Decision support system for planning roads construction projects

This paper describes an approach for preparing a road construction project schedule using a knowledge-based DSS. The DSS contains the data on the operations required for the roads construction and helps the decision process during the design of the PERT network, The knowledge base contains graphical elements, such as nodes, representing activities, relationships and decisional nodes. Using this custom-made graphical knowledge, the decision maker generates interactively the PERT network and all the planning data for the project.
