ldquothe process of designing a model of a concrete system and conducting experiments with this model in order to understand the behaviour of a concrete system andor to evaluate various strategies for the operation of the systemrdquo (Shannon 1975)Discrete Simulations The assumption is made that all state changes of the simulation model happen in a discrete event in time Hence nothing happens between two neighboring points in time So the simulation run is a finite sequence of model states

Continuous Simulations By contrast state changes continuously in this kind of simulation for example chemical processes Describing models for this type of simulation normally ends up in finding fitting equations

The Essence of Improvement

3

ldquowhen you can measure what you are speaking about and express it in numbers you know something about it but when you cannot measure it when you cannot express it in numbers your knowledge is of a meager and unsatisfactory kindrdquo Lord Kelvin 18831048708 If the objective of a project is to improve efficiency and lower costs how does one measure and demonstrate those improvements without a clear baseline metrics for thecurrent state and realistic target metrics of the future state
