Abstract
A COMPUTER PROGRAM, CODED IN GPSS, HAS BEEN WRITTEN TO SIMULATE THE OPERATION OF THE ST. LOUIS METROPOLITAN POLICE DEPARTMENT'S REAL-TIME MOTOR VEHICLE INQUIRY SYSTEM. FOUR TYPES OF INQUIRIES ARE HANDLED - VEHICLE (OR LICENSE) CHECKS, AND ADDITIONS, DELETIONS, AND MODIFICATIONS TO STORED INFORMATION. COMMUNICATIONS CHANNELS, FOUR COMPUTERS, AND ELEVEN TERMINALS ARE EXPLICITLY REPRESENTED IN THE SIMULATOR. OTHER SYSTEM EQUIPMENT AND TYPES OF INQUIRIES ARE IMPLICITLY REPRESENTED. FOUR EXPERIMENTS WITH THE SIMULATOR ARE REPORTED. THESE INVOLVE CHANGES IN TERMINAL EQUIPMENT, THE MESSAGE ASSEMBLY PROCEDURE, THE PRIORITY SYSTEM, AND SYSTEM LOADING. (AUTHOR ABSTRACT) BIBLIOGRAPHY
