The paper identifies the strategic effects of learning-by-doing in presence of unintended spillovers of production experience. In a two-stage game an incum...

Pricing Asian options based on the arithmetic average, under the Black and Scholes model, involves estimating an integral (a mathematical expectation) for w...

We pursue the study of concavity cuts for the disjoint bilinear programming problem. This optimization problem has two equivalent symmetric linear maxmin r...

This paper focuses on accelerating strategies used in conjunction with column generation to solve Vehicle Routing and Crew Scheduling problems. We describ...

Over the last thirty-five years several heuristics have been proposed for the <i>Vehicle Routing problem</i>. This article reviews the main classical heuris...

In recent years several <i>metaheuristics</i> have been proposed for the <i>Vehicle Routing Problem</i>. This article reviews the main metaheuristics for th...

The well-known Undirected Rural Postman Problem is considered and a binary linear problem using new dominance relations is presented. Polyhedral properties ...

Let <i>G</i> be a simple graph and <i>C</i> and <i>D</i> two proper colourings of <i>G</i>. The problem of colour switching consists of finding a sequence ...

We study the solution of combinatorial problems with the column generation techniques when there is a very large number of both variables and constraints. ...

This note determines a rule to share a surplus gained when two countries or regions agree to coordinate their policies to reduce downstream pollution. An in...

In this paper we deal with the problem of how to expand MANs (Metropolitan Area Networks) in a cost-effective way. We first propose a mathematical programmi...

This paper deals with the problem of how to update telecommunication networks economically. We first propose a mixed integer programming model that includes...

The paper considers two neighboring countries wishing to make a joint effort to control pollution emission. We use a differential game model that includes ...

Treatment of imprecise probabilities within the probabilistic satisfiability approach to uncertainty in knowledge-based systems is surveyed and discussed. ...

In this article we propose a mixed 0-1 linear programming model for the topological network design problem with modular switches such as the ones that will ...

This paper aims to provide an answer to the still open question, namely who should, if any, lead a marketing channel? To achieve this objective, we conside...

We consider an asymmetric duopoly producing a homogeneous commodity and facing a competitive demand. Our model incorporates two asymmetries. The first one i...

Coupling with the Modified-Grid Unconstrained Optimization Algorithm we introduced in our previous paper (Cheung and Ng, 1995), we have been able to develop...

The spatially inhomogeneous smoothness of the non-parametric density or regression-function to be estimated by non-parametric methods is often modelled by B...

Il est généralement reconnu que le processus de découpage électoral doit être à l'abri du gerrymandering et de l'intervention politique. L'utilisation de mé...
