The Problem & Solution
Acquisi'on Life Cycle Pre-‐Systems Acquisi0on (PSA) Time Systems Acquisi0on (SA) Problem: Single user CAx* and the related heterogeneous
data force the acquisition life cycle into a serial set of
process activities.
Solution:
Multi-user+ CAx and neutral data will “layer,
shrink, and collapse” life cycle times by N simultaneous Time/N clients.
*CAx = any computer-aided engineering application (CAD, CAE, FEA, CAPP,
CAM, etc.)
+Multi-user
= multiple clients can edit a single CAx model
simultaneously.

Single User CAx Tools NOT Collaborative
•  CAx is the productivity bottleneck….one
CAx model, one person to edit the model.

Delivery Times Increasing?
“There has been about a threefold
increase in delivery time for most major
systems...puzzling given enormous
productivity advantages conferred by…
Internet and e-mail…advances in
knowledge-management and
collaboration tools such as..(CAD)..
(CAM)..”
(From Pre-Milestone A and Early-Phase
Systems Engineering: A Retrospective Review
and Benefits for Future Air Force Acquisition,
National Research Council, 2008)
So when do you expect to
finish the design?
Soon!
If I could just figure out
how to merge the
surfaces. …..

Relevance
Example
Warfighter readiness for the Air Force, Army, and Navy is
limited by single user CAx and related data heterogeneity.
•  The problem is complicated by a growing supplier
chain using different file-based CAx applications.
Example: Boeing uses ~6,450 suppliers (down from ~10,000 in 1997); Goodrich (now UTAS) and PPG
Aerospace are 2 Boeing Tier 1 suppliers each with supply chains listed in the 1,000’s, …, ultimately the
leaves of the Boeing supply chain touch small manufacturing firms with minimal CAx tools, and untold
model conversions and delays to get them access to the Boeing (or UTAS or PPG) data. File based
uniformity translations like IGES, STEP, JT, etc., are architecturally not the solution.
•  BYU’s multi-user CAx prototypes reduce modeling
times and inherent data interoperability.
$1 billion per year and two months of delays on each new US automotive model
attributed to CAx interoperability.

Primary Objective
Using a consortium of prime defense contractors BYU
will develop a CAx application-neutral and data-neutral
architecture (database) and prototype for a single-source
of all engineering and manufacturing data used in multiuser CAx.
