Hi there!
Since this is your first post, you might want to start by reading: Please read: make it easier to help you
At the moment this is a little too generic of a question.
If you can post a small reproducible example with the (simplified) code of what you currently have, then people should be able to help, but this might be a good starting point:
using DataFrames
client, plant, product, amount = [], [], [], []
for j in 1:J
for i in 1:I
for k in 1:K
push!(client, i)
push!(plant, j)
push!(product, k)
push!(amount, q[j, i, k]
end
end
end
DataFrame(
client = client,
plant = plant,
product = product,
amount = amount,
)
