ATM Performance Modelling:Challenges
SESAR performance orientation:
• Policy – qualitative performance objectives
• Objectives – measurable indicators
• Management actions – indicator trends
European ATM performance governed by SES Performance Scheme:
• Performance targeting
• Benchmarking
Needs:
• Analyse interdependencies/trade-offs between KPAs
• Characterise performance drivers
• Effective target setting and benchmarking
3SIDs 2016 - Visual Analytics and Machine Learning for Air Traffic Management Performance Modelling
Data Science:Opportunities
Data Science:
• Discover patterns and extract knowledge from data
• Variety of techniques: statistics, machine learning…
• Synonym for Business Intelligence, Data Analytics…
Opportunities:
• Increasing availability of data
• Big data technologies
• New data analysis and visualisation techniques
How can we apply these ideas to ATM performance modelling?
What is their potential for ATM performance monitoring and management?
4SIDs 2016 - Visual Analytics and Machine Learning for Air Traffic Management Performance Modelling
The INTUIT Project
Explore the potential of visual analytics, machine learning and systems
modelling to improve our understanding of the trade-offs between ATM KPAs,
identify cause-effect relationships between KPIs, and develop new decision
support tools for ATM performance monitoring and management
• Start March 2016, duration 24 months

INTUIT Approach
1. Multiscale characterisation of ATM performance data:
• Data collection and quality assessment
• Qualitative analysis of performance drivers and trade-offs
INTUIT reference datasets + set of research questions
2. Data analysis and performance modelling
• Visual analytics of performance data: exploratory data analysis
• Machine learning and statistical analysis: identification of patterns and relationships between indicators
• Models of KPI evolution explaining and/or reproducing the observed patterns and trends
ATM performance analysis techniques
3. Performance monitoring and management tools

SESAR is focused on accidentsmeasurements, whilst in SESmore on their prevention(safety management)
Safety
SES establishes «ATFM delay» as target, while SESAR focuses on throughput, which is linked
Capacity
SES targets are based on flight efficiency and SESAR addresses
fuel efficiency directly
Environment – Flight Efficiency
Partial consistency betweenDUC and Technology Cost perflight and ATCO productivity
