Abstract
A computer-implemented system ( ) for task scheduling. The system ( ) models an enterprise in terms of products, tasks and resources used to make them, and constraints imposed in scheduling tasks. A scheduling engine, comprised of a genetic algorithm ( ) and a schedule builder ( ), operates on the model to produce candidate schedules. The schedule builder ( ) uses graph theory techniques to solve tightly constrained scheduling problems. Each candidate schedule is evaluated and used to generate an improved schedule in accordance with genetic processing, until a best schedule is produced.
