A novel CMOS membership function circuit (MBC) is presented. It is based on a linear tunable transconductor proposed in [1] and implements trapezoidal/triangular functions with all parameters (slope, position, width, height and amplitude)independentlyand continuously adjustable. It is suitable to be used in analog fuzzy circuits working in current mode. The computer simulations that verify the ...

This paper proposes a framework for evaluating information technology investments, integrating value chain analysis with activity-based costing and fuzzy logic. The proposed method should be particularly useful for businesses in emerging economies, where an uncertain economic environment is often combined with a lack of dependable, historical accounting data. The framework is illustrated by mea...

In this paper, we investigate an assignment problem in which cost coefficients are triangular intuitionistic fuzzy numbers. In conventional assignment problem, cost is always certain. This paper develops an approach to solve an intuitionistic fuzzy assignment problem where cost is not deterministic numbers but imprecise ones. Here, the elements of the costs (profits) matrix of the assignment pr...

In this paper, we propose, simulated and modelled, first time, a novel fuzzy inference processor capable of handling three types of membership functions together. To implement the proposed inference processor, a novel multi membership function (MMF) MAX-MIN calculator circuit, calculating the matching degree (MD) between three types of membership functions (MF): Gaussian, Trapezoid and Triangul...

Defuzzifier circuit is one of the most important parts of fuzzy logic controllers that determine the output accuracy. The Center Of Gravity method (COG) is one of the most accurate methods that so far been presented for defuzzification. In this paper, a simple algorithm is presented to generate triangular output membership functions in the Mamdani method using the multiplier/divider circuit and...

The present study considers a fuzzy color system in which triangular pyramid-like membership functions are constructed on the RGB color triangle. This system can process a fuzzy input to an RGB system and output the center of gravity of three weights associated with respective grades. Triangular pyramid-like membership functions are applied to the RGB color triangle relationship. By treating th...

Viral infection is a common disease people suffer from, especially when there is a change in season or food habit. One of the common diseases is diarrhea; which may be caused due to viral or bacterial infection. With the revolutionizing technology, medical assistance and disease diagnosis for acute health problems can be done without going to the clinics and hospitals. People are very cautious ...

in this paper, a new structure possessing the advantages of low-power consumption, less hardware and high-speed is proposed for fuzzy controller. the maximum output delay for general fuzzy logic controllers (flc) is about 86 ns corresponding to 11.63 mflips (fuzzy logic inference per second) while this amount of the delay in the designed fuzzy controller becomes 52ns that corresponds to 19.23 m...

This study aims to evaluate the supply aspect of chicken eggs. The Variables used in this research were egg stock, demand, and selling prices with alternatives are adding suppliers, customers, reducing supplier. method using Fuzzy AHp where membership sets fuzzy model Triangular Trapezodial function. results indicate that main priority as a decision support for egss is price customer (0,67), so...
