This paper deals with an infinite-horizon discrete-event dynamic programming model with discounting, and with Borel state and action spaces. Instead of the ...

In the analysis of discrete event systems, we need to consider sequences and/or matrices of elements in a given numerical set <i>D</i> (&#x2115;, Z, Q or &#x...

The urban transit crew scheduling problem arises in mass transit corporations who have to create minimal cost bus driver schedule respecting both the collect...

This paper is concerned with the decisions (output decisions and associated sell-or-process-further decisions) that arise with joint products when the techno...

A model is presented for looking at the main characteristics of long term gas contracts. The problem is formulated as a dynamic stochastic multimarket model...

This paper addresses the problem of existence and computation of cooperative equilibria of discounted stochastic sequential games. The proposed approach con...

Energy problems began a few years ago to receive proper treatment, but they are still most of the time dealt with from the supply side. The present research...

In this paper, I give a counterexample to the closedness property of the set of possible current production vectors <i>Y_f</i> which is used by J....

Old and new algorithms for the Maximum Satisfiability problem are studied. We first summarize the different heuristics previously proposed, i.e. the approxi...

This paper deals with a class of continuous time discounted models representing an incremental incentive scheme whereby a firm receives a premium if its curr...

This paper deals with a class of discounted sequential games which admit of analysis through a contracting operator approach à la Denardo. These games appea...

La justification de l'investissement en automatisation flexible pose un problème d'information et de hasard moral. La grande difficulté est la quantificatio...

This paper presents mathematical formulations for some vehicle routing and scheduling problems with time window constraints and the optimal solution approach...

This paper deals with the construction of cooperative equilibria for stochastic dynamic games, where the players cannot observe the actions of their opponent...

One considers a class of systems described by a set of state equations indexed over a finite set E. A random jump process with value in E represents the per...

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-...

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...

Nous présentons un aperçu des principales idées permettant la formulation du phénomène de négociation collective dans le langage de la théorie des jeux. Apr...

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...

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...

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

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

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

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...
