Overview
Talk broadly and generally about the systems designprocess at Boeing
- where we think its going
Talk more specifically about several projects using EASY5that are driving in that direction
What are Aerospace Systems ?

Integrating Boeing’s Systems Design EnvironmentWhat Does that Mean ?
Integration of design processes:Preliminary design - Detailed design - Verification and test
Integration of Boeing and vendor/supplier teamsIntegration of Boeing with teaming partners
Cross functional integration
Integration of CAE toolsIntegration of CAD and CAE toolsIntegration with Product Data Manager PDM toolsIntegration of “Single-Source” data
Integrated Systems Design and ModelingWhy ?
Moving towards
Reduced Design Cost & Cycle TimeEarly Systems Validation
Reduced MockupsReduced Testing
Improved Design FlowPreliminary Design to Detailed Design
Integrated System Validation
Cross FunctionalVendors / SuppliersTeams and Partners
Move Towards Single-Source Product DataConfiguration Control
Virtual Prototyping
Other Objectives
Enterprise wide- Common processes- Common tools- COTS tools
- Eliminate legacy codes

Preliminary Design - Detailed DesignThe Tool Dichotomy
PreliminaryDesign
DetailedDesign
- fast- low detail- low skill level
- fully detailed- high skill level
Many tools do not span the design processNeed tools and infrastructure that can “evolve” the designMaybe we need to pay up front with detailed tools that will span the process
- product definition

Supporting Integrated Systems DesignEASY5 Focus Areas
- Improved diagrams and schematics
- CAE tool integrations e.g. GSDS
- Linkages to CAD
- Investigating requirements and structure for PDM
- Real-time
- Develop processes to support teams, vendor/suppliers
- CORBA interface between EASY5 and MAT
- web based
EASY5 DevelopmentDriven by customer Needs
Ongoing Boeing projects driving development
BCA Structures Dynamic Flight Loads
Example - common tools / common models
FlightSystems
Structures
Airframe models
Control system models
Common Analysis Environment
Flight Systems and Structuresengineers see the same picture
The new MAT-based process has been used to compute Flight Loads forall of our commer cial airplane deriv atives since 1996
Example - large-scale process integraton using EASY5 MAT
50% design cycle time reduction - solution phase flight loads analysis
Question - can we achieve similar benefits with our vendors ?
GSDS Auto-code modules may be added as components in EASY5
Integrating GSDS with EASY5BCA Requirements Capture - Detailed Definition - Autocode
EASY5 provides local desktopenvironment for GSDS definitions

In Conclusion
We are involved at high level with process planning, development
We are involved at ground level assisting projects driving both processdevelopment and the development of EASY5
We are striving to expand EASY5’s role as a key tool in the Boeing“enterprise” arsenal of standard processes and tools for
Aerospace Systems Design
