We propose a deterministic, discrete-time, finite-horizon oligopoly model to investigate investment and production equilibrium strategies, in a setting where...

In the <i>Vehicle Routing Problem with Deliveries, Selective Pickups and Time Windows</i>, the set of customers is the union of <i>delivery customers</i> and...

During the last three decades, the computer has been widely used in spectral graph theory. Many results about graph eigenvalues were first conjectured, and i...

The <i>improved primal simplex</i> (IPS) method has been proposed by Elhallaoui et al. (2008). We rewrite the theory of IPS for a cold start with an initial ...

This paper focuses on the use of different memory strategies to improve multistart methods. A network design problem in which the costs are given by discrete...

This work studies multi-objective optimization <i>(MOP)</i> of nonsmooth functions subject to general constraints. We first present definitions and optimalit...

We study a dynamic Cournot game with capacity accumulation under demand uncertainty, in which the investment is perfectly divisible, irreversible, and produc...

In-house production or outsourcing are important strategic decisions for planning production and capacity in business organizations. Outsourcing to overseas ...

A Public Disclosure Program (PDP) is compared to a traditional environmental regulation (exemplified by a tax/subsidy) in a simple dynamic framework. A PDP a...

It is observed that mutations in the formulations of test problems over time are not infrequent. Ensuing problems are illustrated with examples from geometri...

Finding maximum likelihood parameter values for Finite Mixture Model (FMM) is often done with the Expectation Maximization (EM) algorithm. However the choice...

This paper studies sustainability from both an economic and environmental perspective. We concentrate in two separate but interlinked environmental issues: t...

The Dutch railway network experiences about three large disruptions per day on average. In this paper, we present an algorithm to reschedule the crews when s...

A recent paper of Tuy and Hoai-Phuong published in <i>JOGO</i> (2007) 37:557--569 observes that there are errors in the reformulation of a signomial geometr...

The <i>Generalized Vehicle Routing Problem</i> (GVRP) is an extension of the classical <i>Vehicle Routing Problem</i> (VRP) in which the vertex set is partit...

It is now accepted that climate change is due to the cumulative and joint effect of multiple atmospheric trace constituents. The importance of adopting a com...

Should manufacturers of durable products such as automobiles and household appliances offer cash rebates to all consumers at the time of purchase, or offer t...

<p>The class of Mesh Adaptive Direct Search (MADS) algorithms is designed for the optimization of constrained black-box problems. The purpose of this paper i...

This paper deals with the design of equilibrium solutions with coupled constraints in dynamic games of greenhouse gas (GHG) emission abatement. Self-enforcin...

This work presents an exact branch-cut-and-price algorithm for the vehicle routing problem with time windows (VRPTW) where the well-known clique inequalities...
