Optimization Model of Aircraft Components Maintenance Repairs

Abstract

Maintenance Repair And Overhaul ( MRO ) must efficiently perform the aircraft component maintenance and repair in order to ensure the aircraft is safe and on time for flight. The scheduling of resources for maintenance of aircrafts components is typically performed based on staff experience using some business rules. This process is not only time-consuming but often ineffective leading to unnecessary delays in handling over the components to the customers, resulting in increasing costs and decreasing customers’ satisfactions. The aim of this project is to develop optimization models for the efficient allocation and planning of resources for aircraft components maintenance. Manpower and Inventory are the most important factor in production planning, as it can significantly increase the productivity of a workshop. This report concentrates on a job-shop problem which arises at workshops of typical MRO service providers. An MRO does not only need to minimize the turn around time and maximize the plant utilization, it also needs to maximize the service and protection level of its stock. Hence, it has several objective functions which usually contradict each other. This report presents the Linear Programming algorithm which helps to find an optimal job allocation and using AHP decision analysis method to determine the spare part control policy.
