Designing a Support System for Repairable Items.

摘要

A model is developed which yields the best system design (number and location of repair depots, number of repair channels at each depot and size of the spares inventory at each depot) to service a widely dispersed population of repairable units, subject to random failure. Considered in the design model is a service level constraint in terms of spares availability, as well as purchase costs of spares and repair channels, fixed costs of operating repair depots, and unit repair and transportation costs. Failure and repair times are assumed to be exponential and finite source queueing theory coupled with a branch-and-bound algorithm are utilized in developing the model. (Author)
