An application of decision theory on the approximation of a generalized Apollonius-type quadratic functional equation

Journal of Inequalities and Applications
To make better decisions on approximation, we may need to increase reliable and useful information on different aspects of approximation. To enhance information about the quality and certainty of approximating the solution of an Apollonius-type quadratic

Solving the Fornberg–Whitham Model Derived from Gilson–Pickering Equations by Analytical Methods

Axioms
This paper focuses on obtaining traveling wave solutions of the Fornberg–Whitham model derived from Gilson–Pickering equations, which describe the prorogation of waves in crystal lattice theory and plasma physics by some analytical techniques, i.e., the ...

Product Line Potential Analysis [PDF]

, 2004
A Product Line Potential Analysis enables us to make a quick decision as to whether the product line approach (PLA) is suitable for a given set of products and target market. The PLA framework offers no support for this as yet.

A mixed-integer optimization approach to E-tailing supply chain resilience through substitution and transshipment

Supply Chain Analytics
Efficient order fulfillment in e-tailing networks is increasingly challenged by inventory shortages, dispersed fulfillment centers, and heterogeneous customer preferences. This study develops a mixed-integer programming model that jointly optimizes order

Properties of the forgotten index in bipolar fuzzy graphs and applications

Scientific Reports
Topological indices are the numbers that remain constant under graph automorphism. Topological indices describe a network’s connectivity, structure, and topological characteristics. These indices have many applications in crisp graphs.

Study on multidimensional fuzzy graphs through modified partial ordering

Mathematics in Applied Sciences and Engineering
This paper introduces the concepts of multidimensional fuzzy graphs and edge-powered multidimensional fuzzy graphs, which employ a hybrid structure that combines multidimensional fuzzy sets and graphs. This study redefines the axioms of multidimensional

Multicriteria Group Decision Making Based on TODIM and PROMETHEE II Approaches with Integrating Quantum Decision Theory and Linguistic Z Number in Renewable Energy Selection

Mathematics
Decision makers (DMs) are often viewed as autonomous in the majority of multicriteria group decision making (MCGDM) situations, and their psychological behaviors are seldom taken into account.
