Optimum-AIV
- Description : Planning and Scheduling of Spacecraft Assembly, Integration and Test
- Client : European Space Agency
Abstract
A consortium consisting of Computer Resources International A/S, Matra
Marconi Space, Progespace and AIAI was responsible for the development
of the European Space Agency (ESA) knowledge based system for the
planning and scheduling of activities for spacecraft assembly,
integration and verification (AIV). The system supports the entire
AIV life cycle, i.e. not only scheduling of the activities but also
monitoring of plan execution and the plan repair phases. State of the
art knowledge based techniques have been applied in the
planning/scheduling process: preconditions and effects on the
spacecraft configuration of individual activities can be stated and
used for verification of the plan logic. The system allows scheduling
of activities to be performed either manually or automatically using
resource levelling. The system was delivered to ESA/ESTEC last year.
OPTIMUM-AIV is now being operationally applied to the strategic planning of
the production of ARIANE IV equipment bays. This activity frequently requires
the plans to be updated due to non-availability of equipment, test failures,
etc.
