Scheduling often plays an important role in vehicle routing. This paper describes several applications in which the author has been involved in recent years...

We introduce a Laplacian and a signless Laplacian for the distance matrix of a connected graph, called the <i>distance Laplacian</i> and <i>distance signless...

One of the major results announced in the static literature on the coordination of pricing decisions in bilateral monopolies states that vertical integrati...

Consider a scale that accepts three marbles of different weights. The scale only ranks the marbles, by indicating the heaviest, the lightest and the middle ...

We consider a differential game with a corrupt government and civil society as its players. We characterize open-loop and feedback Nash equilibria and find...

We consider multi-antenna base stations using orthogonal frequency-division multiple access and space division multiple access techniques to serve single-a...

In this paper we introduce the discrete time window assignment vehicle routing problem. This problem consists of assigning a single time window from a ...

We derive conditions on the functions \(\varphi\), \(\rho\), \(v\) and \(w\) such that the 0-1 fractional programming problem`(\max\limits_{x\in {0...

This paper studies the pricing strategies of firms belonging to a vertical channel structure where optional contingent products are sold. Optional continge...

The purpose of this paper is to study the periodic arc routing problem when the arcs of a network behave as customers, and sufficient material is delivered s...

In many situations, such as art auctions, privatization of public assets and allocation of television airwaves to wireless carriers, the value of the objec...

We consider a two-player differential game of international emissions to represent the interactions between two groups of countries, namely, developed and ...

Interior-point methods feature prominently among numerical methods for inequality-constrained optimization problems, and involve the need to solve a sequ...

This paper presents a decomposition approach for solving a variant of the Routing and Wavelength Assignment (RWA) problem, in which all connection requests a...

We model the role of the world's forests as a major carbon sink and consider the impact that forest depletion has on the accumulation of CO₂ in ...

Application of the dispersion models in order to address the cannibalization phenomenon within franchised chains is a new approach. In this work we have deve...

Community detection in networks has been studied extensively in the last decade. Many criteria, expressing the quality of the partitions obtained, as well ...

Reduced RLT constraints are a special class of Reformulation-Linearization Technique (RLT) constraints. They apply to nonconvex (both continuous and mixed-...

Given a set of entities, cluster analysis aims at finding subsets, also called clusters or communities or modules, entities of which are homogeneous and well...

We consider a two-period closed-loop supply chain (CLSC) game where a remanufacturer appropriates of the returns' residual value and decides whether to exc...
