Tidskriftsartikel (refereegranskat)abstract
- Traceability has emerged as a prime requirement for a multi-tier and multi-site production. It enables visibility and caters to the consumer requirements of transparency and quality assurance. Textile and clothing industry is one such example that requires traceability implementation to address prevailing problems of information asymmetry and low visibility. Customers find it difficult to access product data that can facilitate ethical buying practices or assure product authenticity. Besides, it is challenging for stakeholders to share crucial information in an insecure environment with risk of data manipulations and fear of losing information advantage. In this context, this study investigates and proposes a blockchain-based traceability framework for traceability in multi-tier textile and clothing supply chain. It conceptualizes the interaction of supply chain partners, and related network architecture at the organizational level and smart contract and transaction validation rules at the operational level. To illustrate the application of the proposed framework, the study presents an example of organic cotton supply chain using blockchain with customized smart contract and transaction rules. It finally demonstrates the applicability of the developed blockchain by testing it under two parameters. The proposed system can build a technology-based trust among the supply chain partners, where the distributed ledger can be used to store and authenticate supply chain transactions. Further, the blockchain-based traceability system would provide a unique opportunity, flexibility, and authority to all partners to trace-back their supply network and create transparent and sustainable supply chain.

Konferensbidrag (refereegranskat)abstract
- Supply chain traceability has emerged as a prime requirement for multi-tier supply chains. It not only enables the supply chain visibility but also caters to the consumer requirements related to transparency, quality assurance, and production tracking. Nonwoven supply chain is one such example that particularly requires traceability implementation due to prevailing problems related to information asymmetry and complex supply chain networks. Conversely, it is challenging for supply chain partners to share all the competitive information in the unsecure environment. In this context, in line with Industry 4.0, this study investigates blockchain technology, which uses a shared and secured data infrastructure to keep track of information about assets and requires no central authority to function. It further proposes a blockchain-based traceability framework that explains supply chain partner interaction and network architecture at organizational level and smart contract and transaction validation rules at the operational level. In order to illustrate the application of the framework, the study presents an example of a nonwoven supply chain to track the nonwoven manufacturing and distribution processes. The proposed system can build a technology-based trust among the supply chain actors, where the distributed ledger would be used to store and authenticate of supply chain transactions.

Ingår i: Textiles and Clothing Sustainability. - : Springer Science and Business Media LLC. - 2197-9936. ; 3:5
-
Tidskriftsartikel (refereegranskat)abstract
- Sustainability is a widely recognized concern and priority for healthy growth of the society and for preservation of the planet. Concerning this, textile sector has seen an unprecedented demand for sustainable products from the consumers, responding to which organizations have undertaken different initiatives. One of the major concerns in the textile sector is its complex supply chain networks and the involvement of numerous actors dealing with diverse raw materials and operations. The effective implementation of sustainability at the industrial scale would require the participation of all supply chain actors, along with an efficient traceability system to monitor and analyze different sustainability aspects. Furthermore, traceability is an integral part of the recycling process which contributes towards the sustainability. Therefore, the present article focuses on the contribution of traceable information towards attaining the sustainability in the textile sector. The three pillars of sustainability, namely, ecological, societal, and economic, are discussed for their relation and dependency on the traceability followed by an overview of the challenges in successful implementation of the traceability system, which is anticipated to shape the future research questions.

Tidskriftsartikel (refereegranskat)abstract
- Textile and clothing industry is one of the oldest manufacturing industries and is a major contributor in the economic growth of developing countries. However, from past few decades, it has been criticised for its opaque, unsecured and untraceable nature of supply chain. Addressing these challenges, the paper proposes a system approach to introduce an item-centric secured traceability concept to monitor and control manufacturing processes and supply chain activities. In order to implement such secured traceability system, the paper describes the process for manufacturing, encoding and validating an innovative two-factor secured tag based on particle randomness that is printed on the surface of textile. Being micro-sized, the particles are easy to read and validate with pattern recognition. Further, as achieved through an uncontrolled manufacturing process, the randomness is unclonable to produce counterfeit tags. Furthermore, a sequence of experimental analyses has been conducted using various simulated scenarios to verify its applicability. A secured tag can be a low-cost and durable substitute for detachable, unsecured identifiers commercially available in the market.

Blockchain-Based Secured Collaborative Model for Supply Chain Resource Sharing and Visibility
- 2020
-
Ingår i: IFIP Advances in Information and Communication Technology. - Cham : Springer. ; , s. 259-266
-
Konferensbidrag (refereegranskat)abstract
- Globalization, escalating competition, and demand for sustainable practices have required supply chain and production managers to consider various capabilities and value creation strategies for the customers. Rapid technological advancement in the current production environment calls for integrative and collaborative efforts for effective resource utilization and better visibility to gain competitive advantages. However, privacy risks and trust have always been a significant barrier for organizations’ efforts towards supply chain integration. Supply chain stakeholders fear these collaborate practices might weaken their bargaining power, accelerate risk of data manipulation and result in loss of information advantages. Addressing these issues, the study proposes a Blockchain-based collaborative model for production visibility and resource sharing. It demonstrates the framework for stakeholders’ interaction over a central procurement system backed with blockchain technology. The study further lays down the notion of production capacity backed smart contract rules. These smart contracts will run on the proposed blockchain network to reduce the possibilities of fraudulent transactions and capacity overbooking- leading to illegitimate subcontracting. The overall network will stimulate visibility and develop a technology-based trust among partners which ensuring sustainability by effective utilization of resources.

Contribution to development of a secured traceability system for textile and clothing supply chain
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Secured traceability implies not only the ability to identify, capture, and share required information on product transformation throughout the supply chain (SC), but also the ability to ensure the security of the traceability data. Due to information asymmetry and lack of transparency, textile and clothing (T&C) industries often face challenges in implementing and maintaining sufficient traceability. The SC actors find it difficult to identify and track the suppliers and sub-suppliers involved. Additionally, the opaque and largely untraceable structure of the SC has enabled the easy intrusion of counterfeits. Hence, a secured traceability system is imperative to ensure that the required traceability data are captured and shared among SC actors, thereby allowing the tracking and tracing of the products in the SC. Further, a secured traceability system helps organizations in various decision-making processes and protects customers from counterfeits. This thesis contributes to the development of a secured traceability system for the T&C sector. It examines traceability at product and information levels, based on the system-of systems approach. At the product level, the thesis introduces a secured traceability tag that can be printed on the textile surface. The secured tag is hard to copy and is durable enough to withstand normal textile use, thus providing sufficient security besides product tagging for traceability implementation. At the information level, the thesis explores and classifies traceability data that can be shared at business-to-business and business-to customer levels for the implementation of secured traceability. Subsequently, a block chain-based traceability framework is proposed for the T&C supply chain to systematically capture and share data in the supply chain network. The proposed framework demonstrates the applicability of shared data infrastructure to traceability without a central authority and develops technology-based trust among the supply chain actors. It relies on no central authority, and has customized data privacy and accessibility rules, thus providing a unique opportunity, flexibility, and authority to all supply chain actors to trace their supply chains and create transparent and sustainable supply chain networks.

Tidskriftsartikel (refereegranskat)abstract
- Blockchain technologies can support traceability, transparency and trust among participants. This has primarily been explored in established supply chains and not in the growing use of business networks or ecosystems, which is a notable limitation since supply chains typically are organised with a dominant actor that ensures common information systems and standards that negate blockchain benefits. Hence, this study explores the design of a blockchain-based collaborative framework for resource sharing using smart contracts. These are particularly well-suited for supporting operations in broader networks or ecosystems beyond supply chains with established collaborations and hierarchies. Based on a systematic literature review, a demonstrator framework was developed for stakeholder interactions through a procurement and distribution unit backed with blockchain technology. The framework consists of (a) network architecture to demonstrate partner interactions; (b) rules for network working principles based on supply collaboration requirements; (c) UML diagram to define smart contract interaction sequence; and (d) algorithm for smart contract network verification and validation. Applicability of these smart contracts was verified by deployment on an Ethereum blockchain. The demonstrator framework ensures quality and data authenticity in supply networks, so it is useful for effective resource utilisation in networks where outsourcing and production surpluses are major issues.

- 2018
-
Ingår i: The International Journal of Advanced Manufacturing Technology. - London : Springer London. - 0268-3768 .- 1433-3015.
-
Tidskriftsartikel (refereegranskat)abstract
- Product security is one of the major concerns in the textile industry. Every year, fashion brands suffer significant loss due to counterfeit products. Addressing this, the paper introduces a secured tag for traceability and security of textile products. The proposed tag is unclonable, which can be manufactured using conventional screen-printing process. Further, it can be read using a smartphone camera to authenticate the product and trace its history. Consequently, imparting additional functionality to the textile through surface modification. To validate its applicability, the study experimentally investigates the durability and readability of the developed secured tag using three different binders on polyester and cotton textiles substrates. A comparison is presented with an in-depth analysis of surfaces and binders interaction at different stages of the secured tag lifecycle, i.e. before print, after print, after wash and after abrasion cycles. The methodology and findings of the study can also be useful for other manufacturing domains dealing with the printing process.

Konferensbidrag (refereegranskat)abstract
- With the increased electrification of transportation, there is a growth in the number of electric vehicles (EV) in use, and hence also discarded EV batteries. It is critical to trace the batteries so that the policy of electrification does not lead to a negative impact on sustainability. To achieve the goals of circular economy, it is necessary to consider the sustainable extended life cycle strategies of reduce, reuse and recycle. Information gathering and sharing through the supply chain is the key driver for enabling the tracking and tracing of materials and services needed. Traceability indicators across the value chain may enable the creation of a comprehensive database that aids the circular economy goals. In this study, we discuss three different circular economy business models and identify the key traceability indicators for enabling circularity in the lithium-ion battery application in the automotive sector. Insights are used to develop a framework for viable EV battery circularity, capturing three key circular economy elements and four traceability characteristics for different circularity types.

Exploring secured traceability systems for implementation in textile and clothing supply chain
- 2018
-
Ingår i: Proceeding TIWC conference 2018.
-
Konferensbidrag (refereegranskat)abstract
- Information asymmetry and security are major challenges in multi-tier supply chains. Textile and clothing (T&C) supply chain is one such example significantly affected by these problems. Due to its complex and diverse nature, involved actors find it difficult to connect and secure each supply chain links. Exploiting this situation, a parallel counterfeit market is flourishing and gaining serious momentum. Due to this, T&C industries are suffering huge economic losses and job cuts. Additionally, owing to its opaque and untraceable supply chain, T&C industries have become a world of unethical practices. Secured traceability is an effective tool that has potentials to address these issues and make the T&C supply chain transparent and secured. It is a useful mechanism to track and trace products’ history, know about the manufacturing conditions and at the same time secure it from counterfeits and attacks targeting intellectual properties. In this context, the study conduct survey of supply chain experts to explore and rank the key technological requirements (based on the specific nature of the textile product) and traceability information that can be recorded and secured by a secured traceability system. Further, based on the findings of the survey a review of the literature was conducted to explore state of the art technologies to propose a primary secured traceability structure for the T&C supply chain.

Implementing traceability using particle randomness-based textile printed tags
- 2017
-
Konferensbidrag (refereegranskat)abstract
- This article introduces a random particle-based traceability tag for textiles. The proposed tag not only act as a unique signature for the corresponding textile product but also possess the features such as easy to manufacture and hard to copy. It seeks applications in brand authentication and traceability in textile and clothing (T&C) supply chain. A prototype has been developed by screen printing process, in which micron-scale particles were mixed with the printing paste and printed on cotton fabrics to attain required randomness. To encode the randomness, the image of the developed tag was taken and analyzed using image processing. The randomness of the particles acts as a product key or unique signature which is required to decode the tag. Finally, washing and abrasion resistance tests were conducted to check the durability of the printed tag.

Konferensbidrag (refereegranskat)abstract
- Textile and clothing (T&C) industry is characterised by complex and extensive supply chain involving various stakeholders dealing with diverse raw materials. Owing to these complexities, the textile supply chain is facing numerous challenges like, counterfeit products, limited information sharing, ineffective recycling/reuse of textile products, unethical practices and interrupted information flow. As a result, a secured traceability system that can integrate the whole value chain, record, store, and track / trace all supply chain activities, make it more transparent and at the same time safeguard it from unauthorized access, has become a prime requirement for the T&C industry. In this context, the current study conducts a literature review to identify the generic requirements of traceability and in context of T&C closed-loop supply chain (CLSC). It further evaluates the role and key requisites of a cryptographic tag for textiles product, as an additional measures/parameter to secure the traceability system and prevent unauthorised access. Finally, the paper draws on key characteristics of such cryptographic tag for textile CLSC and lay down the tentative methodology that would be followed in the future research for development of a complete secure traceability system. It is anticipated that such secured traceability system can prevent counterfeits, data leakage, bring transparency and automate the reverse logistic process.

- 2019
-
Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 11:06
-
Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study is twofold. First, to explore and classify factors influencing traceability implementation, and second, to cluster essential traceability-related information that demands recording and sharing with businesses and customers, in the context of the textile and clothing supply chain. A Delphi study is conducted with 23 experts (including research practitioners and industry experts) to explore, validate, and classify traceability factors and related information using distribution analyses and hierarchal clustering. As a result, 14 factors and 19 information sets are identified and classified with a moderately high agreement among the experts. Among these, risk management, product authentication, and visibility are the highest ranked and the most important factors influencing traceability implementation in the textile and clothing supply chain. While origin, composition, and sustainability-related information are crucial for sharing with customers, the information vital to businesses includes manufacturer/supplier details, product specifications, and composition. It is noteworthy that this research is among the few that classifies traceability factors and information through expert perspectives, and it creates decisive knowledge of traceability for the textile and clothing supply chain. It further provides insights on the extent to which this information can be shared among supply chain actors. Outcomes of this study can be helpful for the development of an information traceability framework. Policymakers can use the results to draft traceability guidelines/regulations, whilst top management can develop traceability-related strategies.

Konferensbidrag (refereegranskat)abstract
- Visibility in production logistics and across the supply chain has become a key concern for organizations. Its need has been further emphasized due to the current COVID 19 crisis. Organizations find it challenging to prepare the internal logistics and supply chain, and quickly respond to such unexpected events, due to low visibility. Against this backdrop, the paper, which is a work-in-progress, systematically documents different factors influencing supply chain visibility and crucial information that should be collected and shared among supply chain partners for better visibility. A Delphi analysis is being conducted with twenty-six supply chain experts from various globally recognized enterprises with manufacturing units located worldwide. The study starts with a short open-ended questioner to collect a comprehensive list of antecedents, drivers, barriers, effects, and visibility information based on the qualitative response from the experts. The preliminary results from the first round of the Delphi analysis indicate that risk management, environmental sustainability, and supply chain control are some of the key drivers. Lack of IT infrastructure and maturity are some of the barriers, integrated systems, and technology maturity are among the key antecedents and gaining planning capability and better customer service are some of the positive effects of supply chain visibility as per the experts’ opinion. In addition, information related to planning, supplier location, and deviation are among the crucial ones that require the collection and sharing for better supply chain visibility. This research study is among the few that empirically explores factors influencing supply chain visibility and generates new insights as to why the barriers can be difficult to overcome in complex supply chain settings.

An Optimization Model with Stochastic Variables for Flexible Production Logistics Planning
- 2022
-
Ingår i: Advances in Transdisciplinary Engineering. - : IOS Press. ; , s. 435-446
-
Konferensbidrag (refereegranskat)abstract
- Production logistics has an important role as a chain that connects the components of the production system. The most important goal of production logistics plans is to keep the flow of the production system well. However, compared to the production system, the level of planning, management, and digitalization of the production logistics system is not high enough, so it is difficult to respond flexibly when unexpected situations occur in the production logistics system. Optimization and heuristic algorithms have been proposed to solve this problem, but due to their inflexible nature, they can only achieve the desired solution in a limited environment. In this paper, the relationship between the production and production logistics system is analyzed and stochastic variables are introduced by modifying the pickup and delivery problem with time windows (PDPTW) optimization model to establish a flexible production logistics plan. This model, taking into account stochastic variables, gives the scheduler a new perspective, allowing them to have new insights based on the mathematical model. However, since the optimization model is still insufficient to respond to the dynamic environment, future research will cover how to derive meaningful results even in a dynamic environment such as a machine learning model.

- Events such as Covid-19 have revealed the vulnerabilities that companies face due to low visibility. Consequently, companies experience impact on their supply chains in terms of disruptions of material supply, deliveries, productivity and revenue. Thus, the importance of Supply Chain Visibility (SCV) in global and competitive markets with increasing sustainability demands has received widespread recognition. Yet, the literature provides limited understanding of requirements to consider when developing a SCV system. Addressing the gap, this study presents the findings from a case study during the first months of 2021 at a global manufacturing company developing a SCV system to improve their inbound flow. Using a system engineering perspective, this study presents requirements highlighted during early stage for a SCV system. The results indicate the importance of ensuring SCV system requirements to enable data collection, handling and usage for decision making leading to both supply chain sustainability and resilience. This study contributes to the understanding of SCV by presenting and categorizing requirements considered for real-time case at a manufacturing company when developing a SCV system.

Supply chain visibility for improving inbound logistics : a design science approach
- 2023
-
Ingår i: International Journal of Production Research. - : Taylor & Francis. - 0020-7543 .- 1366-588X. ; 61:15, s. 5228-5243

Tidskriftsartikel (refereegranskat)abstract
- Supply chain visibility (SCV) has been gaining recognition in recent years as a key factor for achieving analytical capabilities and improving supply chain performance. However, levels of SCV implementation lag behind current technological advances. This research was motivated by the lack of visibility in inbound logistics, which limits the possibility of managing deviation, in particular concerning changes in arrival time of incoming goods, in large industrial firms. We addressed this problem by adopting a design science approach. In particular, we followed context–intervention–mechanism–outcome (CIMO) logic to map and analyse material and information flows. The problems areas were successively translated via business and functional requirements into technological solutions. We evaluated alternative technologies using controlled experiments that mimicked real-life situations. This study provides guidance for manufacturing companies aiming to enhance deviation management and predictive capabilities by improving visibility in their inbound logistics and potentially extending visibility to other areas, such as internal and outbound flows.

Forskningsöversikt (refereegranskat)abstract
- Supply chain visibility is a concept that is gaining increasing attention. Increasing levels of visibility in the supply chain is considered beneficial in many respects. A systematic literature review identified 47 empirical research papers from international scientific journals. Two main findings emerged from the content analysis. First, the perspectives provided in the extant literature can be grouped into four categories: antecedents, barriers and challenges, drivers, and effects. The effects include both capabilities and operational performance. Second, the few models on supply chain visibility include only antecedents and effects, and do not capture the perspectives of barriers, challenges, or drivers. We present a framework for supply chain visibility driven by insights from the content analysis. The ABCDE framework includes antecedents (A), barriers and challenges (BC), drivers (D), and effects (E), and provides a holistic view of supply chain visibility. The framework can aid managers with per-spectives and factors to consider when discussing, implementing, and improving supply chain visibility and provides researchers with a state-of-the-art review of supply chain visibility. We also propose an agenda for further research.

Tidskriftsartikel (refereegranskat)abstract
- The rapid uptake of electric vehicles (EVs) will be vital to decarbonise the transport sector and achieve climate change targets. However, this transition is leading to an increased demand for key battery materials and associated resource challenges and supply-chain risks. On the other hand, discarded EV batteries create business opportunities for second life and recycling. This study presents scenario-driven material flow analysis (MFA) to estimate the future volume of EV battery wastes to be potentially generated in Sweden and future demand for key battery materials, considering potential EV fleet, battery chemistry developments, and end-of-life strategies of EV batteries. Further, we combine MFA with a socio-technical approach to explore how different socio-technical developments will affect both EV battery flows and the underlying systems in the future. Recycling has the potential to reduce primary demand by 25–64% during 2040–2050 based on projected demand, meaning that waste streams could cover a considerable part of the future raw material demands. Second-use of EV batteries can promote circularity yet postpones recycling potentials. From a transition perspective, promoting recycling, second-life use of EV batteries and advanced battery technologies entail system disruption and transformational changes in technology, markets, business models, policy, and infrastructure and user practices. Demand for high-capacity batteries for grid decarbonisation and aviation applications may contribute to the emergence of niche battery technologies. Each scenario highlights the need for effective policy frameworks to foster a circular EV battery value chain.
