In the evolution of blockchain technology, the traditional single-chain structure has faced significant challenges, including low throughput, high latency, and limited scalability. This paper focuses on leveraging multichain sharding technology to overcome these constraints and introduces a high-performance carbon cycle supply data sharing method based on a blockchain multichain framework. The aim is to address the difficulties encountered in traditional carbon data processing. The proposed method involves partitioning a consortium chain into multiple subchains and constructing a unique “child/parent” chain architecture, enabling cross-chain data access and significantly increasing throughput. Furthermore, the scheme enhances the security and processing capacity of subchains by dynamically increasing the number of validator broadcasting nodes and implementing parallel node operations within subchains. This approach effectively solves the problems of low throughput in single-chain blockchain networks and the challenges of cross-chain data sharing, realizing more efficient and scalable blockchain applications.

In multi-criteria decision-making (MCDM), accurately quantifying qualitative data and simulating real-world scenarios remains a significant challenge, particularly in the presence of inherent imprecision and incompleteness of information. Fuzzy logic, recognized for its capacity to model uncertainty and ambiguity, emerges as a pivotal theory in decision-making processes. This study introduces an enhancement to the Defining Interrelationships Between Ranked Criteria II (DIBR II) method, employing triangular fuzzy numbers with variable confidence intervals for the determination of criteria weight coefficients-essential for assessing their significance and impact on final decisions. The enhanced method, hereafter referred to as the Fuzzy-DIBR II (F-DIBR II), is elaborated upon through a comprehensive description of its algorithmic steps, underscored by a numerical example that highlights its potential. Validation of F-DIBR II is undertaken via a comparative analysis against the traditional DIBR II approach, placing particular emphasis on its application within the Fuzzy Complex Proportional Assessment (COPRAS) framework, geared towards evaluating sustainable mobility measures. This focal point not only reaffirms the necessity of integrating fuzzy logic into the DIBR II methodology but also validates its practical applicability in addressing real-world issues. Contributions of this research extend beyond the theoretical enhancements of fuzzy theory within the MCDM landscape, offering tangible implications for the application of F-DIBR II in sustainable mobility analyses. The consistency in professional terminology throughout the study ensures clarity and coherence, aligning with the stringent standards of top-tier academic journals.

This study aims to elucidate the role of established public utility logistics in facilitating the integration of transition economies into the modern, developed world, with a particular focus on comprehensive waste management and the implementation of green logistics schemes. The research highlights the “green islands” waste collection system—networks of collection points that serve as separators for secondary raw materials from generated waste. It is demonstrated that such systems not only contribute to the optimization of public utility company costs and the selection of optimal transport routes but also play a crucial role in elevating public awareness regarding the importance of the 3R principle (Reduce, Reuse, Recycle). A significant contribution of this study lies in its demonstration of how academic knowledge can be transferred to the business sector through spin-offs, evidencing a theoretical model of green logistics schemes that can increase the total amount of secondary raw materials recovered from waste by 20% by 2030 in the City of Doboj. The research underscores the role of citizens, students, and businesses as primary waste producers in transition economies, emphasizing the effectiveness of a rewards system for conscientious waste selection at the source. Moreover, the establishment of an optimal transport route designed to support these green islands is shown to enhance the collection and recycling of valuable secondary raw materials, thereby preventing their disposal in landfills without value recovery. This innovative approach not only raises public awareness towards a more sustainable environment but also establishes a foundation for long-term environmental health. Through the lens of green logistics, this study presents a compelling model for comprehensive waste management in transition economies, advocating for practices that ensure the sustainable management of resources and contribute to environmental protection and public health.
