A Prototype Decision Support System for Two-Stage Facility Location in ConnDOT's Maintenance System

This report describes a prototype decision support system (DSS) that has been designed to help ConnDOT investigate alternative maintenance facility configurations. The use of the DSS specifies which repair facilities and roadway garages to keep open, and the DSS determines the optimal assignments of garages to repair facilities and roadway sectors to garages. The engine of the DSS is based on a linear programming model of the two-stage maintenance system. Although the prototype system models only ConnDOT's second maintenance district, there are no technical problems associated with expanding it to include the entire state. To make the DSS more user-friendly, a geographic information system (GIS) interface has been designed. The link between the GIS component and the linear programming model is described, but implementing the link for the prototype system was not part of the current project. Further work that would be required to complete a DSS that covers the entire state and that incorporates a GIS is described.
