In this paper we establish a theoretical framework for a class of production and maintenance planning problems. Results obtained in this paper include local...

This paper describes strip sequencing models for large scale traveling salesman problems arising in flexible manufacturing operations in two or three discre...

Consider a set of logical sentences together with probabilities that they are true. These probabilities must satisfy certain conditions for this system to b...

The product positioning problem consists in choosing the attributes of a new product in such a way as to maximize its market share, i.e., to attract a maxi...

Lipschitz optimization solves global optimization problems in which the objective function and constraint left-hand sides may be given by oracles (or explic...

In this paper we explore a new branching strategy for branch-and-bound approaches based on column generation for the vehicle routing problems with time wind...

Several technologies and renewable energy forms are evaluated using the global energy model MARKAL. This report describes some advantages of such an approa...

This paper deals with a class of dynamic discrete time open-loop games played over an infinite time horizon. The equilibrium concept is defined in the sense...

This technical report deals with the moments of cumulative processes. More specifically, we shall evaluate the expectation of a product of triple summation ...

In this paper we analyze the efficiency of a given robot movement schedule for the case of a flowshop robotic production cell with <i>m</i> different machin...

Much work has been devoted to the problem of finding maximum likelihood estimators for the three-parameter Weibull distribution. This problem has not been c...

In this paper we analyze some properties of the discrete linear bilevel program for different discretizations of the set of variables. We study the geometry...

Multi-commodity flow models are well known and have been widely used in the design of packet-switched networks. Flow models have also been proposed for the ...

This paper addresses, from a mathematical programming point of view, the problem that consists in determining an hyperplane that separates, as well as possi...

It is well known that several combinatorial optimization problems can be nicely and readily modeled as an appropriate quadratic 0-1 function to be optimized...

The Edmonds Matching Algorithm, which leads easily to finding a Kekulé structure in a chemical graph, is recalled. An extension is made to the case where on...

In 1990, Kh. Al-Khnaifes, P. John and the author described some simple algorithms for calculating certain structural parameters (the number of Kekulé patter...

The objective of this paper is to study optimal pricing strategies in a duopoly, under an asymmetric information structure, where the appropriate solution c...

Methods of concave minimization and reverse convex programming are treated in the general framework of d.c. optimization. The presentation is self-contained...

Dans un réseau distribué d'ordinateurs, un fichier est souvent conservé sur un ordinateur particulier, appelé le serveur du fichier. Nous parlons d'informa...
