Product Life Cycle Support (PLCS) ISO 10303-239
• A joint industry and government initiative to
accelerate development of new standards for
product support information
• An international project to produce an
approved ISO standard within 4 years
• Commenced November 1999
• PLCS, Inc. closed down late 2004
• Standard published by ISO in 2005
• Edition 2 published in 2012
• PLCS will ensure support information is
aligned to the evolving product definition over
the entire life cycle
• PLCS extends ISO 10303 STEP - the STandard
for Exchange of Product model data

• Like DEXlib but driven from SysML models • PLCS PSM
• Starting point was translation into SysML from • Decided to create a single XML schema
Express • Contrast with one per DEX
• Some model revision to make implementation • Works with current XML tools
easier
• Much smaller file sizes
• Initial harmonization with AP242 performed
• Greater use of encapsulation
• Support for DEX definition using SysML with
computer sensible mappings described via
parametric diagrams
• Tools ensure conformance to the underlying
model
• More help and background information
• Snap shot of PLCSlib published as the OASIS

Business cases
Why use PLCS now?
2018 © Eurostep GroupThere are many potential business cases for using PLCS
• Standard information interfaces for contracting
• Maintaining an Assured Product and Support Information set
• Information integration/linking across disciplines/areas/tools
• Digital Thread (including Digital Twins)
• Collaboration Hub core model (Eurostep)
2018 © Eurostep GroupStandard information interfaces for contracting
• The problem scenario: • The objective
• Defence systems come with their own IT • Suppliers use an information delivery
mechanism defined on the basis of a standard
• Data needed for operations is locked into that
IT • All suppliers of equivalent systems are treated
• And may never be available for Defence organization use the same and subject to the same contracted
requirements
• Each system supplier has their own approach
• Data delivered from suppliers can be imported
• Each supplier contract is unique and there is via a single mechanism
little or no commonality between suppliers
• No system specific IT is needed
• The same mechanisms can be used to supply
data from the Defence Organization to its
suppliers
This is the approach being taken by Sweden’s FMV and France’s DGA, using PLCS DEXs to contract.
It has also been used between Norway’s NDLO and BAE Systems Hagglunds.

2018 © Eurostep GroupWhat is the Digital Thread
• The digital thread refers to the communication framework that allows
a connected data flow and integrated view of the asset’s data
throughout its lifecycle across traditionally siloed functional
perspectives.
• The digital twin refers to a digital model of a particular asset that
includes design specifications and engineering models describing its
geometry, materials, components and behavior. More important, it also
includes the as-built and operational data unique to the specific
physical asset that it represents.
• For example, for an aircraft, the digital twin would be identified to the physical product unit
identifier which is referred to as the tail number. The data in the digital twin of an aircraft
includes things like specific geometry extracted from aircraft 3D models, aerodynamic
models, engineering changes cut in during the production cycle, material properties,
inspection, operation and maintenance data, aerodynamic models, and any deviations from
the original design specifications approved due to issues and work-arounds on the specific
product unit.

• Distinguish between designs and actuals (individuals).
• Different BOM views (such as as-designed, as-manufactured and as-
maintained) of a product, including the actuals, and link/trace between them.
• Different breakdown views (such as physical and functional breakdowns) of a
product and link between them and to different BOM views.
• Different properties and record their values over time or against different
views.
• Requirements, their allocation, tracing, Verification and Validation.
• Recording of processes and other actions applied to the product (or done by
the product).
• Handling subsidiary products such as tools and equipment and their use and
properties.
• Associated documents and other information, such as CAD and simulation
models, related to the product and any subsidiary products.

and then questions!
2018 © Eurostep GroupConclusions
• The core data model within PLCS has stood the test of time and been
successfully applied beyond its original domain
• The need for a standard like PLCS is becoming clearer as the push for
the digital thread grows
• PLCS provides the life-cycle view that many existing standards lack
• And can be used with alongside those standards to add history capabilities
