Abstract
A technical description of a proposed inventory and procurement policy for ordering and allocating maintenance and operating supplies throughout the Deep Space Network is presented. This policy differs from the conventional economic lot-size procurement policy in that the reorder point for the Network Supply Depot (NSD) depends upon the stockage levels at all area station or Complex Supply Facilities (CSF), as well as on the level at the NSD. Thus, by basing reorder decisions upon the state of the inventory supplies throughout the entire DSN, an efficient cost minimizing policy is possible. Safe minimum inventory levels are established for each CSF by means of statistical decision theory techniques which require NSD to reorder whenever one or more of the CSFs reaches its prescribed minimum. Some results of a statistical study of the effect of this policy are included.
