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...
