LCC : value added and cost

Question

Qui peut expliquer la signification de « valeur ajoutée » et « coût » dans un arbre de contributions ? En d’autres termes, comment sont-ils calculés ? Est-il possible de déterminer le coût de production du produit directement à partir d’un arbre de contribution ?

Answer 1

Better in English but: yes, indeed, the direct costs are also shown in the contribution tree. Often, generic databases do not have good cost data though, if at all. But here an example of ecoinvent costs and the contribution tree:

I understand. So, to perform a good analysis, is it better to update certain costs according to the market? In practice, what interpretation can I make following an LCC of my factory?

Indeed it is recommended to update the costs if you can. Interpretation: LCC is the overall costs of a product (or all products of a factory) seen from the perspective you decide, e.g. the product buyer (if you model from the use phase).

Wonderful. In other words, the direct contribution can be considered as the product’s specific cost of production (cost price).
