“…In some industries, consumers may not differentiate between new and remanufactured products. However, this is not always the case as despite the fact that remanufactured products are typically sold with a warranty equivalent to that of a new product [1,7], consumers still have concerns about the quality of remanufactured products [1] so view them as inferior. The paper considers substitution strategies for a company selling new and remanufactured products to its customers.…”

“…Remanufacturing is the process by which products are restored to an "as-new" condition [1]. Remanufacturing and more broadly, product recovery, have received an increasing amount of attention recently as governments [2,3], businesses [4,5,6] and consumers become more aware of the importance of sustainability and reducing the impact on the environment.…”

Increasing legislative and societal pressures are requiring manufacturers to operate more sustainably and to take responsibility for the fate of their goods after they have been used by consumers. A hybrid remanufacturing system, in which newly produced and remanufactured used goods are sold on separate markets but also act substitutes for each other, is described and modelled using a semi-Markov decision process. The model provides an optimal policy, which specifies production, remanufacturing and substitution decisions. The model is used to explore the properties of this hybrid remanufacturing system, and in particular, the managerial implications associated with upward and downward substitution.

RÉSUMÉ. Dans ce travail, nous présentons une première étude sur la planification du processus de désassemblage prenant en compte les états ou qualité des produits à désassembler. Nous proposons une approche qui permet de définir le meilleur niveau de désassemblage en fonction du coût occasionné pour désassembler le produit et de l'état du produit et/ou les états de ses composants et sous-assemblages. L'état d'un produit est modélisé par le concept de Potentiel d'Utilisation Résiduel (PUR) pris comme variable aléatoire normale connue et tronquée. Le problème est modélisé sous forme de programme stochastique. L'objectif est de maximiser le profit du processus de désassemblage, qui est la différence entre les revenus des composants et sous-assemblages et les coûts des tâches de désassemblage. Les revenus sont définis comme fonctions de PUR. L'approche développée est testée sur deux exemples de la littérature pour analyser l'impact de l'état d'un produit sur la planification de son processus de désassemblage.ABSTRACT. This paper adresses the problem of disassembly process planning taking into account the quality or states of the product to be disassembled. We propose an approach which is able to return the best disassembly level for a product considering the disassembly cost and the state of the product and/or the states of its subassemblies or components. The state of the product is represented using the concept of « Potentiel d'Utilisation Résiduel (PUR) » which is assumed to be a Gaussian random variable with known truncated distribution. A stochastic program is proposed to model the problem with the objective of maximizing the disassembly process profit. The latter is calculated as the difference between the positive revenue generated by recovered parts and the costs of the disassembly tasks. The revenue of a recovered part is a function of PUR. The developed approach is tested on two example case studies from the literature to analyze the impact of uncertain product quality on its disassembly process planning.MOTS-CLÉS : désassemblage, désassemblage partiel, qualité produit, incertitudes.

“…The exact number of process and sequence depend on the nature of used-products being remanufactured (Ilgin & Gupta, 2012). The four process can be further expanded to twelve processes, as reported in Boustani (2010) to include (i) warehouse of incoming used-products, parts, and outgoing remanufactured products, (ii) sorting of incoming used-products, (iii) cleaning of used-products, (iv) disassembly of used-products and subassemblies, (v) inspection of used-products, subassemblies, and parts, (vi) cleaning of specific parts and subassemblies, (vii) repair or renewal of parts, (viii) testing of parts and subassemblies, (ix) reassembly of parts, subassemblies and products, (x) testing of subassemblies and finished products, (xi) packing, and (xii) shipping.…”

Remanufacturing is an important production activity, which is mainly driven by the increasingly strict environmental regulations imposed by governmental bodies, growing customers' awareness of green environment and potential economic benefits of remanufacturing. In this paper, the key motivating factors for companies to engage in remanufacturing program are examined. The major sources for acquiring used-products and the subsequent markets for selling remanufactured products are also examined. More importantly, the generic-key remanufacturing processes are examined and the corresponding unique characteristics are highlighted. Four examples of remanufacturing process of different products are presented to demonstrate that exact number and sequence of remanufacturing process largely depended on the type of product being remanufactured. In sum, this paper presents an overview of used-products remanufacturing, which in many ways would benefit the general public, environment, manufacturers/remanufacturers, as well as researchers.
