Motivation
• Data heterogeneity– Customers: Extensive non-standardised data– Gaps, errors and uncertainties related to the data– Inconsistent data formats
• Differences in vocabulary: – Data channel names – Models vs. numerical methods– Variables (e.g. inputs, outputs) vs. parameters (model, numerical)
• The size of the evolving data, the heterogeneities and the inconsistencies inflict a cost on robust and systematic model development and application
• Ontology, a key part of the overall solution: formal, explicit specification of a shared conceptualisation

Engine operating window
4.4l Turbocharged Aftercooled (TA) Tier 4 capable IC engine
• Background & objective– CAT 4.4 IC engine used in multiple machines/applications: agriculture,
construction, cranes, loaders, etc. – Engines designed to meet stringent emissions regulations
– To develop and apply an integrated workflow combining physico-chemical and statistical models to augment the measurements data
– Data heterogeneity and evolution are the main drivers for standardisation

engineML
• Consistent format
• point data (e.g. rpm, CO, ul) • time resolved data (p-CA)• Apparatus (production engine, research engine)• errors• data type (consistent units)• raw or processed
• XML code selected
machine and human readable tree structure validated against schema
• Easily accessible database
read by model code data stored consistently old data never forgotten

Friction
• Statistical/data-driven analysis to produce a hierarchy of models
• Compare the performance of all models as a function of:• Choice of the objective function• Training, verification and
validation methodologies
• Final recommendation – model ranking based on technical criteria such as error measures and CPU expense.
