ABSTRACT. In this paper, a new order review/release
(ORR) method is proposed for shop floor control systems. The
proposed method utilizes both job due date and shop load information
to improve the effectiveness of the ORR function in production
systems. The performance of the new method is compared to those
of a few well-known ORR methods under four experimental conditions.
The results of extensive simulation experiments indicate that
the proposed method is superior with respect to the mean absolute
deviation measure. In general, it is also better than existing
methods for the other performance measures. Furthermore, we show
that the proposed method is more robust to variations in system
load and processing times than the other ORR methods examined.
