Market drivers in the civil aviation indus-
try are pressing for a leaner service supply
chain. Increased demand, fuel prices, and
market competition is causing airlines to de-
velop and expand their internal capabilities
to reduce costs. This means airline mainte-
nance companies, which currently account
for nearly 60 percent of market share, are
set to increase collaboration with indepen-
dent service providers and original equip-
ment providers. To further reduce costs and
accommodate the increased demand for air
travel, suppliers are globally sourced, com-
plicating the service optimization problem.
The sector also aims to reduce no-fault-
found investigations, which cost the
industry $300 million per year.

maintenance is now a common aim among
many leading service providers.

Another
factor that demands changes in the current
structure is the increase of ly-by-the-hour
contracts instead of total ownership, bind-
ing manufacturers more tightly to the
delivery of intelligent services, where intel-
ligence is measured as an output in terms of
reduced service costs and increased compo-
nent life in service.
This search for intelligent services had led
us to develop the self-serving asset. The self-
serving asset is an evolution of the intelligent
product, deined as the coupling of a product
and an information-based representation that
• possesses a unique identi ication,
• can communicate effectively with its
environment,
• can retain or store data about itself,
• deploys a language to display its features
and requirements, and
• can participate in or make decisions rel-
evant to its own destiny.

We believe that a product is an asset to
its manufacturers until the point of sale. At
that point, the product becomes an asset
to its new owner. However, if it continues
T
he aerospace service supply chain deals with the procurement of parts,
software, and human resources to update, service, and maintain prod-
ucts throughout their service life. This supply chain is immensely complex as
a result of ad hoc, unpredictable service requests; the frequent pull of various
