In this paper we analyze the problem of finding the trading area for a facility on a linear market. Given the objective of maximizing profit, we first build...

The aim of this note is to show that the algorithm recently proposed by J. Bard (1983) is not guaranteed to converge to the desired solution of a Linear Two-...

This paper examines a class of asymmetrical multi-depot vehicle routing problems and location-routing problems, under capacity or maximum cost restrictions. ...

This research deals with the Planning of Operation on a two-machine cell consisting of: a) a (NC) turret-mounted multi-tool punch, b) a (NC) shear. The cell...

In this paper, an extension of the classical scheduling problem is considered. It is assumed that tasks are processed on parallel processors, available at d...

Recently we have witnessed the development of a fast growing body of research focused on vehicle routing and scheduling problem structures with time window c...

Location-routing problems involve simultaneously locating a number of facilities among candidate sites and establishing delivery routes to a set of users in ...

This paper considers a vehicle routing problem with full loads and time limit constraints. This problem can be formulated as an asymmetrical travelling sale...

The oil refining industry is an important part of the Canadian energy supply system which has to adapt itself to the new energy demand patterns emerging from...

This report presents the structure and the possible uses of a long range system analysis tool which models the evolution of the energy needs of the Canadian ...

This report deals with the long range modelling of energy needs in the cement industry. Starting from the analysis already performed for the Québec energy s...

This report presents the structure and the possible uses of a long range system analysis tool which models the evolution of the energy needs of the Canadian ...

Hydraulic turbine runners are used in electricity generation. These consist of a cylinder around which are welded, at regular spacings, a number of blades w...

Existence theorems for Pareto optimal solutions of infinite horizon optimal control problems, with cost criteria described by a vector valued improper integr...

In this paper the authors describe a heuristic principle for the solution of an important class of problems. Using real-world examples, it is then shown how...

Post box collection constitutes a complex and costly operation in most postal services. The authors recently undertook a study aimed at improving this opera...

A qualitative model is proposed by the economic analysis of the power exchange between two utilities. The model combines an infinite horizon optimal control...

This article examines a constrained shortest path problem which occurs in the design by column generation of vehicle routes constructed to satisfy a set of t...

A process planning problem typically encountered in flexible manufacturing systems treating laminated material (e.g. metal sheets) is modelled and solved. I...
