We present a new two-commodity flow formulation for the traveling salesman problem. Each commodity corresponds to a resource that is either distributed or p...

We consider a differential game model to investigate the effects of price subsidy over time on the rate of diffusion of a new technology. We assume that the...

In this paper, the expected distance between two uniformly distributed random points in a rectangle or in a rectangular parallelepiped is computed under thr...

Examination scheduling is a problem in virtually every high school, college and university. The basic challenge is to schedule examinations over a limited ...

Layout planning is an appropriate area in which to apply optimization models. A method is proposed here for evaluating general layouts (block layouts) when ...

This paper deals with the implementation of the interior point cutting plane algorithm of Goffin-Haurie-Vial, with a special application to the solution of ...

The Airline Crew Scheduling Problem can be defined as the problem of finding a set of feasible rotations so that the total cost is minimum and all the fligh...

A notion of Nash equilibrium, called event-adapted equilibrium, is defined for non-cooperative, multi-stage games where uncertainty is gradually resolved. ...

In many cities around the world, public transportation services are requested to provide adapted transportation for handicapped persons and people with rest...

L'objectif de cet article est d'analyser les facteurs de succès et d'échec de nouveaux produits de consommation et industriels. Les résultats des analyses d...

La génération d'implantation est un domaine privilégié pour l'application des modèles d'optimisation. Il est proposé, ici, une méthode d'évaluation d'implan...

Layout planning is an appropriate area in which to apply optimization models. A method is proposed here for evaluating general layouts (block layouts) when ...

This paper presents a stochastic dynamic cooperative game model of power exchange between interconnected utilities. The model is used for the qualitative a...

We consider a generalization of PERT where task durations are variable and the cost of each task is a convex function of its duration. Moreover, each preced...

The vehicle routing problem with time windows (VRPTW) is a generalization of the vehicle routing problem where the service of a customer can begin within th...

In this paper, the problem of optimally locating the numbers around a dart board is investigated. The objective considered is risk maximization. Under diffe...

This paper considers a flexible manufacturing system for several products, each requiring a number of sequential non-preemptive tasks, some of which may be...

The development of truck dispatching systems has during recent years taken two directions. One has been systems using mathematical optimization and powerfu...

In this paper we develop a stochastic, dynamic network equilibrium model of airline passenger transportation. The model explicitly incorporates the behavior...

Because of the transmission of disease producing parasites to man and animals and the nuisance caused by bites from adult black flies, they are the object o...
