Abstract:
Cost-effectiveness and accuracy are two basic criteria
for good maintenance. Reducing maintenance costs can increase
net profit, while accurate maintenance actions can sustain
continuous and reliable operation of equipment. As instruments
and information systems tend to become cheaper and more
reliable, condition-based maintenance has become an important
tool for running a plant or a factory. This paper presents a novel
condition-based maintenance framework that uses reliabilitycentered
maintenance to save money and employs the data fusion
strategy for improving condition monitoring, health assessment,
and prognostics. This framework can help obtain optimal
maintenance performance with good generality.
