Abstract
Given a product design and a repair network a level of repair analysis lora determines for each component in the product 1 whether it should be discarded or repaired upon failure and 2 at which echelon in the repair network to do this The objective of the lora is to minimize the total variable and fixed costs We propose an ip model that generalizes the existing models based on cases that we have seen in practice Analysis of our model reveals that the integrality constraints on a large number of binary variables can be relaxed without yielding a fractional solution As a result we are able to solve problem instances of a realistic size in a couple of seconds on average Furthermore we suggest some improvements to the lora analysis in the current literatureThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
