Abstract
A material flow control device for controlling flows of a plurality of work species within a production system measures the two-stage engagement amounts and the output amounts of respective work species in respective controlled units, and calculates the evaluation values for respective work species in the respective controlled units as a function of: the difference (or the ratio) of the measured engagement amount and a reference engagement amount; and the difference (or the ratio) of the measured output amount and the reference output amount. The order of dispensation from the upstream controlled units are determined in accordance with the priority determined by the evaluation values for the respective work species.
