The tail assignment problem is a critical part of the airline planning process that assigns specific aircraft to sequences of flights, called lines-of-flight, to satisfy operational constraints. The aim of this paper is to develop an operationally flexible method, based upon the one-day routes business model, to compute tail assignments that satisfy short-range—within the next three days—aircra...

This paper describes a safety information management system designed to capture maintenance factors that contribute to aircraft mishaps. The Human Factors Analysis and Classification System-Maintenance Extension taxonomy (HFACS-ME), an effective framework for classifying and analyzing the presence of maintenance errors that lead to mishaps, incidents, and personal injuries, is the theoretical f...

This report details the second phase of the Office of Aviation Medicine research program on Human Factors in Aviation Maintenance. This on-going research program enhances human performance in the aviation maintenance system to ensure continuing flight safety and operational efficiency. The research program, as reported in the Phase I report (Shepherd, Johnson, Drury, Taylor, & Berninger, 1991) ...

The operations of aircraft fleets typically result in large volumes of data collected during the execution of various operational and support processes. This paper reports on an Army-sponsored study conducted to research the applicability of data mining for processing such data. The study focused on three aspects: (1) understanding the aviation operations, maintenance environment, and data coll...

Flight and Maintenance Planning (FMP) of mission aircraft addresses the question of 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 objective is to achieve maximum fleet availability of the unit over a given planning horizon, while also satisfying certain flight and maintenance r...

This paper is about a computer application for planning maintenance of aircraft fleet in what regards allocation skilled technicians. The formalization this mathematical programming problem written as minimizing one. decision variables are the data number available technicians, working hours needed to accomplish maintenance, costs due daily operation facilities, and downtime. Although, non-line...

This work is motivated by a particular scheduling problem that is faced by logistics centers that perform aircraft maintenance and modification. Here we concentrate on a single facility (hangar) which is equipped with several work stations (bays). Specifically, a number of jobs have already been scheduled for processing at the facility; the starting times, durations, and work station assignment...
