IT UTILIZED BOTH ENGINEERING AND LEGAL SKILLS TO PRODUCE A MATHEMATICAL MODEL OF THE INDIANA CRIMINAL COURT SYSTEM AS IT OPERATES IN SOUTH BEND AND INDIANAPOLIS. THIS SIMULATION MODEL FACILITATES EVALUATION OF THE EFFECTS OF PROPOSED CHANGES IN THE SYSTEM WITHOUT ACTUALLY INCURRING ALL THE COSTS WHICH USUALLY MAKE SUCH EXPERIMENTATION PROHIBITIVE. ALTHOUGH THE STUDY WAS AIMED AT TWO PARTICULAR COURTS, SOME OF THE PROBLEMS RAISED AND TENTATIVELY ANSWERED AND THE SIMULATION PROGRAM ITSELF WILL APPLY, WITH MODIFICATION, TO OTHER COURT SYSTEMS. THE ENGINEERING SECTION CONTAINS AN ANALYSIS OF THE CAUSES OF DELAY IN THE CRIMINAL COURT SYSTEM BY USING MATHEMATICAL MODELING. USING INCREMENTAL TIME FACTORS AS THE DATA CRITERIA, THE REPORT MATHEMATICALLY DESCRIBES CRIMINAL COURT CASE PROCESSING AND LOCATES THOSE SYSTEM ELEMENTS WHEREIN DELAY IS A SUBSTANTIAL PROBLEM. SUGGESTIONS ARE THEN OFFERED FOR THE IMPROVEMENT OF CASE PROCESSING AT THOSE SYSTEM POINTS.
