Product Life Cycle Support PLCS

Product Life Cycle Support (PLCS)

• ISO/TC184/SC4
• Myrtle Beach, USA
• Feb 2002

Agenda

• What is PLCS?
• What has been achieved to date
• Current Issues for SC4
• PLCS intentions

Product 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

4
Setting 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?

Current 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

7
Lessons 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

8
Lessons 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

Activities performed (work, tasks) by people
acting on a product ( asses impact, design,
manufacture, test, repair, move etc)

Realization
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
acting on a product ( asses impact, design,

SC4 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)?

12
PLCS 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
