characteristicsof models
● not complete 1:1 mapping
● want to focus on certain aspects
● different views of same thing6/22

iconic model● ‘look’s like what it represents
● specific relationship to what it represents● e.g. scale – down or up
● can never share all properties

analogue model
● iconic model not convenient
● properties of a different kind● economy - bath

symbolic model● abstract
● uses symbols● words, numbers, variables, graphical
● can handle large complex descriptions

variables
16/22
● quantitative - qualitative● temperature - comfort
● evaluation
● prediction

model building● what has to be modelled
● select kind of model for purpose● decide on components
● test and validate

model building

if modelnot adequatethen results
will not match reality

model building
19/22
● model must represent all variables● if something missing - distortion
● all variables must be relevant● not just because data available
● be aware of distortions● use of different materials
● be careful of data entered● G I GO
