INVENTORY CONTROL FOR NON-REPAIRABLE ITEMS BASED ON PROGNOSTICS AND HEALTH MONITORING DATA

摘要

In an improved inventory control policy and associated data processing system, effective inventory level is compared with a variable reorder point, R(t). When the effective stock is lower than the reorder point R, a new order of Q units is placed. Also, the lot size is optimized for each order. Parameters R and Q are continuously updated based on Remaining Useful Life (RUL) estimations obtained from a Prognostics and Health Monitoring (PHM) system.
