BOM based supply chain risk management

Although the application of supply chain management to reduce various losses increases the efficiency of supply chains, it decreases their robustness. Nowadays, supply chains involve risks such as natural disasters and system failures. Therefore, it is essential to both evaluate the risk and devise countermeasures as supply chain risk management (SCRM). However, manufacturers have difficulty identifying the complete supply chain structure, and this interferes with the implementation of SCRM. This paper proposes a method to evaluate the potential risks associated with the parts of products on the basis of the bill of material (BOM) without identifying suppliers. We applied this method to hard disk drive manufacturing to determine its effectiveness.
