The intention of this paper is to illustrate a diligence of fuzzy transportation model in airlift process contrived according to the atmospheric conditions throughout rainy seasons. This paper formula...
A new method for ranking of fuzzy decision making units by FPR/DEA method
data envelopment analysis multi-attribute decision-making
font style='font-size:12px;'>
2010/11/1
The goal of multi-attribute decision-making problems is the ranking of units. In real world, we usually deal with in inexact data. So, there are various ways for ranking of decision making units in fu...
Supply chain model for the retailer's ordering policy under two levels of delay payments in fuzzy environment
Fuzzy numbers Function Principle

Stochastic Fuzzy Hopfield neural networks
font style='font-size:12px;'>
2010/9/20
In this paper, the model of stochastic fuzzy Hopfield neural networks with time-varying delays and impulses (ISFVDHNNs) is established as a modified Takagi-Sugeno (TS) fuzzy model in which the consequ...
“Weird”fuzzy notations: An algebraic interpretation
In fuzzy logic traditionally researchers and practitioners used non-standard notations to describe functions

2010/9/20
Traditionally, fuzzy logic used non-standard notations like m1/x1 + . . . + mn/xn for a function that attains the value m1 at x1, . . . , and the value mn at xn. In this paper, we provide an algebraic...
