System Mean-Time-between-Failure versus Life-Cycle Logistics Cost Subject to the Introduction of Line-Replaceable-Unit Redundancy

Abstract

This document presents an examination of ten alternate system designs in which redundancy is employed to achieve various values of system mean-time- between-failure (MTBF). In serial system designs where line-replaceable-units (LRU's) possess exponentially distributed times to failure, life-cycle logistics cost is inversely proportional to system MTBF. In this analysis, this phenomena was found to be contradicted. Life-cycle logistics cost is directly proportional to system MTBF, in the presents of LRU redundancy and no preventive or scheduled maintenance.
