shipment_capacity_consumption::Vector{Float64} # can include several independant capacity consumptions: as weight, value, volume

Since product_quantity is now a range, how can we know in advance the capacity consumption?
A solution (that augments the complexity of DS) is to define in product a tuple (step, cons) where consumption means the marginal capacity that product consumes when passing from step k to k+1. step is a quantity of product.
