Proposes an expert system approach to routing and scheduling school buses for a rural school system. The expert system is programmed in TURBO PROLOG for use on an IBM/XT and is applied to rural county school systems in Alabama. The routing problem is concerned with the determination of a stop-to-stop route to be traversed to each school by each bus whereas the scheduling problem, the determination of times at all bus stops for each bus. A bus may be used for multiple runs. Each route is designed in such a way that the bus capacity, student riding time, school time window and road condition constraints are satisfied while attempting to minimize the number of buses required in operation, minimize the fleet travel time and balance the bus loads. The knowledge base contains factual knowledge such as road map, school locations, bus capacities stop locations, number of students at each stop, and drivers' homes. It also contains procedural knowledge such as heuristics for finding a route and scheduling multiple runs for a bus subject to various constraints. The inference engine or control program chooses the appropriate heuristics used in constructing efficient routes and schedules with respect to various objectives or goals. A user interface includes the graphic display of road maps and determined routes
