. Presently, he is a Senior Lecturer at Florida International University, where he has taught nine electrical engineering undergraduate courses and one graduate course in fuzzy logic, in the department of Electrical and Computer Engineering Also he has conducted in-depth research in the areas of automation applied to construction management, and in the use of rough sets and fuzzy logic for object discrimination in databases, among other applications.
