Integration of warranty as a decision variable in the process of recertification of parts resulting from end-of-life system dismantling

Abstract

In this paper, a new approach to determine optimal disassembly plan of an end-of-life system by using Bayesian network is introduced. The best solution is called the optimal trajectory. A trajectory model is proposed which allows handling the different key factors and also makes it possible to manage uncertainties specific to system deconstruction. After having presented the disassembly planning issue, Bayesian networks instantiated to dismantling problem are introduced together with the influence diagram which allow the decision maker to proceed to the economic assessment of the different possible strategies. Among the various cost factors is the cost related to warranty of the recycled products. A warranty program management is described. Eventually, the global trajectory model, including the implementation of the warranty cost has a decision variable, is presented.

State of the art review of quality, reliability and maintenance issues in closed-loop supply chains with remanufacturing

“…Perceived risk is mostly influenced by quality knowledge, followed by cost knowledge. Godichaud et al (2011) introduced a new approach to determine optimal disassembly plans for an EOL system by using Bayesian network. They also proposed a risk management workflow.…”

“…In these cases, after sale factors such as discount, warranty, availability of parts, repairs and other additional services play a role. In such a situation, these factors will be very noteworthy to the buyer, especially the warranty since it further assures the buyer of the reliability of the product [10]. The objective of the warranty is to promote the product's quality and guarantee its performance to assure both the remanufacturer and the buyer.…”
