Computer simulation is a well established technology applied to both system design and process improvement. Computer simulation modelling involves building a model of a machine, process or a whole system using specialised software tools such as the ARENA simulation modelling system. This model will respond to given inputs much as would be expected in the real world. Using it one can "experiment" testing various ideas and options to get an understanding of how the real system would behave in certain situations. It can be used to establish mobile equipment requirements, size infrastructure (bins, stockpiles, conveyors, plant, LNG trains, FLNG, etc), trial new control strategies or to see how the system will perform at different loads or product mix.
Using ARENA, a realistic animation can quickly and easily be added. This allows decision makers to see the model in action, giving confidence in its accuracy as well as an understanding of the dynamics of the system being modelled. It is very much a matter of seeing your ideas in action.
In short, simulation permits better decision making by giving managers the ability to explore options and "try out" proposals before making any real commitment.
