Calculation of indicators

The calculations of the material-related indicators are based on a common material list, well-defined and common material properties, and calculation rules for each EPI.

• The design describes how the train is composed of different parts in a component structure.
   

• Each component is broken down into smaller pieces until materials in the REPID material list are reached.
   

• The calculations of the material related indicators are based on properties of the materials in the material list.
   

• By using algorithms described in the definition of each indicator, the properties for the materials in the analyzed component are aggregated and a score for the indicator in the component is reached.
   

• The evaluated score for a specific design can be compared to a target value for the design. An indicator can be calculated for any part in the component structure.
