Dear Alie Wube Dametew,

Can you rephrase the question so that understanding better.

Any company has supplier/suppliers and customers. So supply chain already processing. If you want to design a SC system for suppliers threre are so many research paper available in research gate.

Dear Vadivel S M

Yes of-course any supply chain systems have these three levels structure that is supplier manufacturer and customer. This is the normal way of supply chin integrations.

but the question is during supply chain process the focal company found in the position of supplier segment, do this real supply chain? and which type of systems they follow? this is the main concepts

Thank you

In the supply chain there should not be a single supplier, if we have only one we would have very dangerous vertical integration that could affect the actions of our company. It is advisable to establish strategic alliances with some suppliers always looking to win.

I am certainly concur with Cadena Jaime's answer.

Vertical integration with one or several suppliers can generate problems in the supply of raw materials and inputs, I believe that we must work strategically with all those involved in the value system, from raw materials to the final consumer

Thanks all

I agree on the concepts on

Cadena Jamie .

Typically, the focal company/ manufacturing company found with a network of suppliers, supply chain management is about relationship management. In this stage, the position of the focal company determines a certain number of tiers and a number of suppliers for each tier. Each of these suppliers supplies critical raw materials to the next company (customer). While automobile company owns a tire company. Or the Carnegie Steel Company owned mills where the steel was manufactured, mines where the iron ore was extracted, coal mines that supplied the coal, ships, and railroads that transported the material, etc. this is a form of vertical integrations. Commonly, in a vertical integration two or more firms that operate in different stages of the manufacturing process to integrated for Saving transport costs, faster and more secure access to primary products, utilizing resources to their full capacity and protection of quality. But, an automobile manufacturer buying a sport service vehicle manufacturer is more close to horizontal integrations.
