Different Modelling Purposes

Bruce Edmonds, Christophe Le Page, Mike Bithell, Edmund Chattoe-Brown, Volker Grimm, Ruth Meyer, Cristina Montañola-Sales, Paul Ormerod, Hilton Root, Flaminio Squazzoni
2019 Journal of Artificial Societies and Social Simulation  
How one builds, checks, validates and interprets a model depends on its 'purpose'. This is true even if the same model code is used for di erent purposes.  ...  they simply developed the model without a specific purpose in mind.  ...  However, just because a model for one purpose suggests a model for another, does not mean it is a good model for that new purpose.  ...

Modelling the Dynamics of Ships with Different Propulsion Systems for Control Purpose

Witold Gierusz
2016 Polish Maritime Research  
Two different propulsion systems are analyzed from point of view of future control applications. The traditional one consists of a pushing single screw propeller and a blade rudder.  ...  Unfortunately, the way the systems work is somewhat different and each of them should be modelled separately.  ...  The modelling of such system was properly performed and has rich bibliography. Nowadays a different propulsion system has become more and more popular.  ...
