The design of an integrated production and inventory control system for a traffic sign shop
The West Virginia Department of Highways (WVDOH) is the agency responsible for maintaining the state's roadway system. One of the activities involved in this responsibility is to supply traffic signs for newly constructed highways and to replace those signs that are either deteriorated, stolen or damaged. To continually provide these signs for installation in the field, the WVDOH maintains ten warehouses (districts) in different locations in the state, and a central sign shop which produces and distributes signs to these districts. This thesis describes the logical design for an integrated system to control the inventory and the production of the WVDOH central sign shop. The objective of this proposed system is to provide management with a decision support tool for 1) controlling the orders issued by the district, 2) planning, scheduling and controlling the production at the sign shop, and 3) planning and controlling the raw materials and subcontracted parts inventory. The logic for this system was developed using structured architecture. The proposed design is documented in the form of data flows diagrams, a data dictionary, and process narratives. This integrated system will provide WVDOH management information that will enable them to reduce inventory levels at the districts and central sign shop, improve production lead times, and reduce signs shortage. The implementation of such system will also reduce manual work in planning and controlling the inventory and improve information accuracy.
