Structured systems analysis was used to develop the specifications for a computer based system for scheduling production and controlling inventories of traffic signs. Data flow diagrams were used to depict the flow of data in the system. A field inventory data base is used in conjunction with reflectivity decay data to identify signs which are candidates for replacement. These candidates are input into a system which plans the activities of roadway crews that are responsible for traffic related activities. The output of the roadway crew activity planning subsystem corresponds to the demand for traffic signs. The demand, which is in fact derived from the activities of the roadway crews, provides a forecast of future Sign Shop demands. The Sign Shop utilizes the forecast to develop production schedules which support the forecasted activities of the roadway crews.
