Abstract

Disclosed are programs which control the design and manufacturing views of Product Definition data and its distribution from the originating Design Engineering group to one or more manufacturing organizations. Essential elements of the invention include: - Uniqueness of the Design View The design view permits time-controlled versions. Each Engineering Change represents a time-controlled version of the Design Data. However, no two Engineering Controlled versions are valid at the same time. Thus there is, for any time selection, only one design version of the data which can be selected. - Multiple Manufacturing Views Each manufacturing organization can create its own version of the design data. This Manufacturing View is based upon the Design View, but additional manufacturing defined data may be added.

Support of Multiple Manufacturing Product Definitions from a Single Engineering Design Definition in a Single Node Implementation

       Disclosed are programs which control the design and
manufacturing views of Product Definition data and its distribution
from the originating Design Engineering group to one or more
manufacturing organizations.  Essential elements of the invention
include:
-    Uniqueness of the Design View
      The design view permits time-controlled versions.  Each
Engineering Change represents a time-controlled version of the Design
Data.  However, no two Engineering Controlled versions are valid at
the same time.  Thus there is, for any time selection, only one
design version of the data which can be selected.
-    Multiple Manufacturing Views
      Each manufacturing organization can create its own version of
the design data.  This Manufacturing View is based upon the Design
View, but additional manufacturing defined data may be added.  There
may be many manufacturing views valid "at the same time." Selection
of manufacturing data requires specification of the view (along with
time-oriented version selection).
-    Data Distribution
      Data must be distributed from the Design View to appropriate
Manufacturing Views.  In addition, the capability to define which
data may need to be distributed to remote computer systems is
provided.  Control of distribution is linked with status and
promotion mechanisms.
-    Control of Design Integrity
      The manufacturing view may deviate from the original design
view.  Mechanisms are provided to adjust the amount of deviation (to
meet the requirements of various enterprises).  In addition,
mechanisms are provided to allow follow-on Engineering Changes to the
design to propagate to the Manufacturing Views.  Note that this is
not a trivial process, since the follow-on Engineering Change is a
delta to the previously established base design, and manufacturing
may have altered that base design with its view.

      In many enterprises, the design and production of physical
products is handled by different organizations.  These may be
separated by reporting structure, by geography, by tradition, or, in
many cases, the design group may work for a different company than
the manufacturing organization.  This business organization places
constraints and requirements on any information system which
communicates design information from the design group to the
manufacturing group.  Since the design group is not ultimately
responsible for the manufacture of the product, there are certain
decisions which it cannot make.  These typically include the actual
break-in date of manufacturing production of a particular design, and
the sourcing of raw materials or subcomponents needed in the product.
In addition, certain details of the design related primarily to the
manufacture, such as process design, may be left up to the
manufacturing organiz...
