Advantages and Challenges of Remanufactured Products
Zenodo (CERN European Organization for Nuclear Research), 2022
Remanufacturing is the process of restoring discarded goods and components to a brand-new, technologically sophisticated state with the least amount of waste and expense. In a rebuilt product that incorporates the technological advancements deemed required to ensure that repairs may be completed promptly and the item is returned to functionality in an efficient manner, non-wearing parts are reused. This review article provides an overview of the remanufacturing process. the significance of it, how it contributes to sustainability, and a list of difficulties with product remanufacturing. When industries adopt new technologies for component restoration, higher material recovery, and even the retention in-house of competencies that could have previously been outsourced, the scope and benefits of remanufacturing expand. However, its drawbacks are also explained.

Abstract: Remanufacturing is the activity which combines the profitability and the benefits of the sustainable development, trough reducing the landfills and virgin raw material consumption, energy and specialized labour used in production. Remanufacturing should be approached under two aspects: the remanufacturing of the technological equipment that is during exploitation or in preservation, and which were not designed for remanufacturing and approaching the remanufacturing in the conception stage of the technological equipment.

Design for remanufacturing: What performances can be expected?
International Journal of Environmental Technology and Management, 2012
The objective of this report is to supply first of all a state of the art on the consideration of the remanufacturing on one hand in the ecodesign methods and on the other hand in the reverse supply chain management (RSC). These states of the art show that the available methods of ecodesign take into account little the potentialities of the remanufacturing notably because of the difficulty considering products with multiple life cycles (notion of upgradability). They show on the other hand that the RSC management and the ecodesign methods are considered rarely simultaneously. A case study conducted on an espresso machine completes these states of the art to accentuate the various dimensions of the remanufacturing problem. All these elements reveal the necessity of giving to the design team, a method helping to develop new concepts of remanufacturable systems.

Development of an assessment model to increase the understanding about remanufacturing applicability
2015
Remanufacturing can offer benefits to manufacturing companies and service industry, as well as for customers and the society. However, to make progress, the awareness of this potential and understanding of the applicability is too low both in industry and society. Customers also often do not have a confidence in remanufactured products as they do not know the quality principles of remanufacturing. Thus remanufacturing activities are still quite uncommon. This was seen also in a Finnish research project, in which new industrial resource-efficient collaboration forms, including remanufacturing were studied. It is clear that not all products or parts can be remanufactured in a reasonable way, but so far remanufacturing is far from its potential. One reason is that companies do not know if remanufacturing would suit to their business, if the products can be remanufactured or not, and if the customers would accept remanufactured products. As a whole, it is not known what needs to be take...
A Review on the Lifecycle Strategies Enhancing Remanufacturing
Applied Sciences, 2021
Remanufacturing is a domain that has increasingly been exploited during recent years due to its numerous advantages and the increasing need for society to promote a circular economy leading to sustainability. Remanufacturing is one of the main end-of-life (EoL) options that can lead to a circular economy. There is therefore a strong need to prioritize this option over other available options at the end-of-life stage of a product because it is the only recovery option that maintains the same quality as that of a new product. This review focuses on the different lifecycle strategies that can help improve remanufacturing; in other words, the various strategies prior to, during or after the end-of-life of a product that can increase the chances of that product being remanufactured rather than being recycled or disposed of after its end-of-use. The emergence of the fourth industrial revolution, also known as industry 4.0 (I4.0), will help enhance data acquisition and sharing between diff...
Remanufacturing in automotive industry: Challenges and limitations
Journal of Industrial Engineering and Management, 2011
Purpose: The aim of this paper is to provide the framework for management of reverse flow of materials in automotive industry. The emphasis is placed on the remanufacturing activities. Materials management in such conditions is a real challenge. The cause for this is parallel use of raw materials and reused materials. Such hybrid flows of materials are characterized by increased level of uncertainty connected with amount, quality and timing. Design/methodology/approach: This paper presents a comprehensive review of remanufacturing and traditional manufacturing. The stabilization of reverse flows is crucial for continuity of remanufacturing operations. The simulation model and results are discussed regarding stabilization of the reverse flows. Findings: Authors identify main problems that appear in the area of combining at the production system forward and reverse flows of materials. The agent-based technology is applied for configuration and stabilization of reverse network. Research limitations/implications: Paper is case -oriented. Practical implications: Both logistician and IT researchers might benefit from authors approach. Journal of Industrial Engineering and Management -http://dx.doi.org/10.3926/jiem.2011.v4n3.p453-466 -454 -Originality/value: Authors provide an interdisciplinary approach combining operations management, logistics and information technology.
Remanufacturing: A key enabler to sustainable product systems
Rochester Institute of Technology, 2006
Along with the increase in the standard of living, energy consumption, and the consumption of other nonrenewable material resources have grown to unsustainable levels. Closing the loop on the material flows associated with product or service delivery to consumers is an important step towards a more sustainable industrial society. One element of an overall product life-cycle strategy that can aid in achieving this goal is product remanufacturing. However, the full societal benefits of remanufacturing can not be achieved unless design for remanufacturing becomes an integral part of the product development process, both at the product strategy level and the detailed product and manufacturing engineering level.
Remanufacturing Process Planning
Remanufacturing is an active area of research due to its cost saving capabilities and emission-reduction benefits. After being disassembled, cleaned and inspected, the core components go through a series of reconditioning operations before being reassembled into the final remanufactured product, and tested to ensure quality. However, used core components have varying conditions, different defects, etc., which result in reconditioning process paths being specific to each component in the core. The reconditioning process sequence for a core component depends on its conditions. This paper analyses the conditions of the core components to determine an optimal reconditioning process sequence for these components
BOOK REVIEW
Remanufacturing: Modeling and Analysis
Mehmet Ali Ilgin and Surendra M. Gupta
CRC Press, Taylor and Francis Group LLC, Boca Raton, FL, 2012,
ISBN: 9781439863077, 413+ XXV pages
As the authors state in the preface of the book, “the collected EOL (end of life) products are transported to a remanufacturing plant where they are disassembled into parts. Following the cleaning and inspection of the disassembled parts, repair and replacement operations are performed to deal with defective and worn-out parts. Finally, all parts are reassembled into a remanufactured product, which is expected to function like a new product. In addition to repair and replacement, some parts or modules may also be upgraded while remanufacturing a product” (page xix).
Remanufacturing is not the only option to treat the EOL products by various industries in their attempts to observe the ever more strict regulations meant to ensure an environmentally friendly manufacturing to the largest extent possible and to gain higher economic efficiency. Besides remanufacturing, other possible options for recovering valuable parts or materials are repairing, reconditioning or recycling. The authors remark that remanufacturing, if possible, is the most promising and effective option not only with respect to environment related regulations, but also to expected financial gains. A variety of other benefits of remanufacturing can be envisaged, such as: energy and material savings, job opportunities for retired and laidoff factory workers, possible up-graded performance of the remanufactured products and so on, while a less monotonous and creative work is expected as well (page 5). According to the authors, "there are 70,000 remanufacturing companies in the United States creating $53 billion per year income, and nearly half million people are employed by these firms (page 3).
In the context briefly described above, the authors propose a book meant to address the most significant issues of the domain which “can serve as foundations for researchers to build bodies of knowledge in these fast growing areas of remanufacturing systems” and
help the industry people to utilize the models proposed in solving the practical problems they encounter (page 389).
The book is the result of collaboration of two authors who are well known among the academic people for their publications in the domain of “green manufacturing”. Dr. Ilgin received his PhD degree in industrial engineering from the Northeastern University in Boston. His scientific interests include, among others, the environmentally conscious manufacturing, product manufacturing, reverse logistics, simulation and so on.
Dr. Gupta is with the Northeastern University in Boston where he is a professor of mechanical and industrial engineering and the director of the Laboratory for Responsible Manufacturing. His scientific interests include, among others, operational research, engineering economy, supply chain management and production planning and control. He is the author/coauthor of over 400 technical papers, journal articles and books. For his remarkable teaching and research activities he received several recognition tokens, such as the Industrial Engineering Professor Award and an outstanding research award from his university.
The majority of over 400 pages of the book describe models and techniques frequently presented in the industrial engineering texts adapted here to address and solve typical problems which can be encountered in remanufacturing activities, such as design, planning and processing. The book is organized accordingly in five parts as it follows:
Part I, entitled “Background” is composed of two chapters meant to set the stage for the examples and models to be presented in the subsequent chapters by describing the application domain and techniques envisaged to be utilized. The first chapter contains a general presentation of the characteristic features of the manufacturing systems. The second one
reviews the majority of the industrial engineering and operation research techniques which are used in the more than one of the subsequent chapters such as: Taguchi Loss functions, AHP (Analytical Hierarchy Process), TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), goal programming, fuzzy logic, linear physical programming, house of quality, line balancing methods, simulation, experimental design and orthogonal arrays, MOST (Maynard Operations Sequence Technique), linear integer programming, non-linear programming, queuing theory and genetic algorithms.
Part II, entitled “Design Issues”, comprises four chapters to address relevant design aspects of the products, reverse and closed-loop supply chains, as well as the selection of used products and evaluation of remanufacturing facilities.
Part III, entitled, “Planning Issues”, is made up of 13 chapters. It starts by describing, in details, several techniques utilized in forecasting, job sequencing and inventory management. Then, other examples and techniques are presented concerning capacity planning, pricing methods,
control mechanisms (including adapted Kanaban and Multi-kanaban systems), uncertainty and product acquisition management, supplier evaluation, optimal supplier portfolio, selection of third-party reverse logistics providers and performance measurement.
Part IV, entitled “Processing Issues”, is made up of four chapters. Chapter 20 contains various heuristic models to be used in the disassembly processes. Cleaning, inspection and reassembly issues are addressed in chapters 21 through 23.
Part V, entitled “Epilogue”, contains the conclusions of the book which reiterate several ideas exposed in the preface and chapter 1.
This book is a very good introduction to the problems and reported results in the domain of remanufacturing industries. It can be a valuable text both for academic people and practitioners from industry. The book may be viewed as a new valuable component of a series of books one author (Prof. Gupta) has prepared together with his colleagues with a view to promoting the methods and techniques for sustainable manufacturing.
