Uncertainty quantification is a new paradigm in industrial
analysis and design
as it aims at taking into account the presence of numerous
uncertainties
affecting the behavior of physical systems. Dominating
uncertainties can be
either be operational (such as boundary conditions) and/or
geometrical
resulting from unknown properties, such as tip clearances of
rotating
compressor blades or from manufacturing tolerances.
Whether bringing a new product from conception into
production or operating
complex plant and production processes, commercial success
rests on careful
management and control of risk in the face of many
interacting uncertainties.
For example a new aircraft or aero-engine must be designed
and engineered
within a given time frame and budget to meet a given set of
performance
requirements, and then manufactured at unit cost and rates
that meet an
overall business plan. Todays fiercely competitive market
and increasingly
stringent regulatory environment is such that there is very
little margin of
error. Failure to appreciate, understand and appropriately
manage risks
inevitably results in severe financial penalties, and even
irrevocable damage to
reputation.
Historically, chief engineers and project managers have
estimated and
managed risk using mostly human judgment founded upon years of
experience and heritage. As the 21st century begins to
unfold, the design and
engineering of products as well as the control of plant and
process are
increasingly relying on computer models and simulation. This
era of virtual
design and engineering opens the opportunity to deal with
uncertainty in a
systematic formal way by which sensitivities to various
uncertainties can be
quantified and understood, and designs and processes
optimized so as to be
robust against such uncertainties. Human judgment will
always play an
important role, but leading companies in many fields of
engineering are
increasingly aware of these possibilities and uncertainty
quantification is
beginning to feature strongly in their strategic
aspirations. Thus this is a very
opportune moment to introduce a two- day awareness course on
this
emerging topic. The aim is to share the aspirations and
requirements of
leading companies in the fields of aerospace, energy,
transport and chemical
process; review emerging methods and techniques and how
these are being
deployed; and define the current state-of-the-art and map
out-near term
future possibilities.
Uncertainty quantification has become a critical feature of
a computational
methodologies which will be utilized within an engineering
design process.
There has been considerable progress in this field at both
the national and
international level. The purpose of this two-day hort course
is to bring some
the most promising approaches and developments in this field
to the
attention of researchers and engineers from academia,
industry and research
laboratories.
A recent development has been a short course arranged by Dr.
Charles Hirsch
of Belgium, who has organized an ERCOFTAC short course,
Uncertaintly
Management and Quantification in Industrial Analysis and
Design, which was
delivered in Munich, Germany on March 3-4, 2011. This course
is being
brought to the US research community by the National
Institute of Aerospace.
