The production planning problem:
From lead times and clearing functions to partial differential equations

Prof. Dieter Armbruster (Arizona State University, USA)

Abstract:
Determining the production rate of a factory as a function of current
and previous states is at the heart of the production planning problem.
Different engineering approaches to this problem are reviewed and their
relationship is discussed.The concept of a clearing function is introduced
and identified as the moment closure for a first principle approach based
on kinetic transport theory.  Necessary conditions for the success of the
clearing function approach, as a practical tool based on a quasi-steady
state  approximation,  are  presented  and  more  sophisticated  approaches
allowing the prediction of outflow in transient situations are discussed.
Open loop control solutions to the deterministic production problem are
introduced and promising new research directions are outlined.
