      Dear Mr. Spence:

           During a meeting with representatives of your staff on August  12, 1971,
      we discussed an inventory management technique that can be used by  the
      Government Printing Office to reduce its levels of stored paper  stock. We
      are bringing this matter to your attention because you expressed  to us that
      you would welcome suggestions for increasing the efficiency of Printing
      Office operations and because you may wish to give this matter your  personal
      attention.

           We recently inquired into the basis used by the Printing Office  to de-
      termine levels for paper stockage.  The Printing Office has an established
      reorder point for each item in its paper  stock. The  reorder point is calcu-
      lated by multiplying the average monthly usage by a month  factor that varies
      for each item and ranges from 2 to 6.  This means  that on-hand and on-order
      levels are not intended to fall below  the equivalent of 2 months' usage for
      some items and 6 monthst for others.  A major weakness  in the method used to
      determine the month factor is  the heavy reliance on personal judgment and
      the little use of readily available historical data.

           To test our observations, we selected  three frequently used items:
      offset book paper (property number  10087), white writing paper (property
      number 205), and United States postal card paper  (property number 1139).

           We introduced historical data covering  a 2-1/2 year period into a com-
      puter simulation of Printing Office operations.  The data  included factors
      such as purchase order dates, quantities ordered  and received, receiving
      dates, and daily usage.  We projected  the simulation forward 5 years.  Our
      analysis of simulated inventory activity  showed that the Printing Office
      could substantially reduce its reorder points without  running short of pa-
      per.  Our study indicated that existing  inventory practices may be resulting
      in unnecessarily large cushions of  stock on-hand or on-order.

           The inventory model which we developed  provides a method for determining
      reorder points and quantities of paper to be purchased  that is more efficient
      than one relying heavily on peisonal  judgment. The model  used for each of
      the three items we selected  is adaptable for use for all paper items purchased
      by the Printing Office.

           Based on our review of these  three items, we estimate that the Printing
      Office may be able to reduce  its total investment in paper inventory by
      about $2 million, or 23 percent of the Printing Office's  paper inventory
      investment, by using the model to calculate  reorder points and purchase
      quantities.  We have not attempted  to estimate the amount of savings that
      may accrue from reductions in  storage and related costs.
