iVHM and the role
of digital twin
IVHM is to ensure reliability,
safety, and efficiency while also
minimizing vehicle downtime
and optimizing maintenance
scheduling. IVHM generally
makes use of sensors onboard
the vehicle with advanced
models, algorithms, and realtime
analytics to monitor the
condition of critical components
and systems.
The adoption of digital IVHM
However, this is a digital twin in its most
rudimentary form. To many, a digital twin offers
" functionality, " or the ability to virtually rerun events
that have happened on the real system and simulate
future performance. However, this requires models
based on the physics of the system to be built into the
digital twin, links to data from sensors on the real live
system, and sophisticated algorithms incorporating
artificial intelligence (AI) and machine learning (ML).
All of this can be used for integrated vehicle health
management (IVHM) decisions, such as determining
future failure, root cause analysis, and optimized
energy performance. These can also be used to make
decisions to optimize the operation of an aircraft and
may potentially extend into safety-based decisions as
well.
IVHM is a holistic methodology for monitoring,
assessing, and managing the health of complex
systems. Its use is especially prevalent within the
aerospace and automotive sectors. The primary aim of

is expected to accelerate with
the advancement of related
technologies, such as the
Internet of Things (IoT), edge
computing, big data analytics,
and cloud platforms. These
technologies enable the
seamless integration and
analysis of large-scale data,
making digital IVHM more
accessible and scalable for
various industries. This digital
revolution has also seen the use
of digital twins playing a crucial
role in the implementation of
IVHM. The digital twin provides
a holistic " virtual "
representation of the physical
asset or system that is to be
monitored. It is created by
integrating various data
sources, such as sensor
measurements, historical
records, and engineering
