A multi-criteria decision making framework for aircraft dispatch assessment

The aircraft dispatch decision is a complex analysis based on many factors related to airworthiness regulations, aircraft health status, resource availability at current and future stop(s) and operational preferences of the operator. Within the turnaround time (TAT) a decision has to be made whether the aircraft can return to service, defects...

Component-Based Data-Driven Predictive Maintenance to Reduce Unscheduled Maintenance Events

Costs associated with unscheduled and preventive maintenance can contribute significantly to an airline's expenditure. Reliability analysis can help to identify and plan for maintenance events. Reliability analysis in industry is often limited to statistically based approaches that incorporate failure times as...

Aircraft Disposal and Recycle Cost Estimation

The present study develops a method for the sake of evaluating Disposal and Recycle (D&R) cost in view of the increasing demand in aircraft retirement. Firstly, a process model is extracted. The subordinated cost elements are also identified. Next, the cost aggregations based on the D&R process steps are discussed. Moreover, it proposes...

Automating Contextualized Maintenance Documentation

Currently, task support information in aircraft maintenance is mostly provided using paper-based solutions, which are burdensome, slow and prone to error. Aircraft maintenance documentation contains vast amounts of information irrelevant for the task at hand and even for the simplest tasks multiple documents need to be consulted. Next to these...

Measuring compliance during aircraft (Component) redeliveries at KLM engineering & maintenance

Aircraft and aircraft components are redelivered to the next operator or owner during the phase-out process. During this process the operator is required by law and contract requirements to show compliance with maintenance procedures. At KLM E&M the phase-out documentation process is under increasing scrutiny as the number of aircraft...

Air Transport and Operations. Proceedings of the Third International Air Transport and Operations Symposium 2012

Air transport must evolve if it is to optimize its value in the 21st century. The mood in the aerospace industry is positive with regard to economic recovery, but the focus in this transitional time must be on sustaining value, without losing sight of environmental and safety priorities
