Journal of Mathematical Analysis and Applications, 1983 AbstractFuzzy numbers have been introduced by Zadeh in order to deal with imprecise numerical quantities in a practical way. We consider eight classes of fuzzy numbers. We define nine operations for the addition of these fuzzy numbers and we investigate interrelationships between these operations.

Fuzzy Distance of Trapezoidal Fuzzy Numbers [PDF]
Advances in Intelligent Systems Research, 2006 Fuzzy distance is applied on data analysis, classification, and product positioning analysis widely. In this paper, We introduce a fuzzy distance by using graded mean integration representation of generalized fuzzy number and the span of fuzzy number, We also discuss the distance of the linguistic data of “greater or less than x” and “about x”.

Ordered semigroups characterized by (ϵ ϵ vqk)-fuzzy generalized bi-ideals [PDF]
, 2012 In this paper, we introduce a considerable machinery that permits us to characterize a number of special (fuzzy) subsets in ordered semigroups. In this regard, we generalize (Davvaz and Khan in Inform Sci 181:1759-1770 2011) and define (is an element of,

Vendor-Buyers relationship model for deteriorating items with shortages, fuzzy trapezoidal costs and inflation [PDF]
Yugoslav Journal of Operations Research, 2013 In this paper, an integrated inventory model is developed from the perspective of a single vendor and multi-buyers for deteriorating items under fuzzy environment and inflation. In the development of the model, it is assumed that all costs parameters,

On Multidimensional Linear Modelling Including Real Uncertainty
Advances in Electrical and Electronic Engineering, 2014 The theoretical background for abstract formalization of vague phenomenon of complex systems is fuzzy set theory. In the paper are defined vague data as specialized fuzzy sets - fuzzy numbers and there is described a fuzzy linear regression model as a ...
