Over the past twenty-five years there has been a significant reduction in U
K iron and steel making capacity. This has happened primarily as a result o

ences of this strategy is offered by means of a system dynamics model. It c
onsiders both short and long term effects and represents an aid to learning
in the face of the complexity which characterises manufacturing operations
