Computer simulation of adult sentencing proposals

Several legislative proposals have been introduced in the State of Washington which would alter sentencing procedures for adults convicted of felonies. A major policy concern is the degree to which such new legislation would impact population levels in an already overcrowded prison system. The Sentencing Alternatives Impact Simulation Project developed a series of computer simulation programs to model the sentencing proposals. Results of the simulations were made available to the Legislature and to planners for Adult Corrections. This article describes the major model developed, the data required to run it, and the results obtained from it under a variety of hypothetical conditions. It includes a discussion of the level of utilization made of the results, and some comments on the requirements for maximizing utilization in future simulation projects.
