A DESCRIPTION OF A TECHNOLOGY TRANSFER PROJECT INVOLVING THE HYPERCUBE QUEUEING MODEL (AN EMERGENCY SERVICES DISPATCHING MODEL) AND THE CITIES OF NEW YORK AND NEW HAVEN (CT).
Abstract
THE HYPERCUBE QUEUEING MODEL IS A MATHEMATICAL MODEL DESIGNED TO HELP MUNICIPAL EMERGENCY SERVICE AGENCIES PLAN THE LOCATIONS AND RESPONSE DISTRICTS OF THEIR MOBILE UNITS. IN NEW HAVEN IT WAS USED TO ESTIMATE A LARGE NUMBER OF PERFORMANCE MEASURES FOR ALTERNATIVE ALLOCATIONS OF POLICE PATROL RESOURCES TO VARIOUS REGIONS OF THE CITY. IN PARTICULAR, THE MODEL WAS USED TO STUDY BEAT CONFIGURATIONS FOR NEW HAVEN'S PATROL CARS. FOR EXAMPLE, IT WAS USED TO FIND THE DISTRIBUTION OF PATROL CAR WORKLOADS AND AVERAGE TRAVEL TIMES, PINPOINT THE BUSIEST AND LEAST BUSY PATROL CARS, AND ESTIMATE THE PROPORTION OF TIME EACH UNIT WOULD BE BUSY SERVICING CALLS UNDER GIVEN BEAT CONFIGURATIONS. THE DESCRIPTION OF THE TRANSFER PROCESS IS PRESENTED CHRONOLOGICALLY, IN A MANNER THAT PARALLELS THE STAGES THROUGH WHICH THE PROJECT PASSED. THE DISCUSSION FOCUSES ON THE PROCESS OF COLLECTING THE DATA REQUIRED BY THE MODEL AND ANALYZING THE MODEL'S OUTPUT. IT ALSO INCLUDES ILLUSTRATIONS OF HOW VARIOUS POLICY ISSUES CAN BE ANALYZED BY VARYING THE MODEL'S INPUT PARAMETERS. PART OF THE TECHNOLOGY TRANSFER WAS ACCOMPLISHED BY USING THE HYPERCUBE MODEL TO EVALUATE ONE OF NEW HAVEN'S EXISTING DEPLOYMENT PLANS, ONE SECTOR AT A TIME, FOR COMBINATIONS OF SECTORS AND FOR THE CITY AS A WHOLE. AN ANALYSIS OF THE RESULTS OF THIS EFFORT IS PRESENTED. THE REPORT ALSO PRESENTS NEW BEAT CONFIGURATIONS THAT WERE GENERATED BY TWO COMPUTER PROGRAMS THAT WERE TRANSFERRED TO THE NHDPS (NEW HAVEN DEPARTMENT OF POLICE SERVICES) IN ADDITION TO THE HYPERCUBE MODEL.
