Reliability-Informed Life Cycle Warranty Cost and Life Cycle Analysis of Newly Manufactured and Remanufactured Units

Abstract Standard life cycle techniques such as warranty cost (LCWC) analysis and (LCA) are used to respectively quantify the relative economical environmental advantages of remanufactured goods while simultaneously identifying avenues for improvement. In this paper, we contribute literature on studies by incorporating reliability into LCWC LCA with goal improving long-term/multiple decision making. We develop a branched power-law model incorporate physical degradation mechanisms leading reduced reuse rates system parts over multiple cycles. then follow standard protocol difference between new unit its version in terms impact items abiotic depletion potential, global warming energy consumption. devise four practical policies that vary choice replacement and/or provision extended warranty. All possible scenarios cycles explored each policy mathematically rigorous framework is provided, where information calculate probabilistic items. This reliability-informed enables design engineers compare options quantifying both impacts aid Although presented general form applicable any engineered system, demonstrate utility using case study an infinitely variable transmission agricultural equipment.
