In computer simulation a spread sheet package, a computer program using high level languages or a simulation package is used to represent the system under consideration. It is very useful when dealing with complex systems and enables the prediction of short, medium and long term behaviour of the system being modelled.
Some systems diagramming tools also have simulation capability.
CAD systems are examples of product simulation. They can also be used to simulate certain manufacturing situations such as clash detection when using automatic assembly systems. |
In manual simulation the system is represented by a desk top model and is manipulated by hand to simulate its behaviour. Significant data is logged, allowing further analysis. It is of particular use when sufficient understanding of the real-world problem is not available. It is a particularly useful tool for training operating staff because it gives hands-on experience.
Manual models can also be used for executive training ‘games’ such as scheduling or demand management that help managers understand the pros and cons of different methods.
A popular child’s building brick toy has been used to great success for manual modelling and ‘games’. |
