Book excerpt: The extraction of virgin materials from nature depletes existing resources and creates huge waste problems both in the extraction process itself and at the product's end-of-life. There is a propensity for this waste to be reduced by adopting an effective product-recovery process, which can ensure that future consumption needs are met for the ever-growing population and eventually result in low rates of landfill. A closed-loop supply chain (CLSC) system provides an efficient sustainable production process where the most used products, parts, and other waste materials are recovered to improve material efficiency and ultimately reduce environmental degradation. Over the last few decades, companies have started to advance in their efforts to implement CLSC systems that contribute to value creation and reduce waste. The objective of this thesis is to map and assess the performance of different product-recovery choices (remanufacturing, recycling, and hybrid) in reducing environmental risks and enhancing the end-of-life of used products, parts, and other waste materials. While the concept of CLSC has been adopted by many companies, there remains a lack of knowledge as to how to identify the criteria with which to evaluate what factors are crucial in adopting different product-recovery choices. Therefore, to learn how to close this knowledge gap, a systematic review of the extant literature surrounding three different product-recovery choices (remanufacturing, recycling, and hybrid) was conducted through the lens of transaction cost economics (TCE). Previous studies have provided information by choosing a specific product-recovery option or choosing between different product-recovery options at a given point in time from the companies' perspectives. This thesis expands upon the critical literature surrounding different product-recovery choices by identifying patterns across industries. Also, this study ascertains the impacts of take-back legislation across industries and across geographical locations with respect to these different product-recovery choices. The results of this study identify distinct characteristics of product-recovery choices and posit how companies might weigh the benefits of remanufacturing and recycling through the integration of CLSC. The findings imply that all relevant intra- and inter-organizational production processes must be channelled to improve the effectiveness and efficiency of CLSC. This thesis contributes to the existing CLSC literature, and fills an important literature gap by exploring industrial patterns with respect to different product-recovery choices; it also highlights important implications for companies seeking to drive their production activities towards being more sustainable.

This book was released on 2024-04-29 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remanufacturing is an industrial process in which a core – a used, discarded, or broken product – is transformed into a product with a like-new specification and condition. However, to this date, remanufacturing activities on the market are few compared to manufacturing. There are several types of remanufacturers; the least common type is the original equipment remanufacturer, an original equipment manufacturer that not only manufactures new products but also remanufactures cores of its own products. Remanufacturing is potentially becoming a more widely used industrial process for original equipment manufacturers, and increased remanufacturing activities can positively contribute to the environment. The contribution comes from a reduction of raw material and energy consumption compared to manufacturing. Therefore, remanufacturing has the potential to decouple environmental impact from economic growth, thus contributing to more sustainable societies. However, assessing the benefits of remanufacturing does not directly correlate to growth within the remanufacturing industry. To encapsulate the environmental, social, and economic benefits of remanufacturing, manufacturers need to be aware of how remanufacturing can be initiated and implemented in practice. Therefore, the objective of this dissertation is to develop support measures for original equipment manufacturers to initiate profitable remanufacturing. This research takes a stand in case study and transdisciplinary research where the initiation of profitable remanufacturing is studied at two original equipment manufacturers. The research study developed knowledge of how remanufacturing could be incorporated into existing operations at original equipment manufacturers. In parallel, financial assessments based on cost-benefit analysis were built to measure how well the case companies could perform remanufacturing. For the case study research, seven remanufacturing scenarios were developed, ranging from centralised remanufacturing performed by the original equipment manufacturer to decentralised performed at multiple locations using a retail network. Which scenario is preferable depends on, for example, risk-consciousness, cooperation between actors, and volume targets. However, given ideal circumstances, remanufacturing in-house in a centralised scenario was shown to be the most beneficial for the investigated original equipment manufacturer since the fewer middle hands and economies of scale also potentially enable lower costs. For the transdisciplinary research, the remanufacturing initiation was business model-centric, meaning that the remanufacturing system was a consequence of a decision for a specific business model. Here, a scenario-based analysis was developed to understand under which circumstances the business model with remanufacturing was more lucrative for the provider – the original equipment manufacturer – and less costly for the users – the customers. For this, a systematic assessment approach was developed consisting of three steps: (1) provide a cost overview for each business model, (2) create scenarios by modifying the cost drivers, and (3) combine scenarios to reach synergetic effects. Based on the case study, two sets of four prerequisites for initiating remanufacturing were derived. These are divided into essential and supporting prerequisites and illustrated through a framework called the Remanufacturing Rocket. The essential prerequisites highlight fundamental requirements to perform remanufacturing. Should one of these four factors be missing, remanufacturing cannot be successfully initiated. The supporting prerequisites are valuable to enhance the effectiveness and efficiency of the process, such as through streamlined operations, organisational change, or information exchange. Hence, to reach the fullest potential of remanufacturing, both the essential and the supporting prerequisites are needed. Furthermore, the area of financial assessments was explored in a systematic literature review to identify insights for developing such assessments tailored for individual original equipment manufacturers in initiating remanufacturing. For this, six perspectives for framing financial assessments are proposed. These cover the system boundaries for the assessments as well as the individual needs and visions of original equipment manufacturers. Additionally, a framework was developed to select financial assessment models for remanufacturing initiations based on ease of use and capability to handle complex datasets. Conclusively, it is proposed to apply the prerequisites for initiating remanufacturing together with a financial assessment in an iterative manner to investigate the profitability for original equipment manufacturers to initiate remanufacturing. The essential prerequisites influence the first iteration of the financial assessment, which then contributes to refinements of how the essential prerequisites should be aligned in an economically preferable way. Once satisfactory, another iterative process could be initiated between the supporting prerequisites and the financial assessment. By using the proposed approach, the prospects of profitable remanufacturing could be thoroughly investigated before attempting to initiate a process in practice, thus reducing the number of resources spent in vain. Additionally, the iterative process was integrated into a 5-step Approach For Initiating Remanufacturing (5AFIR) to guide original equipment manufacturers towards initiating profitable remanufacturing. Refabrikation (oder Wiederaufbereitung, engl. Remanufacturing) ist ein industrieller Prozess, bei dem ein Altteil – ein gebrauchtes, ausrangiertes, verschlissenes oder defektes Produkt – gemäß den Herstellerspezifikationen in einen neuwertigen Zustand gebracht wird. Heutzutage macht Refabrikation allerdings nur einen kleinen Teil der Fertigungsindustrie aus. Verschiedene Arten von Unternehmen betreiben Refabrikation, wobei Originalgerätehersteller, sogenannte OEMs (engl. für Original Equipment Manufacturer), am seltensten sind. Solche OEMs betreiben neben Produktion auch eine Wiederaufbereitung ihrer eigenen Produkte. Refabrikation kann sowohl ökologische als auch ökonomische Vorteile bringen und hat somit grundsätzlich hohes Marktpotential. Der geringere Rohstoff- und Energieverbrauch von Refabrikation im Vergleich zu Neuproduktion ist ein Beispiel für ökologischen Vorteil. Refabrikation ermöglicht außerdem, negative Umweltauswirkungen durch Produktion und Wirtschaftswachstum voneinander unabhängig zu machen und trägt somit zu nachhaltigem Wachstum bei. Allerdings hängt der Nutzen von Refabrikation nicht direkt mit dem Wachstum innerhalb der Refabrikationsbranche zusammen. Um die ökologischen, sozialen und ökonomischen Vorteile nutzen zu können, müssen Hersteller Kompetenz zur praktischen Umsetzung von Refabrikation aufbauen. Ziel dieser Dissertation ist daher die Entwicklung von Unterstützungsmaßnahmen und -konzepten für OEMs, die zu profitabler Refabrikation führen. Diese Arbeit basiert auf einer Fallstudie und auf transdisziplinärer Forschung, bei der die Einführung von profitabler Refabrikation bei zwei OEMs untersucht wurde. Die Fallstudie lieferte Erkenntnisse darüber, wie Refabrikation in bestehende Abläufe bei OEMs integriert werden kann. Außerdem wurden finanzielle Bewertungskriterien auf der Grundlage einer Kosten-Nutzen-Analyse erstellt, um messen zu können, wie erfolgreich die untersuchten Unternehmen Refabrikation implementieren könnten. Für die Fallstudie wurden sieben Refabrikationsszenarien entwickelt, die von zentraler Refabrikation durch das OEM bis zu dezentraler Refabrikation an mehreren Standorten durch ein Netzwerk von Niederlassungen reichen. Welches der Szenarien vorzuziehen ist, hängt beispielsweise vom Risikobewusstsein, der Zusammenarbeit der Akteure und den angestrebten Stückzahlen ab. Unter idealen Umständen erwies sich die unternehmensinterne Refabrikation mit zentralisierter Struktur als das vorteilhafteste Szenario. Für die untersuchten OEMs führten weniger Zwischenhändler und Größenvorteile zu geringeren Kosten. In der transdisziplinären Forschung dieser Dissertation wurde davon ausgegangen, dass das Refabrikationssystem aus der Entscheidung für ein bestimmtes Geschäftsmodell folgt. Basierend auf verschiedenen Szenarien wurde analysiert, unter welchen Umständen das Geschäftsmodell inklusive Refabrikation für den Anbieter (OEM) lukrativer und für die Anwender (Kunden) kostengünstiger war. Hierzu wurde ein systematisches Bewertungsschema entwickelt, das aus drei Schritten besteht: (1) Bereitstellung einer Kostenübersicht für jedes Geschäftsmodell, (2) Erstellung von Szenarien durch Modifikation der Kostentreiber und (3) Kombination von Szenarien, um Synergieeffekte zu erzielen. Anforderungen für die Einführung von Refabrikation wurden auf Basis der Fallstudie abgeleitet. Diese sind in vier essentielle und vier unterstützende Anforderungen eingeteilt und werden durch ein Modell namens Refabrikationsrakete veranschaulicht. Die essentiellen Anforderungen sind grundlegend für die Durchführung von Refabrikation. Ist eine dieser vier Anforderungen nicht erfüllt, kann Refabrikation nicht erfolgreich umgesetzt werden. Die unterstützenden Anforderungen steigern die Effektivität und Effizienz des Einführungsprozesses, beispielsweise durch optimierte Abläufe, organisatorische Änderungen oder Informationsaustausch. Um das volle Potenzial von Refabrikation auszuschöpfen, müssen sowohl die essentiellen als auch die unterstützenden Anforderungen erfüllt werden. Wirtschaftliche Bewertungskriterien wurden im Rahmen einer systematischen Literaturrecherche betrachtet. Ziel der Recherche war es, Erkenntnisse für die Entwicklung solcher Bewertungskriterien zu erlangen. Die Kriterien sollen dabei auf einzelne OEMs und die Einführung von Refabrikation zugeschnitten sein. In dieser Arbeit werden sechs Ansätze für die Entwicklung wirtschaftlicher Bewertungskriterien vorgeschlagen. Diese Ansätze behandeln sowohl Systemgrenzen für die Bewertungskriterien als auch individuelle Bedürfnisse und Ziele der OEM. Darüber hinaus wurde ein Rahmenwerk entwickelt, um wirtschaftliche Bewertungskriterien auf Basis ihrer Benutzerfreundlichkeit und ihrer Fähigkeit zur Bewältigung komplexer Datenmengen auszuwählen. Abschließend wird vorgeschlagen, die Anforderungen für die Einführung von Refabrikation zusammen mit einer wirtschaftlichen Bewertung iterativ zu prüfen, um die Rentabilität von Refabrikation für OEMs zu analysieren. Die essentiellen Anforderungen beeinflussen die erste Iterationsschleife der wirtschaftlichen Bewertung. In dieser ersten Schleife wird verfeinert, wie die Grundanforderungen wirtschaftlich sinnvoll kombiniert werden können. Es folgt eine zweite Iterationsschleife zwischen den unterstützenden Anforderungen und der finanziellen Bewertung. Mit diesem Vorgehen kann das Potential einer rentablen Refabrikation gründlich untersucht werden bevor mit der Realisierung begonnen wird. Dadurch können eventuell erfolglose Einführungsversuche vermieden und vergeblich aufgewendete Ressourcen reduziert werden. Der iterative Prozess wurde in einen 5-stufigen Modell zur Einführung von Refabrikation (5AFIR) zusammengefasst. Återtillverkning är en industriell process där en stomme – en använd, uttjänt eller trasig produkt – omformas till en produkt vars specifikation och kvalitet motsvarar nyskick. Idag utgör återtillverkning endast en liten del av den totala tillverkningsindustrin. Det finns flera typer av återtillverkare; den ovanligaste är originaltillverkande återtillverkare, det vill säga, ett tillverkande företag som även återtillverkar sina egna produkter. Genom den låga grad av återtillverkning bland originaltillverkare idag finns det utrymme för att verka för en ökning. En sådan ökning kan bidra till miljömässiga fördelar genom att mängden råmaterial och energi reduceras jämfört med nytillverkning. Det finns därför en möjlighet för återtillverkning att bidra till en frikoppling av miljömässig påverkan från ekonomisk tillväxt, vilket i sin tur bidrar till ett mer hållbart samhälle. Fast att endast värdera nyttan av återtillverkning leder inte direkt till en tillväxt inom återtillverkningsindustrin. För att omfamna de miljömässiga, sociala och ekonomiska nyttor som återtillverkning kan bidra med måste originaltillverkare vara medvetna om hur återtillverkning kan initieras och implementeras i praktiken på ett ekonomiskt lönsamt sätt. Denna doktorsavhandlings syfte är därför att utveckla stöd för originaltillverkare att initiera lönsam återtillverkning. Forskningen utgår från en fallstudie och transdisciplinär forskningsmetodik där initieringen av lönsam återtillverkning studeras vid två originaltillverkare. Den utförda forskningen utvecklade kunskap om hur återtillverkning kan integrerats i en originaltillverkares befintliga verksamhet. Parallellt med detta utvecklades ekonomiska utvärderingsmetoder för att tillhandahålla ett mått på hur väl fallföretagen skulle kunna utföra återtillverkning. För fallstudien utvecklades det sju återtillverkningsscenarion som sträcker sig från centraliserad återtillverkning, som utförs av originaltillverkaren, till decentraliserad, som utförs vid flertalet platser inom ett återförsäljarnätverk. Vilket scenario som var mest fördelaktigt berodde exempelvis på riskmedvetenhet, samarbete mellan aktörer, och tillverkningsvolym. Men givet ideala förhållanden visades det att centraliserad återtillverkning vore potentiellt mest fördelaktigt för fallföretaget, eftersom färre mellanhänder och stordriftsfördelar möjliggör lägre kostnader. För det andra fallföretagets initieringen av återtillverkning vid tillämpning av den transdisciplinära forskningsmetodiken var det ett affärsmodellsfokus, vilket innebar att återtillverkningssystemet var en konsekvens av ett beslut för en viss affärsmodell. I denna del av forskningen utvecklades en scenariobaserad analysmetod för att förstå under vilka förhållanden som affärsmodellen tillsammans med återtillverkning vore mer lukrativt för företaget – originaltillverkaren – och mindre kostsamt för användaren – kunden. För detta utvecklades en systematisk ansats för ekonomiska utvärderingar bestående av tre steg: (1) tillhandahåll en kostnadsöverblick för varje affärsmodell, (2) skapa scenarion genom att modifiera kostnadsdrivarna, och (3) kombinera scenarion för att uppnå synergieffekter. Med utgångspunkt i fallstudien utvecklades även faktorer för att forma krav för hur originaltillverkare kan initiera återtillverkning. Dessa faktorer delas upp i grundläggande och stödjande kravställningar, och de bygger tillsammans upp ett ramverk benämnt Återtillverkningsraketen. De grundläggande kravställningarna lyfter fram elementära krav vid utförandet av återtillverkning och om en av de fyra skulle saknas kan återtillverkning inte utföras på ett framgångsrikt sätt. De stödjande kravställningarna är av värde för att förbättra återtillverkningseffektiviteten genom exempelvis bekymmersfritt utförande av processer, organisationsförändringar, eller informationsutbyten. Därigenom, för att nå den fulla potentialen av återtillverkning, behövs både de grundläggande och de stödjande kravställningarna. Dessutom utforskades området för ekonomiska utvärderingsmetoder i en systematisk litteraturgenomgång för att identifiera insikter för att utveckla sådana metoder skräddarsydda för individuella originaltillverkare som initierar återtillverkning. För ändamålet föreslås sex perspektiv för att forma ekonomiska utvärderingsmetoder. Dessa täcker såväl systemgränserna för utvärderingarna som individuella behov och visioner hos originaltillverkare. För att vidare stödja företagen utvecklades ett ramverk för att välja ekonomiska utvärderingsmetoder för initieringar av återtillverkning baserat på användarvänlighet och förmåga att hantera komplexa datamängder. Slutligen föreslås det att tillämpa de framtagna kravställningarna tillsammans med ekonomisk utvärdering genom att iterativt undersöka möjligheterna för hur återtillverkning kan initieras för originaltillverkare. De grundläggande kravställningarna influerar upplägget för den första iterationen av den ekonomiska utvärderingen, vilken i sin tur nyttjas för att förfina hur de grundläggande kravställningarna kan läggas samman på ett ekonomiskt fördelaktigt sätt. När en godtagbar nivå uppnåtts kan ytterligare en iterativ process utföras mellan de stödjande kravställningarna och den ekonomiska värderingen. Genom att tillämpa det föreslagna tillvägagångssättet kan möjligheterna för återtillverkning undersökas på en detaljerad nivå innan initieringsförsök i praktiken, och såldes kan mängden slösade resurser minskas. Utöver detta integrerades det iterativa tillvägagångssättet med en 5-stegsansats för initiering av återtillverkning (5AFIR).

Available in PDF, EPUB and Kindle. Book excerpt: Supply Chain Network design is an important strategic decision that helps Original Equipment Manufacturers (OEMs) to position their supply chains for profitable reverse supply chains. We observe that between the competitors of technology products, companies such as HP and Xerox (printers) and Apple and Google (smartphones), one competitor (HP and Apple) manages the reverse supply chain to extract value in a profitable manner, while the other competitor (Xerox and Google) uses a third-party reverse logistics company to simply recycle consumer returns. In the literature, supply chain levers, such as consumer Willingness to Pay (WTP) for remanufactured products, managing the collection process of consumer returns, the quality of the consumer returns and the design of reverse logistics have been identified as key factors influencing OEM participation in reverse supply chain. In this thesis, we show that, under the same supply chain levers mentioned above, the OEMs approach to supply chain network design can significantly impact the profitability in the reverse supply chain over the product lifecycle. To address the supply chain network design problem for an OEM, we propose an integrated multi-period optimization model called Product Life Cycle Optimization Model (PLCOM), to design the Closed Loop Supply Chain (CLSC) for the OEMs. The PLCOM is a Mixed Integer Linear Program that consists of a Demand model and a Pricing model. The Pricing model determines the optimal production quantity and the selling price computed over the product life cycle, based on a realistic customer Willingness to Pay (WTP) for new and remanufactured products. The Demand model computes the demand for new and remanufactured products based on the Extended-Basss diffusion model. The PLCOM also computes the cannibalization of new product sales due to the introduction of remanufactured product and the availability of product returns for remanufacturing, constrained by the collection of the returns. The Demand and Pricing models are then integrated into a Mixed Integer Program (MIP) model to design the CLSC network.The PLCOM is applied to a realistic case study using Apples iPhone 7 for a product life cycle of 8 years. The final MIP model has 30 binary variables, 48066 continuous variables and 3972 constraints and was solved using CPlex in 0.1619 seconds. We show that an integrated approach to design the supply chain network by the OEMs is more profitable compared to a sequential approach, where the OEM initially designs the optimal forward supply chain network and implements it. Later, when the OEM decides to participate in the remanufactured market, the OEM revisits the network design to obtain the optimal CLSC for the reverse supply chain. Using sensitivity analysis, we also show that slow diffusing products are more profitable for remanufacturing and fast diffusing products require flexibility in capacity planning, in order to avoid the fixed cost of opening additional facilities. In the case of fast diffusing products, we also observe a delayed surge in demand for remanufactured products caused by a delayed cannibalization effect on new product demand. Finally, a sensitivity analysis on the quality of the consumer returns gives an upper bound on the investment that can be made by the OEM in incentivizing the consumers to improve the quality of the returns.In the technology industry, frequent new product releases entail OEMs to concurrently manage successive generations of products. For example, Apple currently sells multigeneration iPhones, such as iPhone 6S, iPhone 7, iPhone 8 and iPhone X. Hence, we extend the integrated model to a two-generation product setting. We model the demand for the second-generation product as a substitution for the first-generation product. We identify the \textit{logit} function as the substitution function to compute demand for the second-generation product and validate total sales using the iPhone4 and iPhone 4S sales data. The extended PLCOM is again used in a realistic case study based on the consumer WTP for iPhone 7 and iPhone 8 as the successive generations of products. The extended PLCOM has 30 binary variables, 77474 continuous variables and 6470 constraints and the optimization problem was solved using CPlex and the solver took 46 seconds to solve the problem. Finally, we conduct a sensitivity analysis to determine the most profitable time to introduce the second-generation product, characterize the slow and the fast diffusing products in the two-generation product setting and analyze the impact of the quality of consumer returns on the profit.

Available in PDF, EPUB and Kindle. Book excerpt: Closed-loop supply chains (CLSCs) that integrate the activities for reclaiming residual values in postconsumer products with the traditional forward supply chain activities are important from financial and environmental perspectives. This thesis develops models and analyses on three topics novel to the field of CLSC research with a goal of advancing knowledge about effective decision-makings in CLSCs. In the first part of the thesis, we study joint control of stochastic forward and stochastic reverse material flows in CLSCs. With an application to a CLSC where postconsumer products are collected for warranty service purposes, we demonstrate that the benefit of coordinating two production activities could be significant. We develop a model that can be used to obtain an effective inventory control policy for coordinating forward and reverse material flows. Through Monte Carlo simulation and global sensitivity analysis, we identify major influential factors that affect system's warranty cost savings performance. The results indicate that joint control of forward and reverse material flows greatly improves warranty cost savings performance as well as system's robustness to uncertainties. The second part of the thesis develops a differential game model for characterizing decentralized time-varying competitive decision-making in a CLSC. The differential game model is particularly useful for studying time-varying interactive decision-making in CLSCs that involve many stakeholders who pursue different objectives in forward and reverse production activities. We identify optimal prices and production strategies that evolve over time under fluctuating market demand. Also, the model provides a quantitative scheme that can be used to obtain an efficient apportionment of product recovery processes. The third part of the thesis describes the relationship among consumers' risk-aversion, product cannibalization of new products by remanufactured products, and growth of CLSCs through price optimization models. Whereas price is one of the most effective variables for managing market demand, previous CLSC research has mainly focused on operational problems without paying much attention on the interface between CLSCs and markets. We develop models that jointly determine optimal prices in forward and reverse channels considering consumers' willingness-to-pay (WTP) for remanufactured products, consumers' willingness-to-accept (WTA) for a buyback price, and consumers' risk aversion to uncertain quality perceptions. The results show that consumers' active participation in CLSC is an important factor for the viability and growth of a CLSC. Also, we show that companies can benefit from product remanufacturing although it may be accompanied by production cannibalization.

Book excerpt: Supply chain management has evolved over the course of history in order to provide faster and efficient service to those companies that follow its principles. As there have been advances in technology and changes in the way business is conducted across the globe, supply chains also have had to change in order to remain effective. With greater attention paid to resource depletion, environmental impact, and waste reduction; the concept of closed-loop supply chains has garnered the attention of managers who look to make their production processes more efficient. Finding ways to judge the performance of these supply chains is critical to managers. By identifying key performance measures, they are able to gauge how their closed-loop process is performing as well as identify areas for improvement.

Book excerpt: In 2016, Japan proposed “Society 5.0”, a concept in which innovation and technology are used to solve social problems. The core elements of Society 5.0 include problem-solving and value creation, interdisciplinary skills, diverse opportunities, resilience, and environmental harmony. This concept also highlights the United Nations' 17 Sustainable Development Goals (SDGs), which all individuals and organizations need to face. The promotion of the SDGs from a psychological perspective is believed to be beneficial and aligns with the intention of the United Nations. Sustainable Development Goals (SDGs) can be examined from a microscopic level to understand individuals' mental processes and attitudes toward them. Investigating the relationships between the SDGs and social and positive psychology can benefit their promotion. Discussing the SDGs from a psychological perspective aligns with the intention of the United Nations.
