Toward complexity: The impact on the traditional supply chain management by decentralized control — A view from a Supply and Demand Network (SDN)

In the overall control of a classic sense, the producers in the traditional supply chain can have control over the sales agents or retailers and reach the stable equilibrium by wholesale-price plus subsidy contracts. However, when things processed are complex and decision-making decentralizes in various system nodes, the traditional description is definitely inadequate. Thus, this article discusses the impact of the decentralized decision-making and decision-making period on the supply chain and proves that, as a result of the impact, the supply chain system cannot always be optimal.
