“…For this, the circular economy is based on the following schools of thought: (i) Biomimicry (Benyus, 2009), study of nature to design goods and to develop new technologies; (ii) Industrial Ecology (Despeisse et al, 2012), study of the material and energy flow through the industrial system to add value to waste produced by a firm; (iii) Cradle-to-Cradle (McDonough and Braungart, 2010), design of goods in harmony with environment and communities through the term "nutrients". In our previous works (Diez et al, 2015), we propose an approach of these concepts through the notion of "regeneration paradigm". The regeneration term comes from the food web that is circular and reuses all that is produced by each entity being a part of trophic organization.…”

“…This cycle is repeated indefinitely and regulates itself. In (Diez et al, 2015), we have shown that by applying the same principles to the industrial world, it is necessary to add processes to play the role of decomposers, called "technical decomposers" or "decomposition processes". Unlike to the industrial ecology where companies exchange their waste to use them like resources, the technical decomposers transform unusable items to add them value.…”

“…(Foundation Ellen MacArthur, 2014;Govindan et al, 2014) identify four technical decomposers: repair, reuse, remanufacturing and recycling processes. In (Diez et al, 2015), we have added a new decomposer, called detechnification, to create a link between industry and nature. Indeed, when a product cannot be regenerated in the industrial world, it is put back in nature.…”

Sustainable development is increasingly present in the international political powers. In response, the circular economy is increasingly emphasized. This economy is also called regeneration paradigm. This paradigm uses a multitude of concepts, which makes it complex to understand. Indeed, it makes each stakeholder (nature, decomposers and user companies) interact amongst themselves to create an industrial ecosystem. However, they sometimes have requirements that oppose. Therefore, this paper proposes a regeneration management tool to coordinate all of these stakeholders. For that, the regeneration requirements are identified. Then, they are modeled to understand their impacts on the product lifecycle and on the company business. These models are based on system dynamics that has been developed to enable a better understanding of complex systems.

Maintenance best way for meeting the challenge of regeneration

The circular economy is an economy that meets sustainable requirements, and that advocates a new paradigm, the paradigm of regeneration. This paradigm allows creating new businesses, new jobs and new skills all along about the product lifecycle. This is especially the case for maintenance and retirement processes. Indeed, these processes are the regeneration core. Those of retirements do not sum up to destructuring process but match also with repair, reuse and disassembly processes. As for maintenance, it becomes the cornerstone of all this. Through all its current skills, it allows managing and optimizing the regeneration by deciding when to stop a use and where studied items should go. Besides, maintenance must adapt to the regeneration. In other words, tools and methods used by maintenance can be able to maintain the regeneration potential of an item, and thus, create new jobs and experts. The purpose of this paper is to highlight the major challenges brought by the paradigm of regeneration to maintenance.

“…L'état d'un composant permet de décider le cycle (i.e. maintenance, réutilisation, régénération, recyclage de sa matière ou retour à l'écosphère (Diez et al, 2015)) dans lequel le composant peut être réintroduit et donc impacter de manière non linéaire son prix de revente. Cette décision nécessite alors une quantification de la capacité de l'élément, i.e.…”

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.
