Simulation – An Environment Simulator for the FDNY Computer Aided Dispatch System
•MICS System – Management and Information Control System
•Environmental simulator – an integral part of the MICS
•Six modes of operation: alarm receipt, decision dispatch, display/fallback, notification, status monitoring and management
•Results showed that the required performance of the MICS system was more than adequately met

MICS designed to replace manual dispatch procedures and to improve the effectiveness of the Department’s operations MICS designed about dual PDP-11.45s and supported in fallback by dual INTEL 8080 microprocessors
It processes alarms received by telephone, new electronic street boxes and older mechanical street boxes.

FDNY required an emergency simulator to be included in the system. The simulator consists of an offline scenario generator, an online load generator module and a performance monitor module FORTRAN used to develop the simulator

Alarm receipt – the system receives the alarm, from one of the possible sources.
Decision dispatch – an automatic determination is made regarding the appropriate response
Display/Fallback – visual aid to the dispatching process or automated fallback system. Provides a geographic map of the coverage area displaying the availability of the resources
Notification – notifies the resources about the emergency
Status monitoring – monitors the status of both the units and incidents
Management – a variety of functions that are performed as support to the dispatching process – information retrieval, data recording, message switching, load generation, performance monitoring etc.

The system was tested using various simulations. Some hardware deficiencies were found in memory management and software overhead. The environmental simulator was used as the vehicle to ascertain the system acceptance criteria for MICS. It was used to drive the system under peak alarm conditions (3 alarms per minute). Results were satisfying.
