An optimization approach to aircraft dispatching strategy with maintenance cost â€“ A case study

Bazargan, Massoud - In: Journal of Air Transport Management 42 (2015) C, pp. 10-14

This paper presents an optimization approach to identify aircraft dispatching strategy at a flight training school. The strategy adopted by the school was to dispatch the aircraft which is closest to its scheduled maintenance. This strategy was examined and compared with other potential...

An exact solution algorithm for maximizing the fleet availability of a unit of aircraft subject to flight and maintenance requirements

Gavranis, Andreas; Kozanidis, George - In: European Journal of Operational Research 242 (2015) 2, pp. 631-643

We address the Flight and Maintenance Planning (FMP) problem, i.e., the problem of deciding which available aircraft to fly and for how long, and which grounded aircraft to perform maintenance operations on in a group of aircraft that comprise a unit. The aim is to maximize the unit fleet...

Solving the Aircraft Landing Problem with time discretization approach

Faye, Alain - In: European Journal of Operational Research 242 (2015) 3, pp. 1028-1038

This paper studies the multiple runway Aircraft Landing Problem. The aim is to schedule arriving aircraft to available runways at the airport. Landing times lie within predefined time windows and safety separation constraints between two successive landings must be satisfied. We propose a new...

Consolidating home meal delivery with limited operational disruption

Hewitt, Mike; Nowak, Maciek; Gala, Leo - In: European Journal of Operational Research 243 (2015) 1, pp. 281-291

Non-profit organizations like the Meals On Wheels (MOW) association of America prepare and deliver meals, typically daily, to approximately one million homebound individuals in the United States alone. However, many MOW agencies are facing a steadily increasing number of clients requesting meal...

Two-phase branch-and-cut for the mixed capacitated general routing problem

Irnich, Stefan; Laganà, Demetrio; Schlebusch, Claudia; … - In: European Journal of Operational Research 243 (2015) 1, pp. 17-29

The Mixed Capacitated General Routing Problem (MCGRP) is defined over a mixed graph, for which some vertices must be visited and some links must be traversed at least once. The problem consists of determining a set of least-cost vehicle routes that satisfy this requirement and respect the...

Computationally efficient MIP formulation and algorithms for European day-ahead electricity market auctions

Madani, Mehdi; Van Vyve, Mathieu - In: European Journal of Operational Research 242 (2015) 2, pp. 580-593

We consider the optimization problem implementing current market rules for European day-ahead electricity markets. We propose improved algorithmic approaches for that problem. First, a new MIP formulation is presented which avoids the use of complementarity constraints to express market...

Reconstruction algorithm for unknown cavities via Feynman–Kac type formula

Kawakami, Hajime - In: Computational Optimization and Applications 61 (2015) 1, pp. 101-133

<Para ID="Par1">In this paper, we consider an inverse problem of identifying one or more unknown cavities in a heat conductor. We propose an algorithm for reconstructing the position and shape of the unknown cavities using the measured surface temperature of the heat conductor. The heat conductor is discretized...</para>
