Internet has influenced the application of supply chain model in three aspects. Firstly, the Internet promotes the use of enterprise resource planning (ERP) and advanced planning and optimization system (APS). Secondly, enterprises can establish a detailed (high-density) supply chain model by obtaining real-time information and accessing large computer systems, and use it to make real-time decisions. Thirdly, the internet provides opportunities for information integration and decision-making among multiple departments of enterprises, and then provides enterprises with the need to break through departmental restrictions and extend their learning. This has promoted the role of supply chain model, making it rise from a tool to promote decision-making to a tool to promote enterprise strategy. Therefore, the Internet has greatly enhanced the role and analytical position of the supply chain model in enterprises.
