Cutting down various losses by means of supply chain management, on one hand, increases efficiency of supply chains, but on the other hand, decreases their robustness. Nowadays, supply chains involve various risks such as natural disasters and system failures. It is, therefore, essential to evaluate the risks and to devise countermeasures as supply chain risk management (SCRM). However, manufactures can not necessarily identify the complete supply chain structure, and this interferes with the implementation of SCRM. This paper proposes a method to evaluate the cost effectiveness of the countermeasures against the risks of the parts based on the bill of material (BOM) without identifying the suppliers. The method is applied to hard disk drive manufacturing to verify its effectiveness.
