CD enabling IT, design technology and tools

New design technologies are used to foster efficient cross-disciplinary analysis, experim entation, and representation of new product designs, e.g.:

  • three-dim ensional ( 3 -D) com puter-aided design ( CAD)
  • sim ulation
  • digital m ock-up
  • rapid prototyping ( RP)
  • stereo projection.

Their 3 -D rendering:

  • allow s the expert to interpret design features,
  • im proving com m unication,
  • reducing m isunderstandings,
  • helping to find solutions

For CE to be successful, inform ation and interpretation “asym m etries” am ong the experts m ust be avoided, w henever possible

SESSION

Approach:

  • Multidisciplinary
  • Holistic
  • Systematic
  • Centralized
  • focus on Customer

expectations

  • …

Methodology:

  • iterative presentations
  • debate

Process Elements

– Conducted in sessions – plenary m eeting w here representatives of all space engineering dom ains participate from early phases ( requirem ent analysis) to end of design ( costing) – 6 to 1 0 session / study, 4 hour / session, bi-w eekly frequency – team leader ( or facilitator) co-ordination – custom er participation – Model driven – On-line design – Highly co-operative & interactive – I terations – Design options com parison and trade-offs

CDF dynamics – Centralised architecture

Process:

  • Specialist “k” performs

an estimate and shares data in CR

  • Data is available to
  • ther specialists
  • Each specialist can use

this data to perform calculations and share the results …

  • x. System makes budgets
  • y. Overall process iterates

…

  • z. Final design done, all

information available in CR

Benefits

  • Perform ances:

(for typical pre-Phase A study)

  • Study duration (Prel.

design phase): 3-6 weeks (cp. 6-9 months!)

  • Factor 4 reduction in

tim e

  • Factor 2 reduction in

cost (for the Customer)

  • I ncreased nr of studies

per year, compatibly with max 2 parallel studies

  • Quality im provem ent,

providing quick, consistent and complete mission design,

  • incl. technical feasibility, risk,

programmatics, cost

  • Technical report becom es

part of the specs for industrial activity Note: Cost report remains the ESA independent reference

  • Capitalisation of corporate

know ledge for further reusability

  • Requirem ent consolidation
