3 Strategies in Re-purposing Graphics for Intelligent Delivery Business issues Standards, goodness, and style Delivering efficiency to the customer Internal efficiencies Engineering interfaces Summary

4 Strategies in Re-purposing Graphics for Intelligent Delivery Business issues Standards, goodness, and style Delivering efficiency to the customer Internal efficiencies Engineering interfaces Summary

5 Aviation Industry Paradoxes Aircraft need support over 30 years –the older the aircraft the more customers and configurations to support Myriad of publications systems and formats –the older the system the more expensive it is to migrate Engineering data is authority for revisions –The older the engineering system the greater the disconnect to publications Modern aircraft are increasingly complex –The experience age of technicians is declining Aircraft grounded are huge cost burdens –Customers require ever more efficient information retrieval

6 IETM stagnation dynamic text - static graphics Graphics are created, stored and presented as static visuals Usability of manuals have stagnated (interactivity is text based) No links available from manuals to additional data on the web Customers print wiring manuals from electronic version to be usable No interfaces from IPC to parts ordering 35% increase in trouble shooting efficiency via interactive documents not achievable without dynamic graphics

7 What is a Technical Illustration? It is not: strictly engineering data art for arts sake It is: a communicator of technical information the most efficient means of passing on spatial information An intelligent graphic is also: a navigation tool the most efficient means of passing on spatial and textual information

8 Technological Convergence why the time is right for intelligent graphics Web CGM –Vector intelligent technical graphics viewable via browsers ATA CGM –Vector technical graphic data interchange proven to be reliable across applications and platforms Industry graphic style guide –The industry accepts visual communication standards e-Business –Provides opportunities to link to / from customer information processes Human issues –The modern mechanic has less time, is relatively inexperienced but more computer literate

9 4 Key Business Strategies Quality Controls –from 14 to 26 secondary and 50 tertiary vendors per program reliable digital data and quality controls Change Process Management –4 revisions per year 50,000 revisions to illustrations during publications life structured graphic data and efficient change process Engineering Synergies –50% of all publications work is research synergy between publications and engineering Single Source Graphics –Each illustration tells a unique story –Each illustrated component is the same component based illustrating

11 Why CGM? Platform independent ISO standard Web enabled Industry profiles available Efficient data sizes Conformance test suites established Large existing legacy data sets

12 CGM Standard (ISO/IEC 8632) Version 1 The original 1992 standard -vector data including polygons, lines, rectangles, circles, arcs, text plus uncompressed raster data. Version 2 Corrections to v1 and some minor improvements Version 3 Advanced curves support (Bezier, conic arcs, B-splines), improved text handling, line attributes, raster compression, more colour models. Version 4 Application structures that enable intelligent graphics, more precise line type support

13 CGM Profiles ATA - Air Transport Association GREXchange Graphics Exchange standard for version 1and 3 metafiles - Aerospace industry profile IGEX Intelligent Graphics Exchange standard for version 4 metafiles - Aerospace industry profile WebCGM The intelligent web-enabled profile January 99 - recommended for use by W3C CALS - (Continuous Acquisition & Life-Cycle Support) –MIL-D-28003A Standards for the exchange of military graphics for technical publications PIP - Petroleum Industry Profile Geophysical and trace mapping usage with extensive use of colour and patterning. SAE (Society of Automotive Engineers) SAE J2008 Profile

14 The quality triangle Squeezing through the quality loop ISO 8632 Industry Profile NIST & syntax checkers Goodness

15 Goodness How can a syntactically correct CGM not be good? Line styles Text alignment Circles and curves Layers - corporate handshakes Colour precision Line continuation Inherited quality issues A B A Q LOSS CGM CGM

16 Supplier Graphic Data Typical problems differing visual clues uncertain locations confusing detail huge fragmented CAD files different layering schemes CGM fonts scaling colour maps line fonts ellipses masks fragmentation huge CAD files

17 Graphic Style About 50% of supplier errors are style related Why does it matter? –Visual communication –Goodness controls –Visual coding –Use of illustration fragments Cost versus Quality –$2m+/ yr in Aerospace spent reworking graphics for style purposes (1997 ATA Survey) –Limits reuse of illustration fragments ATA Graphics Style Standard –Recommended for use in 2000 –Created by all major manufacturers and component vendors with input from AECMA. –In use now within Aerospace community

25 Strategies in Re-purposing Graphics for Intelligent Delivery Business issues Standards, goodness, and style Delivering efficiency to the customer Internal efficiencies Engineering interfaces Summary

26 Graphics Creation new tools -- old methods ATA graphics are primarily visualizations of maintenance and operational tasks Static depiction of optimal sequence of procedure 50% of creation time spent in search of engineering drawings/models/change drivers Orientation of 3D models and 2D orthographic drawings to task-specific view

27 Graphics Creation new tools -- old methods ATA graphics are primarily visualizations of maintenance and operational tasks Static depiction of optimal sequence of procedure 50% of creation time spent in search of engineering drawings/models/change drivers Orientation of 3D models and 2orthographic engineering drawings to task-specific view

28 Graphics Creation (cont) new tools -- old methods Extraction of geometry 2D-3D & HLR, part metadata is typically not captured Context is not saved, re-used, must repeat process - task configuration (BOM) and orientation Illustrated components/fragments not reused -nowhere-used of part in (SGML/XML) task instance Intelligence in graphic is manually authored Customer Support-specific attributes not at source

29 Intelligent Gfx Creation & Revision Capturing component intelligence from: –Engineering design data CAD/CAM/PDM Maintenance View of product structure needed – subset of complete bill of materials - LRUs & SSIs Geometry (both 2D and 3D where existing) static & kinematic visualizations Transport (via XML) metadata elements used by Customer Support: –e.g. part number, material spec, CAGE code, service effectivity, interchangeability (1 & 2-way)

30 Intelligent Gfx Creation & Revision (cont) Supplier data –Supplier Engineering data –Supplier Product Support (SGML/XML/CGM) Legacy illustrations - leverage commonality of parts –30% for derivative programs Automating grobject creation for legacy Gfx –Using scripts to find patterns (text/fonts/layers) –Revisit CAD conversion process - extract native entity attributes, serialize to XML –Direct linking to source PDM intelligence

31 Opportunities for Efficiency Gains Reduction of research activities (50% of current efforts) Build task-specific views of product structure automatically, save as context –IPC becomes customer support Bill of Material Reusing detail views and components –increases reuse by a factor of 200 –average of 2.5 locator views per sheet –improves consistency and reliability of data

41 Organizational Change Process –authoring more rigorous –graphics much more structured –link resolution needs to be validated –revision cycle more complex –create once use many Human Issues –are publications staff equipped and ready for change in work process?

42 XML the metadata key transporting engineering metadata from partners/suppliers transporting product support metadata from partners & suppliers transporting data between de-coupled departmental databases Design ==> Manufacturing ==> Customer Support transforming SGML to XML and XSLT for Web presentation

43 SGML-XML-WebCGM based IPC PUBLISHING dBase GRAPHIC\ dBase SGML/XML EDITOR SHEET 1 SHEET 2 META DATA SHEET 3 V4 IMBEDDED ON CALLOUTS LINK MANAGEMENT DOCUMENT LINKS LINK RESOLUTION EXTERNAL LINKS PARTS ORDERING GRAPHIC POOL PUBLICATIONS DTD PARTS LIST IMPORT WEB CGM/XML INTERNAL ILLUSTRATIONS TEMPLATES SUPPLIER ILLUSTRATIONS ENGINEERING PSD or SAP dBase LEGACY PUBLICATIONS XML TRANSFORMATION PARSE STYLESHEETS CGM v CGM v4 INTELLIGENT GRAPHIC AUTHORING APPLICATION AUTO LINKING SCRIPTS LINK RESOLUTION PUBLISH CD-ROM WEB WEB LINKS SGML

44 Summary the time is right WebCGM as core graphic format –supplemental formats:.avi,.mpeg,.jpeg,.svg etc.. WebCGM can support static paper as well as interactive media: Web-CD-ROM-DVD WebCGM and XML enable essential quality controls – batch goodness checking possible on structured graphics XML facilitates metadata linking to graphic objects XML enables synergy between related standards: –Maintenance Steering Group (MSG-DTD), Component Reliability Data Collection (CDRC) Validate, STEP Engineering BOM

45 Summary Achieve most accurate, up-to-date snapshot of A/C configuration in a highly dynamic change Design Customer Support authoring/delivery systems with regard for end-user needs, provide the maintenance and flight crews: – right data – at the right time –in the media most appropriate to the task
