There are a variety of supply-chain models, which address both the upstream and downstream elements of supply-chain management (SCM). The SCOR (Supply-Chain Operations Reference) model, developed by a consortium of industry and the non-profit Supply Chain Council (now part of APICS) became the cross-industry de facto standard defining the scope of supply-chain management.
SCOR measures total supply-chain performance. It is a process reference model for supply-chain management, spanning from the supplier's supplier to the customer's customer. It includes delivery and order fulfilment performance, production flexibility, warranty and returns processing costs, inventory and asset turns, and other factors in evaluating the overall effective performance of a supply chain - wikipedia 
A diagram of a supply chain. The black arrow represents the flow of materials and information, and the gray arrow represents the flow of information and backhauls. The elements are (a) the initial supplier (vendor or plant), (b) a supplier, (c) a manufacturer (production), (d) a customer, and (e) the final customer - wikimedia
The Global Supply Chain Forum has introduced another supply chain model. This framework is built on eight key business processes that are both cross-functional and cross-firm in nature.
Each process is managed by a cross-functional team including representatives from logistics, production, purchasing, finance, marketing, and research and development. While each process interfaces with key customers and suppliers, the processes of customer relationship management and supplier relationship management form the critical linkages in the supply chain.
The Risk-Averse Optimal Position of the Delivery Window (RA-OPDW) is another supply chain model. It was the first model to report that "the optimal position of the supply chain delivery window, which is necessary to achieve supply chain resilience, is neither determined by penalty cost per time unit late nor by the penalty cost per time unit early but by their ratio."
The American Productivity and Quality Center (APQC) Process Classification Framework (PCF) SM is a high-level, industry-neutral enterprise process model that allows organizations to see their business processes from a cross-industry viewpoint.
The PCF was developed by APQC and its member organizations as an open standard to facilitate improvement through process management and benchmarking, regardless of industry, size, or geography. The PCF organizes operating and management processes into 12 enterprise-level categories, including process groups, and over 1,000 processes and associated activities.
In the developing country public health setting, John Snow, Inc. has developed the JSI Framework for Integrated Supply Chain Management in Public Health, which draws from commercial sector best practices to solve problems in public health supply chains.
