SCALES: Resilience potential and early warnings for Air Traffic Management in case of system degradation through Enterprise Architecture.
SCALES is a SESAR WP-E project which started in Autumn 2013 and it will end in Spring 2016. This project addresses the following research question:
- What added value can the combination Enterprise Architecture (EA) with Resilience Engineering (RE) bring to measure the resilience potential of the ATM system?
Its main objective is to identify indicators as early warnings signs and as measures to quantify the potential for the resilience of the ATM system. The purpose of the indicators is to provide actionable information to keep the system under control in case of small and catastrophic perturbations demonstrating practical benefits in specific real ATM cases. The central goal of SCALES is to link Resilience Engineering and Enterprise Architecture principles into a framework (the "SCALES Framework") that enables a context driven analysis of resilience. Enterprise architecture will offer the opportunity to model system of systems and to consider the system from different viewpoints (functional, communication, information and process view). For each viewpoint SCALES will identify appropriate resilience related indicators. These will be measured and monitored during system in operation, providing information about system ability to adapt to perturbations and maintain its functionality in specific cases. SCALES is oriented both to the industry and also to the research community. For the former, it monitors the capacity to adapt and cope with disturbances and looks for proactive indicators and early warnings considering technical, operational and organizational aspects. For the latter, it provides a systemic approach and associated tool to represent resilience and its related indicators
Project objectives and achieved results
The project achieved the following innovation and research objectives:
- Innovate the state-of-the art in RE with a SCALES framework that combines principles from Enterprise Architecture EA with principles from RE.
- Define and develop SCALES framework based on EA tailored to the ATM, integrated with a questionnaire addressing resilience abilities (monitor, anticipate, respond and learn) and properties (buffering capacity, flexibility and cross-scale interactions).
- Allow validation and monitoring of resilience in realistic case studies representing highly relevant technical and operational functions and typical for future ATM infrastructure.
- Promote and contribute to open European ATM enterprise architectures and resilience analyses showing how technical, social and regulatory aspects cannot be considered in isolation.
- Disseminate the results effectively within SESAR and the scientific community, and promote their future application through knowledge transfer towards industry and service providers. The SCALES framework will be delivered as a web tool with open access to all potential users.
Main result have been SCALES framework web tool and guidelines showing how resilience related indicators can be identified using different viewpoints of a system. Additional results:
- Advances in theory: by combining EA and RE to provide more efficient and more confidence of the representativeness of the indicators.
- Advances on practical representations of resilience analysis including set of questions: Currently resilience analysis lack of the use of advanced tools that support RE.
- Promote and facilitate utilization of enterprise architecture and resilience: Verification and validation in realistic cases representing highly relevant technical and operational functions and typical for future ATM infrastructure
