Title: Product Life Cycle Support PLCS
1Product Life Cycle Support (PLCS)
- ISO/TC184/SC4
- Myrtle Beach, USA
- Feb 2002
2Agenda
- What is PLCS?
- What has been achieved to date
- Current Issues for SC4
- PLCS intentions
3Product Life Cycle Support (PLCS)Background
- A joint industry and government initiative to
accelerate development of new standards for
product support information - An international project to produce draft ISO
standards within 3 years. - PLCS will ensure support information is aligned
to the evolving product definition over the
entire life cycle - PLCS utilizes ISO 10303 STEP - the STandard for
Exchange of Product model data
4Setting the Business ContextBusiness Problem
- How to keep the data needed to operate and
maintain a product in line with the changing
product over its in-service life?

As-Is/To-Be process
6Current Position
- Business modeling and requirement capture are
complete - Data Modelling is progressing well (70 at ARM
level) - PLCS has adopted the STEP Modular Approach for
its complete scope - Clarity of intent PLCS will be part of ISO
10303 - Improved harmonization (incl. re-use of PDM
Modules) - Progressive publication option (As Application
Modules) - Will publish single AP using 150 modules (80
re-used, 70 new) - Lots of interest from major projects and from
vendors
7Lessons learned (1)
- STEP is greatly valued by its major industrial
sponsors (ISO 10303) - The Modular approach is viable and cost effective
- A framework for effective co-operation between
APs (i.e. common EXPRESS) - Progressive publication (as Application Modules)
- PDM Modules have the potential to provide a
common core for future APs, to which data from
current APs can easily map (via PDM Schema) - New STEP Module repository will greatly reduce
Module development and documentation effort
8Lessons learned (2)
- Observations
- Use of STEP (ARMAIMmappings) aids, but does not
guarantee interoperability usage guides and
test fora are essential - Modules do NOT remove requirement to for
integration within an AP a pile of bricks is
not a wall - STEP is hard to explain to business users
- Action Areas
- STEP infrastructure needs extension to exploit
EXPRESS 2 - STEP cannot yet handle the full scope of life
cycle data, as envisaged by the SC4 strategy - STEP can learn from other SC4 projects

History
States of environment windy, acidic, peacetime,

States of people available, trained to skill
level 4, occupied
Being
States of a product
Composition, structure definition
Properties
Named states operating states, fault states,
repair status
Current STEP Strengths
States of activities off/on, started, paused,
step 3 completed
Activities performed by a product
Doing
Operational behavior (functions, I/O, sequence
etc.)
Embedded support functions (diagnostics, BITE
etc).
Behaviour of support equipment (test equipment in
a facility)
Activities performed (work, tasks) by people

11SC4 issues
- Need to extend Part 41 to address Extensible
Selects (and other EXPRESS 2 features?) - Need to provide more EXPRESS 2 tools
- Need to reduce overload on product
- Need to identify, and distinguish between, life
cycle stages - Need to provide linkage from STEP to Reference
Data and Catalogues - Set theory IR
- Concepts of Class (?)
- Need to extend Part 49 to address work planning?
- Need to develop common modules for new APs to
address task, action, activity, function,
behaviour (doing)?
12PLCS Intentions
- Work with PDES, Inc to complete the PDM Modules
(quickly) as an essential foundation for the PLCS
AP - Help update Part 41 to reflect Extensible Select
- Are raising a SEDS Issue
- Can offer resource to solve this
- Are supporting AP221 in introducing the Set
Theory IR - Are working with AP233 to maximize common
modules - Common approach to product structure (start with
required product? - Common approach to defining properties, function
and behaviour - Will deliver a growing set of Application
Modules, during 2002 using the new toolset - Will publish a major new Modular AP in October
- PLCS is committed to STEP
- We need your help to further develop SC4
capabilities to address full life cycle needs
