The understanding of what constitutes a "good" production schedule is centr
al to the development and evaluation of automated scheduling systems and th
eir implementation in real-world factories. In this paper, we provide a def
inition of a schedule and discuss potential uses for a schedule within the
organization. We then describe a number of different considerations that mu
st be taken into account when assessing the quality of a schedule, and disc
uss their implications for the design and implementation of scheduling syst
ems. Published by Elsevier Science B.V.
