Many different types of models but Ackkoff (1962) proposes three categories:
- iconic model – expected to behave same as real thing. e.g. scale model of ship or model aircraft in wind tunnel.
- analogue model – attempt to simulate behaviour without necessarily replicating physical appearance. e.g. computer games like Forza and FIFA.
- analytical model – developed from mathematical or logical relationships connected to a situation of interest. e.g. input to a simulation such as MS Flight Simulator.
Could also add conceptual model as demonstrated in previous unit.
These models represent subjective or qualitative aspects of situation. Diagrams such as mind maps or rich pictures also fall into this category.
