THIS VOLUME EXAMINES THE INTERRELATIONSHIPS BETWEEN THE SYSTEM TECHNOLOGY AND DISPATCH OPERATIONS FROM AN OPERATIONAL ANALYSIS VIEWPOINT TO DETERMINE POTENTIAL BENEFITS AND TO IDENTIFY CRITICAL PERFORMANCE PARAMETERS. AN ANALYSIS OF THE PERFORMANCE OF SIX COMMERCIAL SYSTEMS IS ALSO PRESENTED. IT IS FOUND THAT THE BENEFITS OF AUTOMATIC VEHICLE LOCATION CANNOT BE FULLY REALIZED WITHOUT AN EFFICIENT DISPATCH SYSTEM, AND THAT SYSTEM PERFORMANCE PARAMETERS ARE UNIQUE TO EACH LAW ENFORCEMENT OPERATION. TWO AREAS WHICH MERIT FURTHER INVESTIGATION AND DEVELOPMENT ARE IDENTIFIED AS A COMMUNICATIONS PROTOCOL RELATED TO OPERATIONAL DEMAND AND SYSTEM DEFINITION GUIDELINES TO ASSIST INDIVIDUAL LAW ENFORCEMENT AGENCIES IN THE DETERMINATION OF SYSTEM PERFORMANCE REQUIREMENTS. FOR ALL FOUR VOLUMES, SEE NCJ-36198 THROUGH 36201. (AUTHOR ABSTRACT MODIFIED)
