A system for planning and controlling a pull-in request of an order with demanded
capacity in a production system. A plan engine is programmed to receive a pull-in
request for the order, release original demanded capacity, reserve a capacity for
the pull-in order, and generate a fixed production schedule for the pull-in order
based on a capacity model that considers a plurality of capacity vectors in the
production system. A production schedule monitor and evaluation module determines
whether the relevant current pull-in order conforms to the fixed production schedule
and whether to adjust the fixed production schedule when the relevant current pull-in
order deviates from the fixed production schedule.
