We present a representation of fuzzy numbers and its application to the numerical solution of fuzzy differential (initial value) equations (FDE).

This paper presents three main ideas. They are the Metatheorem, the lattice embedding for sets, and the lattice embedding for algebras.The Metatheorem allows you to convert existing theorems about classical subsets into corresponding theorem about fuzzy subsets. The concept of a fuzzyfiable...

Uncertainties should be considered in any time-cost trade-off problems when minimizing project cost and duration, which leads to the so-called stochastic time-cost trade-off problem. A new approach to investigate stochastic time-cost trade-off problems employing fuzzy logic theory is presented....

Accessing a hospital through the Emergency Department (ED) has become a subject of study for many researchers involved in pricing and resource allocation in healthcare. The research developed in this paper aims to measure the performance of the ED at Sfax Hospital as perceived by its patients....
