This paper deals with stockpiling of various ferroalloys in the National Defense Stockpile. The purpose and philosophy of stockpiling various forms of strategic and critical materials for national defense emergencies are discussed in addition to a historical review of the background and history of stockpiling various ferroalloys.

The methodology and econometric computer modeling used to calculate the overall stockpile quantities are described as well as the method used for calculating specific quantities of each ferroalloy. The potential pitfalls and problems associated with changes in specifications, industry usage patterns, and geographical shifts in production centers are included in the discussion.

The results of the use of the new methods and the effects on future stockpiling plans are presented.
