A new computer program, developed by a team from Lehigh University, that matches inmates with suitable prisons has saved the Pennsylvania Department of Corrections about $3 million in its first year. Officials said it has resulted in fewer prison assaults, shortened wait times for treatment programs by nearly two months, reduced the number of prison transfers and lightened the workload of corrections staff. In recognition of their development, the Lehigh University team has received the INFORMS Wagner Prize, the top international prize in the field of operations research practice.
