A decomposition method for global optimization, when some of the problem variables are integer, is presented. Potential solutions for a specific problem ar...

We describe the analytic center cutting plane method and its relationship to classical methods of nondifferentiable optimization and column generation. Impl...

This article describes the results of a study aimed at improving linen delivery operations in a large teaching hospital in Montreal. Improvements over the p...

We propose a common solution approach for different crew scheduling problems arising at the planning and operational levels in the airline industry. Specifi...

This paper introduces a strong valid inequality, the 2-path cut, to produce better lower bounds for the Vehicle Routing Problem with Time Windows (VRPTW). ...

This article considers a tool loading problem whose objective is to minimize the number of tool switches over time in order to process several parts on a fl...

This paper describes two variant of the Indian MARKAL model, a long-term technology oriented optimization model for energy-environment planning for India. T...

The need for an integrating framework for vehicle routing and crew scheduling problems has been apparent for some time. While several attempts have been ma...

The paper considers two cases of variational inequality problems. The first case involves an affine monotone operator over a convex set defined by a separat...

Since the work of Zwart, it is known that cycling may occur in the cone splitting algorithm proposed by Tuy in 1964 to minimize a concave function over a po...

Consider a set <i>L</i> of potential locations for <i>p</i> facilities and a set <i>U</i> of locations of given users. The <i>p</i>-median problem is to loc...

Optimal control problems for linear stochastic continuous time systems are considered, where the time domain is decomposed into a finite set of <i>N</i> dis...

<i>Extensive facilities</i> are structures that are too large to be considered as single points. In the first part of this paper we propose integer program...

Here we propose a general class of generalized linear models to describe time series of counts <i>Y</i>₁, ... ,<i>Y_n</i>. Following Ze...

In this paper, we consider the problems of robust stability and control for the class of uncertain discrete-time linear systems with Frobenius norm-bounded ...

In this paper, we first study the problems of robust quadratic mean square stability and stabilization for a class of uncertain discrete-time linear systems...

In the modeling of biological phenomena, in living organisms whether the measurements are of blood pressure, enzyme levels, biomechanical movements or heart...

Finding extremal graphs for expressions involving one or more invariants is viewed as a problem of combinatorial optimization. The recent Variable Neighborh...

Multi-commodity flow models are well known and have been widely used in the design of packet-switched networks. They have also been used as approximations ...

This paper presents a sophisticated mixed integer linear programming model developed to help the regional decision makers in the long-term planning of the s...
