An Analysis of an Inventory System for Interchangeable Recoverable Items

摘要

The objective of this grant was to study the interchangeability/substitutability problem for recoverable items and to develop methods for managing interchangeable recoverable items. Research has led to a full understanding of the behavior of a single-echelon, two-item system over an infinite horizon when the failure times are independent, stationary Poisson processes and the repair times are exponential. Approximately optimal policies for managing this system have been found. These methods have been extended to methods for finding approximately optimal policies for managing the single-echelon system with several interchangeable recoverable items.
