Hello. You did not inform the situation to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
An extended supply chain alone will be advantageous if the establishment needs to supply large commercial chains, such as large supermarkets and regional centers. Otherwise, a shorter supply chain will be more advantageous, as it will have less costs that will be offset by a low number of networks.
A supply chain refers to a network of commercial institutions interconnected and organized in such a way that one is able to supply the other, whether in raw material, transport or manufactured products.
