The problem of exogenity in economics is a highly relative one. For example in microeconomics (production theory or consumer theory) quantities are exogeneo...

This paper describes an integer linear programming algorithm for vehicle routing problems involving capacity and distance constraints. The method uses const...

Nous étudions dans cet article la possibilité d'effectuer le couplage entre un modèle de simulation de la demande énergétique (MEDEE-3-QUEBEC) et un modèle d...

In this article, we examine the use of Lagrangian relaxation to obtain a lower bound on the minimum fleet size for the m-TSP with time window constraints on ...

This paper provides an integer linear programming formulation and an exact algorithm for a class of multidepot vehicle routing problems. This formulation co...

This paper provides integer linear programming formulations for three types of vehicle routing problems. Appropriate relaxations of these formulations lend ...

Consider a set of trips where each trip is specified a priori by a place of origin, a destination, a duration, a cost and a time interval within which the tr...

The aim of this paper is to propose a deterministic model designed for the analysis of social services policies directed toward large populations. The model...

Ce rapport a pour but de fournir une description plus précise des technologies utilisées dans l'industrie du zinc en considérant un ensemble d'activités cara...

The variational inequality problem can be formulated as a nonconvex, nondifferentiable optimization problem. We show that this formulation leads to a conver...

This paper provides an integer linear programming formulation for a class of multidepot vehicle routing problems. This formulation contains degree constrain...

Bus fleet route planning is often carried out in the following two sequential stages:<br> 1) Based on the demand, determine the trips to be carried out.<br>...

In this article, two Lagrangean relaxations for the vehicle routing problem with time windeow constraints are examined. In the first case, the scheduling co...

Recently much attention has been focused on multilevel programming, a branch of mathematical programming that can be viewed either as a generalization of min...

The deepest, or least shallow, cut ellipsoid method is a polynomial (time and space) method which finds an ellipsoid, representable by polynomial space integ...

A two country differential game mode of whaling is used for analysing a dynamic bargaining problem. At a given initial time, the two countries may either co...
