The problem arises when those responsible for a team of Formula One have to decide under what car setup will give the best results. This configuration is different for each circuit where the car has to compete. During the season each team selects a circuit that does not have to be one where you compete during the season, either by proximity to the car parts maker or by the climatic conditions of the area. In this circuit are obtained based configurations, in which the car gets good results.
These original settings are used as a starting point, when deciding which configuration right to compete in a given circuit. Depending on the technical characteristics of the circuit will choose one of the basic configurations that have team leaders.
The factors that have to decide one or the other settings are:
-
Tire Camber
-
Height of fins.
-
Weight distribution.
-
Suspension stiffness.
-
Ratio (Marches).
-
Vehicle height to the ground.
-
Engine speed level.
-
Braking distribution.
For each circuit these factors have a greater or lesser influence on the results that would set the car on the track.
Therefore this problem is considered multi-rate, since we must choose the best option depending on more than one criterion, which can be resolved through ELECTRE method.
