Steering strategic decisions at London underground: evaluating management options with system dynamics

System dynamics simulation models provide a powerful and rigorous means of evaluating management options in dynamically complex settings such as a metro subway system. We explore how a system dynamics model has been used over several years to address a variety of management challenges at London Underground. Several short case illustrations are described to demonstrate how such models are used in practice to aid strategic decision making, carry out robust business planning, and communicate effectively with key stakeholders.
