I am writing an LCA where some of the parts need to be replaced and have different lifespans (5,2,15 yearss) I am currently writing it for 20 years, so this takes into account replacing some of the parts but not all of them.

Is there a way where I can set up my product system so that I can easily switch from studying a 10 year timeframe to a 20 to a 30 without having to manually add in all the extra parts and EOL processes

well so basically you need the parts more often for the product (e.g., 16 tires for the life cycle of a car) - you can set a parameter for the amount of parts needed for, e.g., the car, then you can quite easily change it.

- you can also do this in a more "sophisticated" manner, e..g building  a yearly car and then simply multiplying this by the number of years
