Fuzzy differential equations
TL;DR: F fuzzy-set-valued mappings of a real variable whose values are normal, convex, upper semicontinuous and compactly supported fuzzy sets in Rn are studied and the existence and uniqueness theorem for a solution to a fuzzy differential equation is given.
Journal ArticleDOI
On fuzzy metric spaces
Osmo Kaleva,Seppo Seikkala +1 more
TL;DR: The distance between two points in a fuzzy metric space is a non-negative, upper semicontinuous, normal and convex fuzzy number.
Journal ArticleDOI
The completion of fuzzy metric spaces
TL;DR: The purpose of this paper is to prove that every Menger space with continuous t-norm has a completion which is unique up to isometry.
Journal ArticleDOI
Fuzzy performance of a coherent system
TL;DR: This paper generalizes the situation further by describing the performance of the system and its components by fuzzy numbers in [0, 1 ], and obtains results which are analogous to those for the reliability of a coherent system.
