He's assisted with the logistics for airlines and shipping ports, but a chaired
professor in the School of Industrial and Systems Engineering is now responsible
for ensuring the Yankees play the Red Sox in September.

Schedule-makers
deal with conflicting requirements and preferences as a matter of course,
but as the financial and competitive stakes in athletics at the college
and professional level rise, so does the complexity of creating a balanced
schedule. George Nemhauser * a mathematician and a sports fan * noticed
it could benefit from specialization.

He's a partner
in a company called the Sports Scheduling Group, which has handled athletic
scheduling for several college conferences, including Tech's own
Atlantic Coast Conference for nearly a decade. The objective, he said,
is to balance the requirements of the television contract with competitive
fairness while accommodating the needs of fans, coaches, players, media,
sponsors and facility operators.

For some time,
Nemhauser and his partners have had their eye on Major League Baseball,
which lets companies submit proposed schedules and selects the best one.
After several attempts, the office announced last fall it was awarding
SSG the scheduling contract through 2006.

Compared with collegiate
scheduling, though, baseball is another order of magnitude. In fact, the
complexity of the task makes it too large to handle as a whole. Developing
a viable schedule, he noted, involved 12 high-performance computers running
virtually non-stop for five months.

"It's
a wildly constrained process and to come up with something feasible is
very difficult," he said. "Perhaps IBM's Blue Gene computer
could handle something as big and complicated as this, but I doubt it."
