Für die Perspektive der Textiltechnik stellt das Closed-Loop Product Lifecycle Management einen spannenden Ansatz dar, um durch neuartige Technologien in der Datenerfassung und -verwertung sowie der durchgängigen Informationssteuerung die Herausforderungen einer stärkeren Kundenorientierung und einer höheren Nachhaltigkeit in der gesamten Wertschöpfungskette zu bewältigen. Dabei schafft das PLM in Unternehmensnetzwerken eine Plattform für die Effizienz- und Qualitätssteigerung in der Produktion sowie der Entwicklung von Dienstleistungen und Produkten, in die die Erfahrungen aus vorherigen Produktlebenszyklen unmittelbar einfließen. Durch die besonderen Anforderungen der Textilbranche hinsichtlich einer breiten Produktvariation, einer aufwendigen Nachverfolgung einzelner Produkte und der hochfragmentierten Produktionsprozesse adaptieren Textilunternehmen entsprechende Lösungen erst langsam. Jedoch erkennen immer mehr Organisationen die Vorteile einer individuellen PLM-Lösung. Forschungsinstitute wie das ITA unterstützen durch vielfältige Forschungsvorhaben diese Entwicklung, um gemeinsam mit den Partnern aus der Industrie die Flexibilität und Transparenz durch PLM für eine stärkere Wettbewerbsfähigkeit der Textiltechnik der Zukunft nutzbar zu machen [9, 10, 13].

Full textAbstract:
In the current realities, there are practices where companies use various tools and systems to plan and manage the quality of products and processes. Many of these tools and systems are disconnected from data/product information management systems to varying degrees, depending on the level of workflow automation. The disadvantage of disparate quality management tools is that repetitive issues that occur across multiple systems can make it difficult to investigate root causes by isolating related data items without being able to understand the relationships between them. The conventional method also provides energy loss in production due to extra power consumption. Redundant work to identify and fix quality issues can be done across multiple tools without an automated way to communicate what you've learned to other teams. This leads to inconsistent and incomplete solutions to problems that hinder rather than improve product and process quality. Thanks to the recent development of new technologies, many IT tools have become available on the market, among them product lifecycle management (PLM) systems, which are very popular among companies that allow them to create and support complex industrial products, including aeronautical equipment. The article provides an end-to-end solution on a platform like this, which aims to link quality to product design, sustainable development in the field of energy-effective production. This approach provides multidisciplinary teams and the broader supply chain with powerful closed-loop capabilities to identify and manage risks, improve quality, meet customer requirements, and ensure compliance with environmental health, safety, and information management requirements.

This article discusses the advantages of integrating project portfolio management (PPM) with product lifecycle management (PLM) software for project planning. Many engineering companies are now stepping forward to integrate their PPM and PLM systems for more close-up project planning. By tying the two systems, engineering firms are better able to manage time spent on specific projects, to get an overarching and realistic view of where the project stands, to stay on the schedule and to meet specific goals. The tied systems also allow engineers to get a broad view of the project that extends beyond their engineering piece. In engineering companies, where the project status is inevitably tied to the engineering department, closing the loop between theoretical plans and engineering progress can make for big budgetary savings and offer important insight into product planning. Many engineering companies that do not yet have a PPM system are now considering implementing one to plan their product mixes.

Full textAbstract:
This article discusses various aspects of data and manufacturing innovation. Industry today is rapidly adopting digital thread, a best practice in product data management that emphasizes a closed-loop process in which product lifecycle data is linked and traceable to design intent. The best practices in design and manufacturing stand in stark contrast to data revolutions being fomented in other fields. The data ecosystem is the collective memory of the complete output of a project, from conception to post-production and lifecycle activity for its artefact. It must encompass the dead ends as well as the amazing insights; the unbuilt alternatives and the simulation tests for prototypes; the information arcs traced out in the course of design and manufacturing process; and the consumer reviews and in-service information feeds from devices in the field. Vision of design requires engineers, designers, and manufacturers to reconsider some long-held beliefs about best practices. Computer scientists are developing solutions that might enable this transition; however, enterprises need to commit to underlying processes and cultures that will truly affect change.

Full textAbstract:
The mathematical modeling of reverse logistics inventory systems ignores the fact that returned items may arrive out of sequence, i.e., with different number of remanufacturing times. Moreover, such modeling assumes that the retuned items may retain the same quality upon recovery regardless of how many times they have been previously remanufactured. This paper develops a new mathematical expression of the percentage of retuned items that can be remanufactured a finite number of times. The proposed expression is modeled as a function of the expected number of times an item can be remanufactured in its lifecycle and the number of times an item can be technologically (or optimally) remanufactured based on its quality upon recovery. The model developed in this paper considers joint production and remanufacturing options. The return rate is a varying demand-dependent rate, which is a decision variable with demand, product deterioration, manufacturing, and remanufacturing rates being arbitrary functions of time. The model considers the initial inventory of returned items in the mathematical formulation, which enables decision-makers to adjust all functions and input parameters for subsequent cycles. Illustrative examples indicate that dependent purchasing price of recovery items and the incorporation of remanufacturing investment cost significantly impact the optimal remanufacturing policy.

Contemporary industry is beginning to realize the negative impact that they have on the environment in terms of greenhouse gas emissions, destruction of natural habitats, hazardous waste emissions, etc. This new found consciousness has prompted a second look on part of the manufactures at how modern manufacturing practices can be modified so as to be more environmentally friendly. Environmental impact of manufacturing can be minimized in various ways. In this context, management is often called upon to provide active leadership in managing their facilities so as to minimize their environmental impact. Some examples of such activities include green supply chains and design for disassembly. Such activities help to create a closed loop product lifecycle that is required to reduce the amount of raw material used and the amount of waste created by production. Similarly using design for manufacturability principles aid in the minimization of raw material used and waste generated as well. Also, facilities are starting to move away from reactive approaches to environmental issues. They are now using proactive approaches and value seeking approaches where the environmental issues are dealt with before they are created. This paper presents an overview of environment conscious manufacturing practices that seek to minimize the negative environmental impact of manufacturing. Being a literature review, this paper primarily deals with state of the art in current practice pertaining to green manufacturing.

Abstract: The main cost associated with the Product lifecycle of an Aerospace part is its Manufacturing and Maintenance. There are several Non-conformance (sometimes referred to as defects) reported during part manufacturing, shipment, assembly, field operation, service, and overhaul. These are due to improper handling or due operational wear and tear. Non-conformance is a non-fulfilled requirement to design specification that could be a dimension, specification, or engineering process deviation. In the Aerospace industry Non-conformances not identified or not closed in time can have a cascading business impact across the supply chain and become a key reason of risk to productivity, lead time, and cost. Aerospace Non-conformance needs to be addressed with extreme caution as it could even cost life due to Nonconforming products in operation. These cannot be avoided but they need to be managed with mitigation plans, setting up priorities, planning, project management, and seamless communication between stakeholders [1]. Today, we live in the digital age where all conventional engineering processes are continuously automated and digitized with emerging technologies to maximize productivity and customer satisfaction. Non-conformance execution processes, workflows, and communications are potential areas that could be integrated as a web-based digital solution [2]. The paper would attempt to bring up challenges encountered by the conventional Non-conformance dispositioning processes and workflows and benefits of the Digitized framework. It would also detail all the key features of the Digital solution along with its tangible and intangible benefits to all the stakeholders by integrating workflows and taking productivity to the next level.

Recent studies have advocated that digital technologies (DTs) positively affect the transition of a linear economy model to a circular economy (CE) model and facilitate enterprises in implementing circular strategies. Despite this general statement, the literature still overlooks how enterprises should apply various DTs of Industry 4.0 across the entire product lifecycle to operationalize CE-related strategies. To fill this gap, this paper proposes a conceptual framework exploring DTs in terms of CE operationalization from the perspective of the product lifecycle. Based on insights gained through a systematic literature review, we clarify how DTs can facilitate CE performance objectives through the three stages of the product lifecycle: product design, product use, and product recovery or recycling. Furthermore, we study how various Industry 4.0 DTs, such as the Internet of things, big data, and cloud computing, are utilized to operationalize the transition toward a CE. DTs applied to the service-oriented product-service system contributes innovation into circular business models to make full use of idle resources and provide high-quality personalized services. We have adopted three performance objectives: using fewer materials and resources, extending product lifespan, and closing the loop to evaluate the effects of DTs in promoting CE development. By investigating how DTs affect CE performance objectives, the conceptual framework developed in this paper advances the knowledge regarding the role of DTs as an enabler of CE from the product lifecycle. Our findings provide a practical reference enabling researchers and managers to harness the potential of DTs to support CE transition.

Purpose – Increased economic development in emerging economies has spurred the growth of “fast fashion” and this in turn has led to not only an opportunity for recycling activity but also a need to do so from a sustainability perspective. The purpose of this paper is to consider the emergence of such recycling activity in a developing economy. Design/methodology/approach – A process flow approach guides identification of stakeholders and an analysis of reverse supply chain structure and processes. An adapted and extended theory of planned behaviour (TPB) model is employed to explore recycling behaviour at the household level. Findings – The authors find rather haphazard garment recycling channels in Delhi NCR. In particular product acquisition processes are characterised by poor value appropriation and provide a limited service to households. This is supported by the householder survey that finds poor satisfaction levels with most recycling channels. PLS path modelling tested hypotheses that each of the four constructs (attitudes, subjective norm, perceived control and sense of duty) are significant determinants of “intention to plan to recycle”. Having tested for various possible meditating effects, sense of duty was found to act as a precursor to attitude. In this model all other constructs were significant determinants of intention to recycle garments. Thus the study highlights the role of “sense of duty” in attitude formation, a key determinant of intention to recycle garments. This highlights the importance of adherence to sustainable practices and the need for associated governance and regulation. Subjective norm points to the impact of a range of people, including experts. While perceived control points to difficulties encountered both from a self-efficacy and external (opportunity) perspectives. Practical implications – The findings suggest that reverse supply chain design should address the limitations of the product acquisition process (especially poor value appropriation and limited collection services) and respond to household motivational factors and perceived difficulties. Originality/value – The study considers the impact of the garment product lifecycle on household behaviour. In this context the adapted TPB model addressed the role of conscious planning. The model is extended to include sense of duty, this contributes to emerging work in this field.

Full textAbstract:
The increasing complexity and performance expectations of modern mechanical systems necessitate a more robust approach to design that prioritizes reliability from inception. This paper presents a conceptual framework that integrates Finite Element Analysis (FEA) with Design Failure Mode and Effects Analysis (DFMEA) to achieve a reliability-centered design (RCD) methodology for mechanical components. While FEA enables engineers to predict stress distribution, deformation, and fatigue life under simulated loading conditions, DFMEA offers a structured pathway for identifying potential failure modes, their causes, and mitigation strategies early in the design cycle. The integration of these two techniques ensures that both physical and functional weaknesses are addressed proactively. The proposed framework adopts a closed-loop design validation strategy where insights from FEA are continuously fed into the DFMEA process to enhance the prioritization of risks based on severity, occurrence, and detectability. In turn, DFMEA findings guide design modifications, which are subsequently validated through iterative FEA simulations. This synergistic loop allows for real-time optimization of component geometry, material selection, and load-bearing capacity while systematically reducing failure risks. Key features of the framework include a reliability scoring system, decision-support metrics, and traceability of design changes linked to risk mitigation. Case applications in the automotive and aerospace industries demonstrate the utility of the framework in improving component durability, extending service life, and reducing warranty claims. Additionally, the paper discusses the integration of this framework within Product Lifecycle Management (PLM) systems and the potential for automation using machine learning to predict high-risk regions based on historical data. By bridging the gap between virtual prototyping and risk assessment, this conceptual framework enables a shift from reactive to proactive design strategies. It provides design engineers, quality managers, and product developers with a unified tool to enhance reliability, safety, and cost-effectiveness in mechanical systems development.

The article is dedicated to the analysis of digital certification of aviation equipment on the basis of multifunctional “Siemens PLM Software” (PLM - Product Lifecycle Management) technologies and “Verification Management” solution. In the theoretical part of the article, the authors point out that during certification a project usually goes through two stages: validation and verification. The first stage involves checking the project requirements for correctness and completeness, while the second stage aims to confirm that the designed aircraft is fully consistent with the validated requirements for it. The article states that the implementation of modern systems engineering practices is based on various instrumental components, methodology, and professional competence and is implemented as part of the general PLM strategy of an enterprise using “Siemens Digital Industries Software” products. In the course of the research, the authors of the article came to the conclusion that “Verification Management” solution in the “Teamcenter Siemens PLM Software” system helps enterprises in the aerospace and defence industries to successfully implement projects on creation of innovative products within a given timeframe and budget. “Verification Management” solution forms a closed traceability cycle for all stages of the control process of project decisions aimed to confirm compliance of the design with specified requirements. “Verification Management Catalyst” module accelerates the enterprise’s transition to digital technology; therefore, this transition improves reliability and productivity while lowering the total cost of ownership. “Teamcenter” system supports verification of the implementation of product development programs, reduces the time and cost of project decisions, which ultimately improves the entire work of the enterprise. “Verification Management” solution is a fully functional lifecycle management solution that is able to transmit product requirements and their changes to all participants of the design process.

We present a methodology for systematically using an SPDM platform as the cornerstone of product development. The target is to base product development on clearly defined targets and requirements in different phases of the product development lifecycle. This is achieved by means of a data-centered approach where all data is retained in a digital form in the platform. Instead of reporting, users are provided with different views to the same data. We will demonstrate how a static document-based validation system can be replaced by a common validation data platform. In addition, we aim to base the validation requirements on a reliability analysis workflow.
 In this case, the platform is used not only to handle the simulation data but to encompass the whole product validation scope. To this end, we show how to couple requirements to the simulations and handle all the design decision data together with the simulations and use these to drive the design. In addition, we present ways to replace simulation reports with dynamic dashboards. To complete the loop, we touch the topic of PLM integration as a tool for assuring completeness of validation data in the product lifecycle.
 The motivation for the activity is a dramatic reduction in product development time based on a possibly somewhat longer concept phase but less iterations during the detail design phase. We will also present decision making based on data stored in the platform as well as demonstrate the data-centered approach to validation data. In addition, other benefits such as the re-use of data and simulation workflows along with the automatically handled data management are demonstrated. To conclude, some end user opinions and experiences in adopting a new system will be presented.
 Future developments will include moving also the physical testing data and coupling that with the corresponding simulations and validation requirements.

In a time characterised by increasing environmental apprehensions and the necessity for sustainable progress, the effective utilisation of resources has become a crucial mandate for enterprises, governments, and communities alike. This summary presents a comprehensive examination of the several techniques and practises that are crucial in attaining sustainable materials and energy management. Efficient resource utilisation comprises a wide range of ideas and practises, which include but are not limited to material efficiency, energy conservation, waste reduction, and measures related to the circular economy. This study examines the fundamental elements of these methods, emphasising the significance of resource optimisation and its contribution to the reduction of environmental consequences linked to resource extraction and use. The achievement of efficient resource management is contingent upon the implementation of robust policy frameworks, the exercise of corporate responsibility, and the cultivation of consumer awareness. The significance of lifecycle assessments (LCAs) and the incorporation of eco-design concepts into the process of product creation is underscored in order to mitigate resource consumption and environmental consequences from the very beginning. The adoption of circular economy models, characterised by the conservation, reuse, and recycling of resources within a closed-loop system, holds significant potential for enhancing resource efficiency. In this paper, we elucidate the advantages associated with the adoption of circular economy practises and provide illustrative examples of organisations that have effectively implemented these concepts. In the context of a world with limited resources, organisations that prioritise efficient resource utilisation not only adhere to ethical principles but also gain a strategic edge, enhancing their prospects for long-term viability. These abstract lays the groundwork for further investigation into the diverse tactics and technologies that have the potential to drive us towards a future that is more sustainable and efficient in terms of resource utilisation.

Digital twin technology has become one of the key directions of intelligent manufacturing with a strong relationship to product lifecycle management. It contributes to increasing efficiency and flexibility in solving highly complex problems in constantly changing conditions. However, many circumstances make the real implementation of effective scenarios generated by simulation software tools difficult. One of them are rigid working schedules that complicate flexible human resources planning in accordance with optimal production and logistics plans. This article aims to examine the role of the digital factory twin in advanced human resources planning. Using the case study method, a solution for better coordination of internal logistics processes and utilization of logistics staff based on discrete-event simulation is presented. Several scenarios were tested and results showed the inevitability of using flexible working schedules for maximum utilization of logistics staff. The purpose of this study is not only to show one special case of one company, but to emphasize the potential of these software tools to achieve long-term synergies in coordinating logistics, production and human resources management activities. As a result of this study, an extended physical-digitalphysical loop model is presented. This extension consists in adding the second loop including communication with HR portal.

Full textAbstract:
Stakeholder engagement is increasingly recognized as a critical factor in advancing sustainability practices within circular economy models. As the traditional linear economy shifts towards circular principles emphasizing resource efficiency, waste reduction, and lifecycle management the involvement of diverse stakeholders becomes pivotal in achieving these sustainability goals. This paper explores the integral role of stakeholder engagement in driving effective circular economy practices and highlights key strategies and outcomes associated with successful stakeholder involvement. Circular economy models aim to create closed-loop systems where resource use is optimized, products are designed for longevity and recyclability, and waste is minimized. Stakeholders, including internal actors (employees, management) and external entities (suppliers, customers, regulators), each play unique roles in supporting these objectives. Effective stakeholder engagement facilitates the alignment of diverse interests and fosters collaboration necessary for implementing circular practices. By actively involving stakeholders, organizations can leverage their insights, address their concerns, and build consensus around sustainability goals. Strategies for effective stakeholder engagement include transparent communication, collaborative partnerships, and incentive structures. Transparent communication ensures that stakeholders are well-informed about sustainability initiatives and their potential impacts. Collaborative partnerships, both within and outside the organization, enable the pooling of resources, knowledge, and expertise, enhancing the effectiveness of circular economy practices. Incentive structures, designed to align stakeholder interests with sustainability goals, can motivate stakeholders to contribute actively and support circular initiatives. Case studies reveal the positive impact of stakeholder engagement on circular economy outcomes. For instance, organizations that have successfully engaged stakeholders often report improved resource efficiency, increased innovation in sustainable product design, and enhanced waste management practices. Conversely, challenges such as misalignment of interests, communication barriers, and resistance to change can hinder effective engagement. Addressing these challenges through tailored strategies and continuous feedback mechanisms is crucial for sustaining stakeholder involvement and achieving circular economy objectives. The future of stakeholder engagement in circular economy models will likely be shaped by emerging trends and evolving regulatory landscapes. Innovations in engagement practices and policies will further enhance the effectiveness of circular economy initiatives. Organizations are encouraged to adopt best practices for stakeholder engagement, continuously evaluate its impact, and adapt strategies to meet changing expectations and challenges. Stakeholder engagement is a key driver of sustainability within circular economy models. By fostering transparent communication, collaboration, and alignment of interests, organizations can effectively implement circular practices and achieve significant sustainability outcomes. The evolving landscape of stakeholder engagement promises further advancements in circular economy practices and underscores the importance of active and inclusive stakeholder involvement in driving sustainability.

Full textAbstract:
The servitisation of the built environment, through the implementation of product–service systems, is considered a promising business strategy to achieve a circular economy transition. This servitisation faces a number of practical challenges, among them the technological readiness and effective integration and application of existing and emerging products, manufacturing processes, and digital monitoring and management tools. The research builds on targeted literature review, and on a research-through-design approach based on full-scale pilot projects developed in an ongoing feedback loop between researchers, planners, and industry partners representing both the demand and supply sides of the façade industry in the Netherlands. The paper analyses the technical implementation challenges currently preventing the façade industry from adopting performance-based contracts. It then proposes the roles that existing and emerging digital design and engineering technologies, manufacturing processes, and asset management systems can play in the development, implementation, and fulfilment of such contracts. The paper proposes a multi-stakeholder, systemic model for the development and application of façade technologies capable of overcoming many of the technical implementation barriers to the delivery of performance-based contracts for integrated facades. From this it concludes that an effective development of building technologies should strategically align with the solving of economic and contractual challenges such as circularity-readiness, profitability, risk distribution, legal demarcation, performance monitoring, and residual value stewardship. The resulting framework provides a strategic and conceptual basis for the development of circularity-enabling façade technologies, accounting for the diverse and sometimes conflicting interests of the multitude of stakeholders involved throughout a project’s lifecycle. The framework aims to support planners, manufacturers, and builders accelerate the circular deep energy renovation of the built environment while also exploring new business opportunities.

Full textAbstract:
The article aims to reveal the transition and evolvement of the Project management in its variety and benefits that brings for the business organization. There will be reviewed three main concepts for Project management: Lean, Agile and DevOps. Lean concept concentrates its efforts to deliver more value with less waste by reducing everything that does not add value. In other words: Doing more with less. An organization that applying Lean Methodology is aiming to provide perfect value to customers following perfect process of creating value with zero waste. There are key principles which guide the actions for applying Lean techniques. In order to do this the experts have to perform Lean thinking. In other hand the main philosophy in Agile approach is striving for the same costs and at the same time but improving work so that the customers remain satisfied. There have been various frameworks like Scrum and Kanban which offers different tools to manage projects and refer to Agile Project Management. It encourages adaptive planning, evolutionary development, early delivery, and continual improvement. Agile approach leads to rapid and flexible response to changes. This method is highly used and beneficiary in complex projects where the situations are constantly changing. Lean and Agile approaches have many things in common. Both of them are seeking to add value and prefer working in small badges to avoid large mistakes. Different approaches effect in different way for different organizations. In an effort to avoid some disadvantages there is some companies that moved towards DevOps. DevOps Approach also is a method in strong connection with Lean and Agile methods by steer them to operations work. While Agile Project Management focuses its efforts to Development (Dev), there is still a loop which needs to be covered – Operation function (Ops). Participating of the development and operations experts together in the entire product or service lifecycle is the main concept of the DevOps. The soft skills of the people that are expected to adopt and move by the principles of any philosophy have an important role. The way they think and execute their responsibilities are as important as the principles itself. The tools are useless if the people are not willing and don’t know how to use them. Every one of those philosophies strives to answer challenges of the business environment and rapidly changing customer`s needs with different tools. The collaboration between them and the transition from one to another shaped Smart concept for Project Management which puts in front quality, customer feedback and continuous delivery and deployment.

With awareness of environmental protection strengthens and constraints of regulations and laws to environmental protection increasing, more and more enterprises focus on the closed-loop supply chain management. Considering difference between new product and remanufactured product, this paper constructs closed-loop supply chain system with manufacturers recycling used products directly from the consumers based on game theory. The optimal pricing decisions and the optimal profit of centralized and decentralized closed-loop supply chain are obtained. It is found that the efficiency of decentralized closed-loop supply chain decreases by 25%. At last, the coordination mechanism is designed to solve the profit conflict in the decentralized closed-loop supply chain by the two-part tariff contract.

Full textAbstract:
In order to cope with the issue of depletion of natural resources, expectations for economical designs of the closed-loop supply chains of products that include remanufacturing in their lifecycle have recently significantly grown. However, since disassembly of a product to remanufacture it is costly due to high labor costs, the lifecycle option of remanufacturing an end of life product by disassembly and reassembly needs to be established environmentally as well as economically. In this study, we propose a remanufacturing option selection method that takes recovery rates and profits into account. First, a bill of materials of a product is prepared to create data for remanufacturing. Next, its remanufacturing option selection is formulated by using the 0-1 integer programming. Lastly, the proposed remanufacturing option selection method is verified by analyzing the sensitivities of the recovery rates and selling prices of the remanufactured products using the ϵ constraint method. The proposed method that takes remanufacturing into account has demonstrated a generating larger profits than a conventional method maintaining high recovery rates at the same levels in a case study.

Full textAbstract:
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 different stages in the supply chain, as well boost smart remanufacturing techniques. This review examines how strategies like design for remanufacturing (DfRem), remaining useful life (RUL), product service system (PSS), closed-loop supply chain (CLSC), smart remanufacturing, EoL product collection and reverse logistics (RL) can enhance remanufacturing. We should bear in mind that not all products can be remanufactured, so other options are also considered. This review mainly focuses on products that can be remanufactured. For this review, we used 181 research papers from three databases; Science Direct, Web of Science and Scopus.

Introduction. New cyclical business models can develop at all stages of the product lifecycle. Digitalization can lead to breakthrough innovations, new business models and new ways of cooperation and, thus, accelerate the economic transition to more resource-saving and closed production systems. Goal. The study of the features of digitalization as a driving force of business models of the closed-cycle economy. Materials and methods. There is little empirical research on the stimulating role of digitalization in a closed-loop economy. To eliminate this gap, the article explores the role of digitalization in simplifying cyclical business models based on an empirical analysis of a data set of 599 Russian manufacturing firms and 296 industrial service providers. Results and discussion. While relatively few Russian firms rely on new business models to implement their resource efficiency strategy, we believe that this share is higher for companies with a strong focus on digital technologies in the manufacturing sector. This suggests that digitalization can indeed become the driving force behind the introduction of cyclical business models. Conclusion. The integration of cyclicity into business models is a key lever for the transition to a closed-loop economy. Despite the fact that it is widely recognized that digitalization causes disruptions in a wide range of areas, there is not enough literature linking this concept with the closed-loop economy and confidence-building measures as a means of contributing to disruptions in the closed-loop operation. This article examines this gap by conceptualizing cyclical disruption, which can become a key factor in accelerating the transition to a closed-loop economy. There is a wide range of DTS that can contribute to the breach of mutual responsibility and innovative ways of doing circular business discussed in this article.

Full textAbstract:
This research focuses on the relation between time variation and the behaviors of a closed-loop supply chain with stochastic product returns. In recent years, activities that reduce environmental impact, such as recycling and reusing materials, have been increasing. Designing a closed-loop supply chain for recycling or reuse operations will support social responsibility and competitive advantage. However, in order to establish supply chains for sustainability, it is necessary to consider not only environmental benefits but also economic efficiency. Moreover, both the quantity of demand and returns are indefinite in an actual closed-loop supply chain. In this study, we assume that the arrival interval of return inward follows a logarithmic normal distribution. Further, we design basic models with a manufacturing and remanufacturing process to understand the behavior of a closed-loop supply chain with stochastic product returns in a finite horizon and investigate the influence of different choices in management on the cost and environmental factors.

Abstract—As electric vehicles (EVs) gain momentum as a solution to reduce greenhouse gas emissions and fossil fuel dependence, their supply chains become increasingly complex, particularly for lithium-ion batteries (LIBs), which are crucial for EV performance, safety, and longevity. This paper reviews existing literature on several key aspects of the EV supply chain, focusing on thermal management systems (TMS), lifecycle environmental assessments, closed- loop supply chains (CLSCs), and the impacts of global disruptions like the COVID-19 pandemic. Research by Murugan et al. (2022) underscores the importance of improving TMS for LIBs, noting that experimental validation remains sparse despite advances in numerical modeling. In addition, Rüdisüli et al. (2022) highlight the environmental benefits and limitations of different mobility technologies, emphasizing the need for advancements in seasonal energy storage systems. Gu et al. (2018) discuss the challenges of establishing profitable CLSCs for EV batteries, where reuse improves sustainability, but recycling faces economic hurdles. Finally, the analysis of Wen et al. (2021) on the COVID-19 pandemic’s impact shows significant disruptions to the Chinese EV market and raises concerns about the global EV supply chain’s resilience. This review identifies gaps in the literature, such as the need for real-world validation of models, exploration of alternative battery chemistries, and improved supply chain governance, all of which are essential for advancing the EV industry toward sustainability. Keywords—Electric Vehicles, Supply Chain Management, Lithium-ion Batteries, Thermal Management Systems, Closed-Loop Supply Chains, Sustainability, Greenhouse Gas Emissions, Lifecycle Assessment, Resource Dependencies, Circular Economy.

This study develops a circular supply chain management model. The review shows how CSCM promotes green supply chain management and sustainability by extending its sustainable dimension beyond the original producer. Closed-loop and open-loop supply chains are CSCM components. Using contingency theory and transaction cost theory, the CSCM model proposes that product circularity in closed-loop and open-loop supply chains affects a company's circular economy performance. This model explains CSCM's popularity in current literature, which supports the circular economy. Keywords: Circular, Closed-loop, Open-loop, Sustainability, Supply Chain eISSN: 2398-4287© 2022..

Full textAbstract:
In the closed-loop supply chain system of component remanufacturing, new parts suppliers are likely to be affected by certain factors that lead to sudden increases in supply prices, and this sudden increase in new parts prices may trigger the chain collapse of the closed-loop supply chain system and impact the stability of the closed-loop supply chain. Therefore, this paper combines closed-loop supply chain theory, evolutionary game theory, and system dynamics theory, which are internalized to construct a complex system model. Furthermore, the impact of different price increases of new parts on the stability of the closed-loop supply chain is analyzed through scenario simulation. The results show that a 25% increase in the price of new parts will delay the time for remanufacturers and retailers to reach a stable state of product flow, reduce the profitability of remanufacturers and retailers, and inhibit the willingness of remanufacturers to carry out high-green production in the early stage. A 50% increase in the price of new parts can break the closed-loop supply chain from the remanufacturer, severely undermining the stability of the closed-loop supply. According to the simulation results, this paper presents a timely government dynamic reward and punishment optimization scheme for remanufacturers to improve the tolerance level of the closed-loop supply chain for the price increase of new parts and to provide a reference for enhancing the stability of the closed-loop supply chain and optimizing the government supervision strategy.

The remanufacturing warranty strategy has become an effective mechanism for reducing consumer risk and stimulating market demand in closed-loop supply chain management. Based on the characteristics of consumers’ behavior of purchase decisions, this paper studies the warranty decision model of remanufacturing closed-loop supply chain under the Stackelberg game model. The present study discussed and compared the decision variables, including remanufacturing product pricing, extended warranty service pricing, warranty period and supply chain system profit. The research shows that consumers’ decision-making significantly affirms the dual marginalization effect of the supply chain system while significantly affecting the supply chain warranty decision; the improved revenue sharing contract and the two charge contracts respectively coordinates the manufacturer-led and retail-oriented closed-loop supply chain system, which effectively implements the Pareto improvement of the closed-loop supply chain system with warranty services. In the present study, the model is verified and analyzed by numerical simulation.

Full textAbstract:
In this paper, we aim to explore the operational performance of a green closed-loop supply chain under random events. A green closed-loop supply chain model based on generalized stochastic Petri nets (GSPN) is built using the Petri nets theory. According to the isomorphic relationship between GSPN and continuous-time Markov chains, the relevant Markov model is converted from GSPN, and the steady-state probability of the model is then calculated. Finally, the model is analyzed from the aspects of time performance and operation efficiency of each link. Compared to previous studies, this paper finds that: when the whole green closed-loop supply chain system reaches a dynamic equilibrium state, the product has a steady-state probability at all stages, and thus the overall operational performance of the system can be obtained; compared with the recycling of waste products, the green product takes a longer time in the production and distribution stages; since marketing, packaging processing, market feedback, and market demand formulation account for a high level of utilization throughout the life cycle of green products, decision makers need to focus on the supervision and management of these links. Managers of green closed-loop supply chain systems need to adjust their decision-making strategies in a timely manner according to the performance level of the system in the steady state to realize the efficient operation of the system. This paper not only provides theoretical support for the improvement of the operational efficiency of green closed-loop supply chain system, but also provides new ideas for the research of green closed-loop supply chain operation mode.
