(4) VALIDATION / 7

Quantitative Validation (continued)

• Aim to demonstrate model capable of reproducing measured behaviour.

• Necessary to specify suitable acceptance levels.

• Do model predictions need to be within 5% or 50% of measured values?

• At least 2 types of qualitative validation:

  (a) using historic data ? modeller has full knowledge.
  
  (b)“blind” predictions ? modeller does not know solution.
  

• Acceptance levels probably different.
