The matrix process for control of the custody population in Oregon prisons is described.
Abstract
The goal of the matrix process is to control prison overcrowding within standards established by the Federal Court but without endangering the community. All criminal charges and holds are ranked by seriousness and given a points score. The scores are entered in a computerized booking and population management system. A subprogram including all matrix elements is written and interfaced with the larger computer systems. Upon booking into custody, an inmate is classified by the staff on the computer system, regarding type of housing and behavior alerts such as assaultive, escape risk, unstable, gang membership, or psychological problems. The matrix score changes with addition of new charges or negative behavior in custody. When the population approaches capacity, the Population Release Office reviews a computerized list of potential releases in a score ranging from the lowest of 14 to a high of about 70. Pretrial or sentenced inmates can be matrix released on pass or furlough under two community supervision programs.
