Optimize PIS Maintenance
“We want to design an information-infrastructure, capable of correlating the available status information, in order to perform cost-effective
maintenance”
Current Work

Much Information Available
How ?
1. Perform measurements per componentOn demandScheduled
2. Store measurements3. Correlate the information4. Draw conclusions
Advantages !
RobustEfficient maintenanceLess expensive maintenancePrediction of faults and failuresSelf-descriptive….
}Use of Semantic Web’s First-Order Logic Ontology

From Idea to Architecture
Functional Building blocks
Obtain status-information from components
Analyze communication between components
Impose consequences
Provide feedback to the Users
Easily install now model of the system

Introduction to ontology
RDF (Resource Description Framework)Basic expressiveness
OWL (Ontology Web Language)built on top of RDFLite: classification hierarchy and constraint featuresDL (Description Logic): maximum expressiveness without losing computational completeness and decidabilityFull: maximum expressiveness and syntactic freedom with no computational guarantees

Conclusions
Currently:
Maintenance = straightforward BUT inefficientMaintenance = f(MTBF)
failure
Proposed maintenance application
Maintenance optimized per componentMaintenance tool for visualisation
Maintenance = simple AND more efficientMaintenance = f(MTBF, cost)

Conclusions
Value for MoneyOperator/Owner
+ Financially interesting+ Improved robustness
Maintainer+ Easier maintenance+ Improved planning
Passengers+ Greater uptime for components and systems+ Improved and up-to-date information
Ontology+ dynamic, reasoning, self-descriptive,…- complex and (currently) not yet performant
