"Approximate Dynamic Programming
and Control of Queueing Networks with
Re-entrant Lines"

Our research on ADP has focused on the control optimization problem of simple benchmark queueing networks with re-entrant lines and under the discounted cost criterion.

Experiments with ADP algorithms have demonstrated that these are able to provide close approximations to the optimal policies.

"Optimization of Preventive Maintenance
Scheduling for Semiconductor Manufacturing
Systems: Models and Implementation"

Preventive Maintenance (PM) is a vital activity in semiconductor manufacturing. A good PM schedule can increase the availability of tools by trading off between the planned unproductive down time versus the risk of much costlier unscheduled down time due to tool failures.
