Distributed Aircraft Maintenance Environment (DAME)
DAME is an e-Science pilot project, demonstrating the use of the GRID to implement a distributed decision support system for deployment in maintenance applications and environments.
It is funded by the EPSRC under the UK e-Science programme, and is one of six EPSRC projects launched in the first phase of UK e-Science funding. DAME is funded for 3 years commencing Jan 2002, with a budget of £3.5 Million, supporting a research team of over 30 staff.
DAME will demonstrate how the GRID and web services (based on OGSA) can facilitate the design and development of systems for diagnosis and maintenance applications which combine geographically distributed resources and data within a decision support system.
The challenge for DAME is to consider the design of a Grid based system that can support of engine diagnostics on a global scale.
The architecture will pull together a diverse range of tools and applications, data sources and experts in a system facilitated by Globus Grid standards and Grid service middleware. Much of the middleware will be developed within the project and will contribute to the UK e-Science programme.
Data used to identify novelty
Data to be searched for
One of the core technologies within the concept demonstrator will be a neural network based diagnostic system. The QUOTE system provides real-time monitoring and fault diagnosis for aerospace jet engines.
QUOTE will be adapted so that it is available as a core web service application within the demonstrator environment, demonstrating how the GRID model can be used to exploit specific computing resources within a general maintenance framework.
The DAME project will be based upon an open web services architecture, built upon the Globus GRID models. One of the research issues to be addressed within the project is the applicability of these web service models for supporting the collaborative working environments required for maintenance decision support systems. An overview of the DAME architecture model is shown below.
The diagnostic framework developed within DAME is being demonstrated in the context of the engine maintenance problem. However, the techniques being developed will be generalised to other domains, and will be assessed for applicability in areas such as remote health applications, pharmaceuticals, and industrial monitoring systems.
An industry based Steering Group has been set up to facilitate the wider deployment and dissemination of the methods and techniques.
