The topic of the work for Master’s degree is: “The formation of fuzzy logic links and structural models”. The purpose of this work is to design a calculator, which would make arithmetic operations with the elements of fuzzy logic. This programme would allow to make such operations with fussy logic elements: addition (+), substraction (–), multiplication (×), division ( : ). Five main parts are presented in the work: analytical one, designed one, the documentation of the consumer, the evaluation of fuzzy logic calculator, the conclusions. In the first part the analysis of fussy arithmetic operation is made, the operations which can be applied in designing are given. In the second part the requirements of the consumer are analyzed and functional requirements are given. The specification of the system is made. The schedule of the project performance is set. The measures of project hazard and prevention are set. The testing, which has been made is described. The plan of system developing is presented. In the third part the documentation of consumer is written. In the fourth part a thorough analysis of calculator working is made, its advantages and disadvantages, fields of application are singled out. The fifth part is the conclusions. Fussy logic makes it possible to achieve much better management characteristics than by traditional methods. One may use the designed calculator by teaching the course of “Calculating methods with indefinite sets” and will help students to master... [to full text]
