Chapter 2 REVIEW OF RELATED WORKS
2.1 EXISTING BLOCKCHAIN BASED SUPPLY CHAIN FRAMEWORKS
The system of organizations, individuals, activities, knowledge, and resources involved in moving a product or service from supplier to customer is referred to as the supply chain management processes [39] and blockchain has been identified in both academia and industry as having the potential to transform the supply chain industry and improve information flow.
Supply Chain Management (SCM) is described by the Council of Supply Chain Management Professionals as "the planning and management of all activities involved in sourcing and procurement, conversion, and all logistics management activities." Coordination and collaboration with channel partners, such as suppliers, intermediaries, third-party service providers, and customers, is also important. Supply chain management, in essence, combines supply and demand management within and across businesses [40].
SCM covers all procedures, processes, and entities involved in fulfilling the customer's product or service requirements. In today's world, supply chain management is a vital component of the industry. SCM has advanced dramatically in recent decades, with several and important transformations and developments in supply chain sub-processes. Enterprise Resource Planning (ERP), over the last two decades, has been known to positively impact businesses and supply chain performance and we see this in the popular adoption of ERP among multiple organizations and businesses [41].
ERPs have unquestionably changed the way organizations work internally by offering a shared forum for various organizational divisions to collaborate to maximize preparation and resource efficiency, such as production planning, warehousing, inventory, and delivery [42]. However, since this system is centralized, it is vulnerable to a single point of failure. It also suffers from a lack of product visibility and accountability, lack of traceability outside the organization's network, product security and integrity problems, and dispute resolution issues related to contract breaches and standard enforcement. Cloud computing has also been proposed to facilitate spare parts supply chain management and operations [43, 44]. Authors give various benefits of integrating cloud computing into the supply chain however also state Security concerns and loss of irreplaceable data can lead to mistrust among supply chain members and customers.
