Level of Repair Analysis a Tool for Integrated Optimization: A State of Art Review

Abstract

This work provides an overview of level of repair optimizations addressed in the field of system design reliability and maintenance planning for fleet architecture. The review provides the detail in reliability design and various aspects of fleet maintenance planning viz., analysis of repair options, preventive maintenance optimization, and inventory level optimization. The interdependencies among all these decisions are also discussed. The scope of this work is to highlight the inputs from the literature. The gaps identified from the literature are also mentioned. The focused literature related to reliability design, analysis for LOR and multi-indenture inventory parts optimization has been reviewed. Literature related to joint consideration of these planning aspects in fleet system is also discussed. The literature review has helped in identifying recent work in the field of reliability design and fleet maintenance planning.
