Trapezoidal intuitionistic fuzzy prioritized aggregation operators and application to multi-attribute decision making
Volume 12, Issue 4 , July and August 2015, Pages 1-32
Abstract
In some multi-attribute decision making (MADM) problems, various relationships among the decision attributes should be considered. This paper investigates the prioritization relationship of attributes in MADM with trapezoidal intuitionistic fuzzy numbers (TrIFNs). TrIFNs are a special intuitionistic ... Read MoreAn Optimization Model for Multi-objective Closed-loop Supply Chain Network under uncertainty: A Hybrid Fuzzy-stochastic Programming Method
Volume 12, Issue 4 , July and August 2015, Pages 33-57
Abstract
In this research, we address the application of uncertaintyprogramming to design a multi-site, multi-product, multi-period,closed-loop supply chain (CLSC) network. In order to make theresults of this article more realistic, a CLSC for a case study inthe iron and steel industry has been explored. The ... Read MoreDeveloping new methods to monitor phase II fuzzy linear profiles
Volume 12, Issue 4 , July and August 2015, Pages 59-77
Abstract
In some quality control applications, the quality of a process or a product is described by the relationship between a response variable and one or more explanatory variables, called a profile. Moreover, in most practical applications, the qualitative characteristic of a product/service is vague, uncertain ... Read MoreEffects of Project Uncertainties on Nonlinear Time-Cost Tradeoff Profile
Volume 12, Issue 4 , July and August 2015, Pages 79-100
Abstract
This study presents the effects of project uncertainties on nonlinear time-cost tradeoff (TCT) profile of real life engineering projects by the fusion of fuzzy logic and artificial neural network (ANN) models with hybrid meta-heuristic (HMH) technique, abridged as Fuzzy-ANN-HMH. Nonlinear time-cost relationship ... Read MoreOn the compactness property of extensions of first-order G"{o}del logic
Volume 12, Issue 4 , July and August 2015, Pages 101-121
Abstract
We study three kinds of compactness in some variants of G"{o}del logic: compactness,entailment compactness, and approximate entailment compactness.For countable first-order underlying language we use the Henkinconstruction to prove the compactness property of extensions offirst-order g logic enriched ... Read MoreRemarks on completeness of lattice-valued Cauchy spaces
Volume 12, Issue 4 , July and August 2015, Pages 123-132
Abstract
We study different completeness definitions for two categories of lattice-valued Cauchy spaces and the relations between these definitions. We also show the equivalence of a so-called completion axiom and the existence of a completion. Read MoreFixed fuzzy points of generalized Geraghty type fuzzy mappings on complete metric spaces
Volume 12, Issue 4 , July and August 2015, Pages 133-146
Abstract
Generalized Geraghty type fuzzy mappings oncomplete metric spaces are introduced and a fixed point theorem thatgeneralizes some recent comparable results for fuzzy mappings incontemporary literature is obtained. Example is provided to show thevalidity of obtained results over comparable classical results ... Read MoreQuasi-contractive Mappings in Fuzzy Metric Spaces
