The production planning problem:
From lead times and clearing functions to partial differential equations
Prof. Dieter Armbruster (Arizona State University, USA)
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.
