We compare the effectiveness and efficiency of alternative operational dispatching policies that are integrated into the design phase of a circular material ...

This paper presents a model for identifying general goals of anonymous consumers visiting a retail website. When visiting a transactional website, consumers ...

This paper presents an overview of the column generation method developed at the GERAD research center in Montr'eal for solving large scale vehicle routing ...

Necessary and sufficient conditions are provided for existence of a simple graph <i>G</i>, and for a simple and connected graph <i>G'</i> with given numbers ...

We consider an inequality of the type <img src="/cgi-bin/mimetex.cgi?A\cdot x\le B\cdot x"> over the idempotent semifield <img src="/cgi-bin/mimetex.cgi?R_{...

Question retrieval systems, unlike question answering systems, exploit the knowledge contained in previously answered questions to answer new ones by returni...

Based upon a robust optimization technique, Variable Neighborhood Search (VNS), we use simulation to find rules for identifying the correct Minkowski paramet...

The Improved Primal Simplex algorithm IPS [8] is a dynamic constraint reduction method particularly effective on degenerate linear programs. It is able to ac...

Vector periodic autoregressive time series models (PVAR) form an important class of time series for modeling data derived from climatology, hydrology, econom...

In this paper, we propose a Partial Differential Equation formulation for the value of an option when the underlying asset's price is described by a discrete...

There has been a wide interest to extend univariate and multivariate nonparametric procedures to clustered and hierarchical data. Traditionally, parametric m...

We present a procedure for self calibration of a pinhole camera subject to radial distortion. Radial distortion parameters are estimated using a nonlinear le...

The Protected Working Capacity Envelope (PWCE) concept was proposed by Grover (2004) in order to simplify network and operation management in survivable WDM ...

We review the basic principles of Quasi-Monte Carlo (QMC) methods, the randomizations that turn them into variance-reduction techniques, the integration erro...

Top-tier customers - that is, those 20% of customers that typically bring in 80% of all profits - are extremely valuable to companies. In the many instances ...

We consider filter design of a linear system with parameter uncertainty. In contrast to the robust Kalman filter which focuses on a worst case analysis, we p...

Frequency hopping is a feature in GSM (Global System for Mobile Communications) cellular systems in which a frequency carrying the communication rapidly chan...

Staffing and scheduling optimization in large multiskill call centers is time-consuming, mainly because it requires lengthy simulations to evaluate performan...

We consider a maritime inventory routing problem in the liquefied natural gas (LNG) business. Here, an actor is responsible for the routing of the fleet of s...

This paper addresses the split delivery vehicle routing problem with time windows (SDVRPTW) that consists of determining least-cost vehicle routes to service...
