Facing a growing amount of waste electrical and electronic equipment (WEEE), a recent recast of the WEEE directive has put a specific reuse target for manufacturers, aiming to reduce environmental pollution and incentivize a green product design. In this paper, in order to examine whether the above two goals can be achieved by setting a specific reuse target, we have modelled a closed-loop supply chain consisting of a supplier (the leader) and a manufacturer (the follower) with the constraint of a mandated remanufacturing target. In this model, the supplier determines the level of interchangeability in product design and the wholesale price of the key component. The manufacturer buys the key components from the supplier and makes production and remanufacturing decisions under the requirement of a mandated remanufacturing target. We have investigated the supply chain’s members’ optimal decisions and analyzed the impact of the mandated remanufacturing target on the optimal profits of the supply chain’s members and consumer surplus, and finally, we have explored the environmental implications of the mandated remanufacturing target. We found that the supply chain’s members’ optimal decisions are affected by the mandated remanufacturing target and the cost of the new component. In terms of the economic implications of the mandated remanufacturing target, we have demonstrated that the increase in the mandated remanufacturing target has negative effects on the profits of the supply chain’s members and consumer surplus. Regarding the goal of incentivizing green product design, we found that the mandated remanufacturing target cannot always incentivize the supplier to implement product design that is beneficial to remanufacturing. From the perspective of the environment, we further indicate that more stringent mandated remanufacturing targets may bring an undesirable environmental outcome.

Additive manufacturing (AM) is being used increasingly for repair and remanufacturing of aeroengine components. This enables the consideration of a design margin approach to satisfy changing requirements, in which component lifespan can be optimized for different lifecycle scenarios. This paradigm requires lifecycle cost (LCC) modeling; however, the LCC models available in the literature consider mostly the manufacturing of a component, not its repair or remanufacturing. There is thus a need for an LCC model that can consider AM for repair/remanufacturing to quantify corresponding costs and benefits. This paper presents a dynamic LCC model that estimates cumulative costs over the in-service phase and a nested design optimization problem formulation that determines the optimal component lifespan range to minimize overall cost while maximizing performance. The developed methodology is demonstrated by means of an aeroengine turbine rear structure.

The conventional component repair in remanufacturing involves human decision making that is influenced by several factors such as conditions of incoming cores, modes of failure, severity of damage, features and geometric complexities of cores and types of reparation required. Repair can be enhanced through automation using additive manufacturing (AM) technology. Advancements in AM have led to the development of directed energy deposition and laser cladding technology for repair of damaged parts and components. The objective of this systematic literature review is to ascertain how intelligent systems can be integrated into AM-based repair, through artificial intelligence (AI) approaches capable of supporting the nature and process of decision making during repair. The integration of intelligent systems in AM repair is expected to enhance resource utilization and repair efficiency during remanufacturing. Based on a systematic literature review of articles published during 2005–2021, the study analyses the activities of conventional repair in remanufacturing, trends in the applications of AM for repair using the current state-of-the-art technology and how AI has been deployed to facilitate repair. The study concludes with suggestions on research areas and opportunities that will further enhance the automation of component repair during remanufacturing using intelligent AM systems.

Abstract Take the wear parts of coupler knuckle as an example, the “Modeling—Slicing — Stacking” mode remanufacturing process is studied. First, the 3D model of the of the worn coupler knuckle surface is acquired by structured light 3D detection. The remanufacturing model of the failure part is built by Boolean operation between the original model and the acquired 3D model. Second, the user can slice layer of the remanufacturing model according to the remanufacturing stacking parameters. The zone that surrounded by the contour of each sliced layer is the robotic GMAW remanufacturing stack region. Third, the robotic GMAW remanufacturing path is planed within the region mentioned above and the executable program is generated to carry out the remanufacturing task layer by layer. Moreover, the worn coupler knuckle was repaired by adopting Robotic GMAW Process. The mechanical performances of component were tested, the results indicate that the remanufactured coupler knuckle satisfying the operating requirements.

In this study, we assessed the environmental impact of the remanufacturing of mining machinery components, by analyzing commonly used parts in a machine setup. No previous studies have conducted a detailed environmental impact assessment of any manufacturing processes for new or remanufactured components used in mining machinery. We analyzed the system boundaries and conducted inventory analysis to understand their function and determine their unit role in the machine. Then, we evaluated the environmental impacts of the manufacturing processes for the subparts and assy parts, along with the impact of logistic and remanufacturing processes. In particular, we assessed hydraulic equipment, which is a common component of mining machinery, and conducted a comparative assessment of the environmental impacts of new and remanufactured components. Our results indicated that the global warming potential (GWP) per mining machine throughout its lifecycle (LC) could be reduced by ~194 ton-CO2eq./LC. Assuming that the number of mining machinery in operation at a global scale is 571 machines (or units) per year, the GWP would be reduced by ~110,000 ton-CO2eq./year.

Traditional wisdom claims that remanufacturing operations always benefit the manufacturer in monopolistic cases and hurt the supplier in a supply chain system. However, we show that this claim does not hold when firms face a mature market. In particular, we consider a case in which some consumers in the market possess old products before the selling season, i.e., some consumers are holders. A monopolistic manufacturer collects used products from holders and then sells the products to non-holders after furbishing and remanufacturing. In the integrated case, the manufacturer performs manufacturing and remanufacturing together. We find that remanufacturing may hurt the manufacturer when the fraction of non-holders in the market and the production cost are both low. In the separated case, in which an upstream supplier provides the core component to a downstream manufacturer, the downstream manufacturer undertakes the remanufacturing operation as well as manufacturing. We find that the supplier can benefit from the manufacturer’s remanufacturing operation under a specific condition, even if the manufacturer always receives a higher profit.

Remanufacturing is the process of collecting end-of-life products from customers and then being dissembled, reprocessed and reassembled to create new products to meet the customers’ needs. The economic viability of the implementation of a remanufacturing strategy has being shown among many companies in the automobile industry. Also, the economic profitability of the remanufacturing process has been proven in many industrial case studies. Cummins Scania XPI Manufacturing in Södertälje considers implementing a remanufacturing process for their returned components, but there is a lack of a foundation of whether this process will provide an economic profitability or not. In order to decide whether the remanufacturing is profitable for the company, there are some factors to consider. This research aims to identify the reasons behind implementing a remanufacturing process and the factors that affect the economical profitability of it. In order to answer the research questions, a theoretical investigation as well as several interviews with Cummins Scania XPI Manufacturing in Södertälje and Cummins XPJ in Mexico has been done. The aim with the interviews with Cummins Scania XPI in Södertälje was to identify what factors they want to consider when determining whether the remanufacturing process can be economic beneficial for them. The interview with Cummins XPJ was done in order to get an understanding how their remanufacturing process work. The result shows that there can be three main reasons behind implementing a remanufacturing process: economic benefits, environmental benefits as well as legislation. When it comes to the considered factors when implementing the remanufacturing process, the reverse logistic with the aim to remanufacture is important to consider since the remanufacturing is a fundamental process of it. Thereafter the possible factors that can be occurred are one-time costs such as prices of machines, fixed costs such as operators’ costs and where to implement the process. The results of this research provide a possibility for companies to determine whether the remanufacturing process is economically profitable for them.

In an ever changing market that expands continuously and where innovations cycles become shorter, there is an important increase of the renewal frequency of the electrical and electronic equipment (EEE) and vehicles. This makes the manufacture of EEE and vehicles a fast-growing source of waste in terms of used products. The immense amount of information generated by all these technological products which are currently in the market must be managed throughout the whole life cycle of the products. The problem is to provide information about the technological product’s reusability in the recycling process given the colossal complexity of many products and the lifespan of operation. This includes instructions about the components qualifications as elements in a new product. Technologies such as augmented reality (AR) combined with product lifecycle management (PLM) systems can provide the platform for an information system that provides the necessary information and support for the decommissioning process of EEE and vehicles at the end of their life cycle. The present project describes the framework of integration between AR and PLM with the purpose of recycling a technological product at the end of its life cycle. The proposed method of integration could be considered to constitute both an innovation and a possible improvement if compared with the current approach. It is believed that the development of a method that addresses the issue of integration between AR and PLM could provide with a secure, efficient management of stored data related to various products and their properties related to the recycling process at the end-of-life of the product. The result of this approach is an AR-PLM system architecture which assists the circular economy’s recycling process by the use of visual information superimposed on the physical technological equipment.

Owing to the scarceness of natural resources and the increase of the world protection the problem of energy shortage has become a serious issue which has to be deal with nowadays and as a result, the focus of environmental protection has been essentially critical. Therefore, more and more manufacturers and companies are involved in the recycle of used products. This can explained by the following two main reasons: First of all, products with regeneration process are attractive to consumers who possess the concept of environmental protection. Secondly, on account of the restriction of law, manufactures have to effectively recycle and reuse the abandoned old or broken products in order to be beneficial to the environment. Typical production systems have only new products in production line. When manufacturers collect used-products and perform the process of remanufacturing, they use production lines: for producing the new products and the remanufacturing products, respectively, and which are called “Hybrid system with remanufacturing.” It is desirable to establish a suitable strategy for such a remanufacturing system. In this paper, focus it on a hybrid remanufacturing system, we consider related costs with manufacturing and remanufacturing processes to construct a model in determining the optimal strategy of production. In addition, due to the variability of the collection of used-product and competition between the new and the remanufacturing products, we also consider the impacts of capacity constraint, product substitution and limitations of component availability. The model is utilized by the Lingo software to obtain the optimal new product production quantities and the collect rate of the used-product. The expected total profit and remanufacturing quantities can also be derived. Finally, sensitivity analyses are conducted on various parameters to gain insight into the proposed model.

In recent years, due to selling type changing, products lifespan shortening and environmental consciousness resuming, reversed logistics has already become an extremely important issue in the 21st century. In order to promote customer’s service level, cost saving and complying the regulations of government, many enterprises pay attention to reversed logistics more and more. Reversed logistics can be defined as the logistics activities all the way from used products no longer required by the consumers to the products becoming reusable in the market. Reversed logistics is a supply chain with re-designing for managing products that could be remanufactured, recycled, and reused so that the limited resources on earth could be used more effectively. This study develop a remanufacturing profit model with product recycling. The remanufacturing model consists of the processes of product return, disassembly, component remanufacturing and reselling. The model is constructed by profit or cost that includes the remanufacturing cost, acquisition cost, recycling revenue, disassembly and assembly costs, and our objective is to maximize the profit. Under various return quantities, we discuss the effect of product return rate, product disassembly rate and component remanufacturing rate on profit.

In recent years the problems of resource depletion and waste generation have become more and more serious. As a result, countries around the world have begun to take environmental topics, such as reverse logistics and recycling, reuse and remanufacturing of products more seriously. Reverse logistics allows for the end-user to recycle obsolete products. The demand for customization is gradually increasing though recycled components cannot yet meet customer demands for new products. To fulfill a particular customer demand, lots of new materials and recoverable components must be mixed into the production process in order to minimize total production costs and total lead time. The lot-sizing production-to-order problem requires determining the optimal lot-size for the purchase and production of the required materials. This work focuses on the relationships among new materials and recycled components with a specific purchase/production cost, machine yield and capacity, as well as lead time. Using the fuzzy multi-objective linear programming (FMOLP) model, this work develops models for dealing with the relative cost-effectiveness and lead time, among different factors. The proposed model evaluates cost-effectiveness and lead time, while integrating multi-products, multi-suppliers, multi-components, joint components and multi-machines for a remanufacturing production system. Analytical results presented in this work can help decision-making managers to better understand the systematic analysis, potential for cost-effectiveness and lead time of recoverable remanufacturing planning.

This paper presents a dynamic stochastic optimization model to jointly determine marketing and operations decisions in a remanufacturing system. In the system, two remanufactured products share a common recycled core component. One remanufactured product is for the high end market and the other is for the low end market. The company has to decide how many common core components to recycle, how many high end and low end products to remanufacture, and how many high end and low end products to sell in each period given the market conditions. The main source of the uncertainty is the number of the common recycled core component available in each period. The inter-dependence among decision variables and the uncertainty make this problem extremely complicated. Without proper control policies, the company will result in significantly lower profits. Sequential decision processes are used to formulate the problem. The objective is to maximize the sum of total profits over the planning horizon. Efficient value iteration algorithm is developed to solve the problem. The stationary solutions provide relationships between values of decision variables and inventory levels. The impact of the uncertainty is also discussed.

AbstractProduct eco-design includes several methodologies aimed at supporting companies in the development of sustainable products. Currently, this theme is assuming an important role in both the academia and industry worlds due to the increasing attention to environmental problems and the need for a transition toward circular economy business/organizational models. In this context, the present paper focuses on the industrial sector of espresso coffee machines manufacturing which has several unexploited potentialities. The analysis of the sector specificity (internal and external contexts), as well as of the product lifecycle allowed to define an eco-design framework to guide companies involved in the design and production of espresso coffee machines. Effective eco-design strategies should include the combined use of specific methods, tools and metrics to manage all the most important lifecycle phases (beginning of life, middle of life, end of life) during the design activities in order to set preventive actions that avoid future potential environmental impacts. Only in this way, the environmental and economic benefits of the circular economy paradigm (e.g. remanufacturing/reuse of selected components) can be practically exploited in real industrial contexts. The presented case studies confirmed that the application of design for disassembly rules positively contributes to increase the product performances during maintenance and end of life, while a re-design oriented to component modularity could be a key strategy to pursue remanufacturing for boilers, a key and expensive component included in espresso coffee machines.

AbstractFor the reuse of components and structures made of fiber composite materials, a complete remanufacturing process chain is necessary to prepare the parts for a further life cycle. The first step is to dismantle the parts to be reused. Fiber composite components are mostly joined using adhesive technology, so that solution techniques are required for adhesive connections. One possibility is the separation of the adhesive layer by means of thermally expanding particles. Adhesive residues are removed by laser so that the components can be glued again after reprocessing. The decisive factor for which process is used for the remanufacturing of the components is the state at the end of the life cycle. Non-destructive testing methods offer a very good option for detecting damage, planning necessary repairs and direct reuse of damage-free components. Repairs to fiber composite structures have been carried out in aviation for a long time and are accordingly established. These processes can be transferred to the repair of automotive fiber composite components. Many technical solutions were developed and tested as part of the project. Future research work is aimed at further development, particularly with regard to the automation of the technologies in order to enable an industrial application of the recycling of automobile components made of fiber composites.

AbstractAmong the different circular strategies, remanufacturing proves to be particularly interesting since it aims to maintain the value of building components overtime extending their lifespan by guaranteeing multiple consequent cycles of use, overcoming in this way the most common down-cycling logics. However, unlike other industrial fields which already benefit from remanufacturing, the construction sector delays to adopt this practice due to barriers of different nature, namely organizational, information, technical, regulatory and economic. Among these barriers, the first two can now be addressed more effectively thanks to the support of Information and Communication Technologies. The latter offer the possibility of real-time monitoring, remote communication and scenario modeling, opening up to innovative solutions for remanufacturing. Hence, the paper aims to investigate how the application of ICTs can support the cognitive and organizational processes related to remanufacturing of building components. In particular, the paper explores the application of sensing technologies, digital twins and information platforms and assess their potential to support the implementation of circular service-based remanufacturing models in the construction sector.

AbstractAlthough production planning in remanufacturing systems has attracted great interest from the research community, only a couple of real industrial applications can be perceived. Additionally, in real cases, companies are faced with manufacturing multiple products, which further complicates remanufacturing production planning (RPP). Therefore, there is a need to optimise RPP where manufacturers are involved in remanufacturing multiple products. Also optimized systems should consist of a number of uncertainties, such as the uncertain quality of the returned products.Because of these uncertainties the manufacturers have to use new parts or components - with both higher environmental impacts, as well as costs. In the present paper a line balancing scheduler of a remanufacturing system is presented - focusing on the disassembly, machining and reassembly of parts. The objective of the paper is the reduction of usage of the energy and cost intensive new parts with production scheduling using a genetic algorithm (GA). The achievements are illustrated and presented with a real industrial use case from a gas engine producer. A discrete event simulation (DES) is used for evaluation purposes and the results from the scheduler are compared with benchmarks of the current production planning of the gas engine manufacturer.

Product take-back and remanufacturing systems are difficult to implement cost-effectively. Two contributing factors to this problem are the complex nature of the interrelationships among components, and their high degree of variability. Legislated take-back mandates have made it imperative for manufacturers to realize when there is value to be recovered in components and when there is not. This paper proposes a component criticality method to help ascertain this remaining value. We also develop a metric that measures the randomness or variability that a reuse alternative imposes on the remanufacturing system. A case study on washing machines illustrates how the two measures can be incorporated into a design decision model, can help reduce the complexity of reuse operations, and result in a superior design solution.

Remanufacturing is a process that restores old products to perform like new, while saving energy, reducing consumption of natural resources, and lowering environmental emissions. By extending the product life cycle, remanufacturing approaches enable closed loop material cycles that are ultimately necessary for a sustainable society. This paper provides some description of the current automotive remanufacturing enterprise, with a particular emphasis on key vehicle components that are currently remanufactured. The analysis yields two major conclusions. First, market price of a remanufactured component in the automotive sector is surprisingly uncorrelated with the number of companies engaged in remanufacturing that component — at least for companies registered with the Automotive Parts Remanufacturing Association (ARPA). Second, and less surprisingly, we find that remanufacturing reduces environmental burden significantly over new production. This improvement, for the case of the alternator used as a case study, can easily exceed one order of magnitude in the categories of material use, energy consumption, and greenhouse gas (GHG) emissions that are considered here.

The remanufacturing industry is rapidly becoming a source of economic growth and environmental benefit. In the past, researchers have presented cost and energy savings due to remanufacturing a variety of products, largely based on the results of industry-wide surveys. However, little or no effort has focused on the life cycle assessment of remanufacturing. In fact, no study has performed a life cycle assessment of engine components, comparing the original component manufacture with remanufactured components. In this paper, a comparison of the original manufacture and remanufacture of components from a typical Caterpillar diesel engine is described. The “gate-to-gate” analysis considers components that represent a majority of the engine assembly by weight. The comparison is made in two measures of environmental performance: energy and material usage.

Abstract Engineering design problems often have open-ended requirements, especially in the early stages of development. Set-based design is a paradigm for exploring, and keeping under consideration, several alternatives so that commitment to a single design can be delayed until requirements are settled. In addition, requirements may change over the lifetime of a component or a system. Novel manufacturing technologies enable designs to be remanufactured to meet changed requirements. By considering this capability during the set-based design optimization process, solutions can be scaled to meet evolving requirements and customer specifications even after commitment. Such an ability can also support a circular economy paradigm based on the return of used or discarded components and systems to working condition. We propose a set-based design methodology to obtain scalable optimal solutions that can satisfy changing requirements through remanufacturing. We first use design optimization and surrogate modeling to obtain parametric optimal designs. This set of parametric optimal designs is then reduced to scalable optimal designs by observing a set of transition rules for the manufacturing process used (additive or subtractive). The methodology is demonstrated by means of a structural aeroengine component that is remanufactured by direct energy deposition of a stiffener to meet higher loading requirements.

Abstract Design for Remanufacturing (DfRem) is an attractive approach for sustainable product development. Evaluation of DfRem strategies, from both economic and environmental perspectives, at an early design stage can allow the designers to make informed decisions when choosing the best design option. Studying the long-term implications of a particular design scenario requires quantifying the benefits of remanufacturing for multiple life cycles while considering the reliability of the product. In addition to comparing designs on a one-to-one basis, we find that including reliability provides a different insight into comparing design strategies. We present a reliability-informed cost and energy analysis framework that accounts for product reliability for multiple remanufacturing cycles within a certain warranty policy. The variation of reuse rate over successive remanufacturing cycles is formulated using a branched power-law model which provides probabilistic scenarios of reusing or replacing with new units. To demonstrate the utility of this framework, we use the case study of a hydraulic manifold, which is a component of a transmission used in some agricultural equipment, and use real-world field reliability data to quantify the transmission’s reliability. Three design improvement changes are proposed for the manifold and we quantify the costs and energy consumption associated with each of the design changes for multiple remanufacturing cycles.

Abstract Electronic manufacturing of circuit boards has undergone major changes in the last decade as new technologies have emerged and are perfected to replace older ones. A result of the increased board layout densities and higher levels of integration at the chip level is a dramatic increase in the value of circuit boards. The benefit is much more functionality in smaller boards, but the disadvantage is significant losses when a defective board must be scrapped. The same technology that has increased the density of the board functionality has made manual rework to correct manufacturing defects almost impossible. Higher levels of circuit integration in moving from VLSI to ULSI (Ultra Large Scale Integration) have required more pin-outs on the packages which in turn has resulted in finer lead pitches and a change from through-hole mounting to surface mounting technology (SMT). These two changes, with the decreased interchip spacing, have necessitated the use of automation to perform reliable component replacement on defective boards. This paper discusses the complexities of integrating several automation technologies into a single robotic electronic remanufacturing workcell. Involved are vision guidance, control software development, and multiple special end-effector designs for the several required steps, including defective component removal, board cleaning, solder paste dispensing, component placement, and laser soldering [1].

Abstract Remanufacturing is a crucial component for our societies to move toward a circular economy. Compared to new manufacturing, the distinctive nature of remanufacturing is found to have high variability, high uncertainty and, thereby, complexity. Therefore, remanufacturers need to enhance their ability to adjust their systems flexibly. Especially, the ability to reconfigure the production planning and control is crucial for reacting to the high variability and uncertainty. However, few practical methods to do that are available so far. Therefore, to solve this problem, this paper aims to propose a method for designing processes of production planning and control in remanufacturing based on the concept of loosely coupled systems. In the proposed method, Design Structure Matrix (DSM) is applied to identify loosely coupled subsystems that enable to localize impacts of changes within themselves. These subsystems are also utilized to appropriately determine leverage points, as well as allocate human resource. Through the application to a real case of remanufacturing, the proposed method was found to be effective for reconfiguring teams and processes for production planning and control depending on given uncertainties, as well as performing production planning and control activities efficiently.
