Parametric approaches to fractional programs: Analytical and empirical study
<p>Fractional programming is used to model problems where the objective function is a ratio of functions. A parametric modeling approach provides effective technique for obtaining optimal solutions of these fractional programming problems. Although many heuristic algorithms have been proposed and …

Low probability-high consequence considerations in a multiobjective approach to risk management
… objective function Second, we develop a fractional programming branch-and-bound approach that IS more robust with respect to the selected value of v. A simple numerical example is provided for the sake of illustration, and the model is also tested using real data Both data acquisition …

Higher moment models for risk and portfolio management
… discussed in the previous chapters, within a fractional programming optimization framework and using a range of popular risk measures, a large scale out-of-sample portfolio application on the point in time constituents of the Dow Jones Industrial Average is presented and discussed, with clear …

Inexact Two-Stage Fuzzy Chance- Constrained Programming for Water Resource Management under Uncertainties
… two-stage fuzzy gradient chance-constrained programming (ITSFGP) method for water resources management is proposed to analyze the tradeoffs between economic development and environmental policies. The uncertainties associated with decision makers’ preferences are expressed as fuzzy sets to …

Resource management for wireless communications : an energy efficiency approach
… most challenging in optimising EE merit is the fractional programming in optimisation field, i.e., non convex programming, which inflicts many difficult tasks for improving network EE performance. As a result, this thesis proposes novel approaches for 5G wireless communication techniques such as …

Efficient radio resource management in integrated terrestrial and non-terrestrial networks
… is a non-convex and mixed integer non-linear programming problem whose complexity is reduced through decomposition into two sub-problems: the user association and resource allocation (UARA) problem and the power allocation (PA) problem. The equivalent UARA problem maximises the total network …

Optimization Models and Analysis of Routing, Location, Distribution, and Design Problems on Networks
… variations of it, are nP-Hard and a 0-1 linear programming model that can be used to solve this problem is developed. This model can accommodate various degrees of disjointedness of the pair of paths, from complete to partial with respect to specific arcs. Next, we examine a minimum-risk routing …
