Simulation approach for aircraft spare engines & engine parts planning
Authors: Jose Ramirez-Hernandez, Steven Oakley, Mei Zhang, Alejandro Scalise
Abstract
We present the application of a simulation approach utilized for planning the required ownership levels of aircraft spare engines and parts in American Airlines. Such planning is essential to efficiently support both flying and engine maintenance operations. As such, this problem is very important from a financial and operational perspective given the high cost and criticality of these assets. Our models can be utilized in single and multi-location settings and are utilized to estimate the minimum ownership requirements to satisfy a given service level. In addition, our models can provide other important operational information such as out of service related metrics. To illustrate the utilization and versatility of the models, three case studies with actual industry data are presented. Results from these case studies demonstrate the value of the information generated by our models which facilitates the ownership planning and can also be used to support other related decision processes.
