The flattening of sales channels makes it easy for an upstream core parts supplier in an assembly supply chain to invade the downstream market. This also introduces several challenges for the efficient performance and management of the supply chain system. Whereas restrictive factors such as supplier confidentiality agreements have limited the product encroachment by the suppliers, the adoption of blockchain technology for improving information diaphaneity and efficiency of the supply chain can potentially encourage market intrusion by the suppliers. Therefore, whether blockchain technology can be successfully accepted and implemented by both the suppliers and incumbent manufacturers, and how this can be achieved, are issues that need urgent attention in the case of supply chain systems. In this paper, we establish a two-stage assembly supply chain consisting of an incumbent manufacturer and a core component supplier that invades the downstream market with imitation products, in order to analyze the impact of supplier encroachment and the application of blockchain technology on the assembly system. The results show that it is more beneficial to play the dual role of core supplier and product manufacturer than to only be a core supplier. Similarly, when the cost of implementing blockchain technology is lower than a specific threshold, the implementation of blockchain is always beneficial for the encroaching supplier, whereas the manufacturer does not always benefit. The blockchain not only improves the selling price of the core component produced by the supplier, but also improves the quality of the core component and increases the total market demand. Finally, in view of the potential benefits and conflicts that may arise from the implementation of the blockchain, we design corresponding ex-ante, ex-post and hybrid coordination mechanisms to achieve a win-win situation in this competitive system. Our modeling work and results provide useful managerial insights regarding the encroachment by core component suppliers and the implementation of blockchain technology in assembly supply chains.

Balancing efficiency and resilience in any supply chain commences from its ability to secure supplier networks. Blockchain technology applications in procurement can work as a major enabler in this process. Despite the unquestionable relevance of Blockchain Technology (BCT)-integrated Procurement, no comprehensive review exists. Considering this significant research gap, the present study aims to provide a comprehensive literature review by deeply examining 95 highly relevant papers published from January 2012 to Sep 2023. Existing literature studies suggest BCT as the imitable enabler of the Procurement 4.0 era, yet the topic has not been fully explored and researched. This study identifies noteworthy deficits in theoretical underpinnings, technological contributions in generating new revenue models, radical impacts anticipated on the procurement organization restructuring, and so forth. The research is timely and importantly advantageous because it offers a holistic view of relevant literature-driven evidence about a range of existing dimensions on the subject. More specifically, this study provides exhaustive key recommendations for future research on BCT applications in procurement utilizing the Theory, Context, and Methodology (TCM) framework.

Abstract The emergence and subsequent popularization of lean manufacturing have become one of the most significant for improving the efficiency and productivity of operations. The use of lean manufacturing tools and methods leads to the elimination of waste in the organization. Traditional information systems that allow organizations to share information about resources while managing process performance and traceability have a number of disadvantages such as security, interoperability, and transparency. Currently, distributed ledger technology (block-chain) is widely used for this purpose. This article presents a study of decentralized management of the implementation of a distributed ledger infrastructure, which is selected based on the characteristics of the production system. This study proposes a framework that analyzes lean production methods using simulation and data envelopment analysis (DEA) to accommodate the underlying multi-objective decision-making problem. The current study examines the impact of the simultaneous application of RCA technology, lean manufacturing methods, and distributed ledger technology on the total time, costs, and time of production processes.

Abstract Companies and industries face various challenges when it comes to embracing the circular economy (CE). These challenges not only deter companies from adopting effective strategies that promote it but also hinder industries from effectively establishing a circular system that ensures the addition of economic value to the supply chain. To address these challenges, blockchain technology has emerged as a new and revolutionary protocol for sharing and updating information. It does so by linking databases within a decentralized, peer‐to‐peer, open‐access network, guaranteeing secure, immutable, and irreversible operations. Within this context, the primary objective of this article is to investigate how blockchain technology supports the transition to the CE. Additionally, the paper aims to identify the barriers that hinder the process of transitioning to the CE. To achieve this, a systematic literature review (SLR) was conducted, considering 22 articles published in recent years across Scopus, Web of Science, and Science Direct databases. The results of this review underscore the considerable potential of blockchain in supporting companies and industries as they embrace their roles in the CE and seek to overcome the barriers they encounter. The findings reveal that blockchain supports the transition to the CE by facilitating decentralization, enabling smart contracting, enhancing information sharing and improvement, ensuring traceability and transparency, providing incentives, offering protection and security, and promoting value creation. However, in examining the barriers that blockchain may face in supporting companies and industries as they transition to the CE, certain challenges are highlighted. These include issues related to low scalability, insufficient funding, underdeveloped regulations, limited infrastructure support, a lack of standardization and generalization, high initial adoption costs, associated risks, and a deficiency in engagement and awareness. In conclusion, this study contributes to the existing literature by demonstrating that although barriers may pose challenges to blockchain's role in facilitating the CE transition, the benefits it offers are likely to outweigh these obstacles.

Abstract Blockchain technology is a core technology expected to play a highly instrumental role in competing with socioenvironmental challenges. The literature hypothesizes various blockchain functions for building a sustainable business ecosystem. This study unifies these diverse perspectives into an interpretive strategy roadmap that provides a holistic overview of how blockchain should be leveraged to deliver sustainability functions optimally. The study first identified the sustainability functions of blockchain through a content‐centric literature review. The study applied interpretive structural modeling (ISM) and drew on experts' opinions to model how and in which order blockchain delivers these sustainability functions. The study further drew on the ISM output and interpretive logic‐knowledge base to develop the promised roadmap. Results revealed that blockchain promotes a decentralized decision system that facilitates automation and real‐time information sharing (RIS) across supply chains. Blockchain introduces traceability and transparency into supply chain operations. These conditions offer monitoring of business operations and the development of trust across value‐chain stakeholders. These driver functions lead to value chain optimization and circularity integration into business and supply chain operations. When these necessary functional conditions are met, businesses can further draw on blockchain to promote economic and environmental aspects of sustainability through more complex functions enabling resource efficiency, cost reduction, pollution prevention, and higher profit margins. The order in which businesses can leverage these functions would define blockchain sustainability performance. Each function is uniquely valuable to sustainability, and none of them can be overlooked.

As the global population continues to grow, the enormous stress on our environment and resources is becoming impossible to ignore. A focus on producing and consuming as cheap as possible has created an economy in which objects are briefly used and then discarded as waste, featuring a linear lifecycle that creates an enormous amount of waste. The alternative to the linear economy "take-make-waste" is called the “circular economy”. Under this paradigm, materials are recycled to build new products or components that are designed and built to promote their reuse and refurbishment. This assures the continuous (re-)exploitation of existing resources, reducing the extraction of new raw materials. However, customers often reject these reused or refurbished products under the suspicion that they do not meet the same usability, safety, or performance levels of new products. In this sense, trustworthy records of historical details of refurbished products could increase consumers’ confidence in products and components of the "circular economy", prioritizing trustworthiness, reliability, and transparency. This work presents a new certification tool based on blockchain technology to guarantee trusted, accurate, transparent and traceable lifecycle information of products and their components and to generate trustworthy certificates to probe refurbished product historical details. This tool aims to enhance refurbished product visibility by creating the basis for making the circular economy a reality in any domain.

The building industry is one of the most resource-intensive sectors in industrialized countries, requiring a shift from a linear to a more sustainable circular economic model. Nevertheless, there are several major challenges, such as the management of information regarding used materials and products, the lack of cross-sector documentation tools, and sales operations for implementing a dynamic circular economy in the building industry. To overcome these challenges, blockchain technology for documentation, tracing used materials and products, and the use of multi-criteria decision-making approaches for the ranking and selection of optimal used materials and products have emerged as crucial facilitators, with the potential to address the technological, organizational, environmental, and economic requirements. The purpose of this study is to develop a theoretical framework of a digital platform ecosystem for implementing a dynamic circular economy in the building industry through the integration of blockchain technology and a multi-criteria decision-making approach built upon their synergy. The priority order of two alternatives of used materials and products was determined according to the AHP method, leading to selection of the most sustainable alternative. This research study contributes to dynamic circular economies by (1) facilitating cross-sector information transparency and the tracing of used materials and products from their sources to their end-of-life stages and through (2) the ranking and selection of used materials and products based on their overall properties.
