@MOST-G SO4A Service Oriented System Architectures for Fleet Operation

In the changing aviation market, the operation of a modern Aircraft fleet sets high requirements, not only towards the aircraft itself but also to the operation infrastructure. Fleet operation is the more efficient the shorter an aircraft turn-around time on the ground is, and the longer the operational hours until the next maintenance. Thus it is inevitable to reduce the maintenance and repair effort by efficient procedures, in order to substantially increase the profitability of aircraft operation.

The project @MOST-G Service Oriented System Architectures for Fleet Operation develops new solutions for the maintenance and repair to increase aircraft operation efficiency and create new maintenance support facilities. For this purpose, aircraft operations as a whole system should be considered. A system architecture is required, which considers the efficiency of an end-to-end maintenance concept of an airline. In this process, service oriented architectures (SOA) can be applied. SOA permits high flexibility and long-term re-use. In this way, new services can be integrated in aircraft and ground operations and existing services can be combined to implement new functions.

Starting from todays architectures in form of a validated architecture model, an optimized service oriented system architecture with corresponding services, or service combinations, will be designed and implemented. Individual services can be located on board of the aircraft as well as on the ground. The design also covers an appropriate infrastructure with common basic aircraft and ground services, an uniform service directory as well as the definition of availability and security.

Due to the continuously increasing complexity od aircraft operations, it is today not longer possible to accomplish the system design only by a functional breakdown into single aircraft elements and to optimize the design of the individual components. Rather synergies and and correlation of actions and effects should be considered. Therefore, the models will be made investigated  by the help of a simulator. Then, coupling effects and distinct architecture variants can be analyzed already during the system design phase.

The project is funded by the LuFo programme of BMWi.
