Holistic maintenance information with multi-layers of contractors

Sammanfattning:
In Sweden, the railway system is deregulated, with several
layers of operators and contractors. By defining maintenance,
its objectives and responsibilities, an operation can
become cost effective and problem-free. To make this work
in a system with many stakeholders, good information flow
is crucial. With a holistic computerized information system,
each stakeholder can assess maintenance effectiveness, including
availability, reliability and maintainability. For this
knowledge to be available, the condition of the railway vehicle
assets has to be monitored, either manually and/or with
wayside detection equipment. If work orders are automatically
generated, human factors (i.e., inconsistency) can be
reduced. The article uses a vehicle wheel axle as a case
study. The maintenance cost for this asset generally represents
a large portion of the total maintenance budget; for
example, re-tyring a wheel costs about ten times more than
re-profiling.
