Currently, task-specific support information in aircraft maintenance is mostly provided using paper-based solutions, which are burdensome, slow and prone to error. Next to these issues, Aircraft Maintenance Technicians (AMTs) have very limited on-site access to support information. This leads to 15-30% of handson-aircraft time being wasted on acquiring the right information or not using mainten...

In response to increased capacity and demand requirements of global air transportation predicted by 2025, the current U.S. air transportation system is being modernized by the implementation of the Next Generation Air Transportation System (NextGen). This overhaul and modernization effort links aircraft, air traffic controllers and airports through advanced satellite assisted computer networks ...

The purpose of this paper is to develop the multiobjective optimization model in order to evaluate suppliers for aircraft maintenance tasks, using goal programming. The authors have developed a two-step process. The model will firstly be used as a decision-support tool for managing demand, by using aircraft and flight schedules to evaluate and generate aircraft-maintenance requirements, includi...

We present a discrete-event simulation model for maintenance operations of a fleet of fighter aircraft in crisis situations, where the fleet operations are affected by a threat of an enemy's actions. The model describes the flight process and basic modes of periodic maintenance and failure repairs. Features that are specific to crisis situations include battle damages of the aircraft, decentral...

An optimization method for condition based maintenance (CBM) of aircraft fleet considering prognostics uncertainty is proposed. The CBM and dispatch process of aircraft fleet is analyzed first, and the alternative strategy sets for single aircraft are given. Then, the optimization problem of fleet CBM with lower maintenance cost and dispatch risk is translated to the combinatorial optimization ...

The basic purpose of aviation maintenance is to prevent the decreased levels of original aircraft airworthiness, safety and reliability design at the lowest cost, which is of great significance to the running of air transport enterprises. According to statistics, aviation maintenance accounts for approximately 20% to 30% of direct operating costs, not including indirect costs caused due to main...
