We propose a 0-1 column generation model for the problem of channel assignment in a cellular network, with the objective of minimizing the unsatisfied chann...

Central limit theorems are obtained for the ``perturbation analysis Robbins-Monro single run'' (PARMSR) optimization algorithm, with updates either after ev...

In recent years, there have been several important algorithmic developments for the traveling salesman problem and the vehicle routing problem. These incl...

This study concerns a generic model-free stochastic optimization problem requiring the minimization of a risk function defined on a given bounded domain in ...

One of the many problems faced by rail transportation companies is to optimize the utilization of the available stock of locomotives and cars. In this paper...

The aim of this paper is to present a survey of recent optimization models for the most commonly studied rail transportation problems. For each group of pro...

In the last 15 years, considerable efforts have been placed on integrating product and process design. This integration can improve product quality, reduce...

An FMS environment requires a flexible and adaptable material handling system. Automated guided vehicles (AGV) provide such a system. One of the component...

The paper is concerned with conflict and coordination in a two-member channel of distribution. We propose a differential game model that includes carry-ove...

If it is assumed that the final product of bromination of C₆₀ will obey two rules, (i) that no two <i>sp</i>³ carbons may be adjacent,...

A module over a principal ideal domain splits into a direct sum of a free module and a torsion module. This decomposition does not hold in general for semim...

This paper describes a decision support system based on a sophisticated mixed integer linear programming model, EUGENE, developed to help the regional decis...

We are interested here in the reachability and controllability problems for DEDS in the max-algebra. We show that these problems lead to an eigenvector prob...

We analyze the multiple cut generation scheme in the analytic center cutting plane method. We propose an optimal primal and dual updating direction when th...

We consider the problem of minimizing makespan in two-machine no-wait flowshops with multiple products requiring lot streaming. A "product" (or lot) consist...

For many years banks designed their promotional efforts to aim at the broadest possible markets in hopes of recruiting new clients. Recently, competitive me...

We consider an ATM switch model, in which each of <i>N</i> sources is a Markov modulated rate process. We look at some approximations that have been propos...

Since the beginning of 90's, <i>risk management</i> has become an important topic of research for both the academic and financial institutions. Progress in ...

Column generation is often used to solve large scale optimization problems, and much research has been devoted to improve the convergence of the solution pr...

This paper studies the informational content of elective teams in a dynamic agency framework with adverse selection. Two agents with different employment hi...
