This study examined fifteen automotive casting suppliers who display a significant degree of disaster risks to a major automotivecompany in the USA. All of the suppliers are capable of producing the same items for the company. As illustrated by the sensitivity analysis, potential increases in VAR due to the suppliers’ disaster risk profiles are significantly greater than potential decreases based upon an examination of individual VAR values in the last two columns in Table IV. The data in these columns reveal that the potential VAR percent increase is approximately ten times the potential percent decrease in VAR for a given supplier. This result implies that the company should focus its efforts more on disaster preparedness to mitigate the impact of a supply chain disaster on revenues. These efforts may include seeking alternative sources of supply for critical items, the possession of buffer inventories stored in strategic locations, and the ability to make adjustments to its product mix based on the availability of materials.
