Technical Field

[0001] The present invention relates to the technical field of supply chain management data analysis, and specifically to a supply chain management data analysis system and method based on machine learning. Background Art

[0002] Supply chain management involves optimizing supply chain operations. It involves coordinating internal and external resources to meet consumer demand. If we consider the various companies in the supply chain as a virtual alliance, and each company as a department within this alliance, then the internal management of the alliance is supply chain management. However, the composition of the alliance is dynamic, constantly changing based on market demands. Supply chain management requires segmenting customer segments based on the service characteristics they require; designing logistics networks based on customer needs and profitability; listening to market demand information to design products that are more customer-centric; managing time delays; strategically determining sourcing and establishing win-win partnerships with suppliers; establishing information systems across the entire supply chain; and establishing performance evaluation criteria for the entire supply chain. Existing supplier selection in enterprise supply chain management often relies on manual selection, failing to intelligently and dynamically select suppliers based on analysis of supplier supply behavior characteristics, compromising the scientific nature and security of enterprise supply chain management.

[0003] A Chinese invention patent with announcement number CN104574024B discloses an ERP remote zero-inventory supply chain management system.
