THE GOAL SYSTEM version 2.2 is the latest in a lineage that
includes Optimized Production Technology (OPT) and DISASTER.
Earlier work with DISASTER revealed potential shortcomings with
sequential schedule-building algorithms when multiple interactive
constraints exist. Since THE GOAL SYSTEM version 2.2 has a capacity
for simultaneous schedule-building, this study evaluated
differences between the two algorithms. Using benchmark scheduling
problems developed during the earlier evaluation of DISASTER, a set
of THE GOAL SYSTEM solutions was created and compared
quantitatively to both DISASTER solutions and solutions which
optimally minimize maximum tardiness. A broad set of performance
measurement criteria were also used to obtain a more comprehensive
evaluation of the solutions. Performance of THE GOAL SYSTEM was
quite good with respect to maximum tardiness. Performance with
respect to average flowtime, percentage of tardy jobs, and total
days late for a set of job orders was markedly poorer than the
DISASTER solutions. The results were unexpected, since the
simultaneous scheduling algorithm is less restricted in its options
for schedule creation. The author concluded that the simultaneous
feature of THE GOAL SYSTEM was better suited for conflict
resolution during an iterative process than as a stand-alone
scheduling algorithm.
