The talk reports on an active research study which highlights the contribution of maintenance modelling to high-tech steel production. A stochastic O.R. model is developed of the behaviour of plant under different maintenance systems, along with the consequences to production.

Simpler modelling options are possible, but the increased insight into both the engineering and management aspects derived from the stochastic approach are highlighted. The study is a collaboration between O.R. scientists, statisticians and engineers.
