Process Planning and Production Scheduling for Affordable
This research, supported by Lockheed Martin Missiles and Space,
is part of the ASSIST project.
The Advanced Technology Center
is leading the ASSIST project, which is funded by the U.S. Air Force.

At this point we have developed and prototyped IPPS,
which performs integrated production planning and production scheduling
for affordable space systems manufacturing.
We are currently enhancing the system based on feedback from users.
This work has designed and constructed an
integrated planning and production scheduling tool
that can be used to control the manufacture of custom satellite propulsion
The system dynamically creates manufacturing process plans and
schedules the required assembly, integration, and test operations
for all propulsion systems based on material, personnel,
and equipment availability.
Rescheduling is done periodically as conditions in the factory change.
Affordable Space Systems Intelligent Synthesis Technology (ASSIST)
for Manufacturing is an intelligent knowledge management system for
dramatic reductions in cost and time in low volume space system manufacturing.
ASSIST selects collaborative and information management tools that
have been successfully demonstrated in a
stand-alone environment and integrates them in an
innovative and extendible infrastructure.
The resulting environment, which provides a seamless
electronic communication system, overcomes
enterprise-wide manufacturing cost and time
consumption due to limited availability and inefficient use of information.
