The research employs system dynamics to model the interrelationships between key factors such as blockchain adoption, data accuracy, transaction transparency, and supply chain performance. The findings highlight that blockchain integration significantly improves demand forecasting accuracy by ensuring real-time data sharing, reducing information asymmetry, and enhancing decision-making processes. Moreover, the simulation results show that blockchain adoption can reduce forecasting errors, thereby lowering operational costs.

It is vital to identify an efficient ESC framework to enhance the competitiveness of horticultural exports.

This study develops such a framework by identifying the key dimensions and indicators of an efficient horticulture ESC using a systems approach. A scoping review was conducted with a total of 62 studies meeting the inclusion criteria. Key efficiency indicators were grouped under seven dimensions of an ESC: economic, time, management, network, innovation, market and eco-efficiency. Careful management of these domains is required to achieve an efficient ESC for perishable horticulture that can deliver on consumer satisfaction and meet sustainability outcomes. We show that management, time, and network efficiencies should be applied at every stage of ESC, whereas other efficiency dimensions are required only at certain stages. This research fills a gap in understanding efficient horticultural ESC frameworks for stakeholders such as researchers, industry bodies, growers, distributors, processors, exporters, retailers and policymakers.</div></div>","PeriodicalId":101186,"journal":{"name":"Supply Chain Analytics","volume":"10 ","pages":"Article 100112"},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As mining industry is viewed as one of the most polluting industries, it becomes apparent to rectify mining activities through the integration of sustainability into its supply chain. However, the sustainability drive must not compromise long-term economic performance. To address this issue, a case-based study is attempted in the present work to identify and analyze the drivers and barriers responsible for implementing sustainability in the supply chain of Indian mining industries. An integrated approach of the fuzzy analytical hierarchy process (F-AHP) and fuzzy decision-making trial and evaluation laboratory (F-DEMATEL) has been proposed to determine the priority and interdependency between the sustainability implementation factors. Also, sensitivity analysis has been carried out to understand the factors significantly influencing system sustainability. The study reveals that “environmental certification and government regulation” and “lack of regulations on sustainability”’ are the most crucial driver and barrier, respectively, to adopt sustainability in the Indian mining industry.

These smart contracts govern the assignment of drone-based delivery tasks, ensuring that supplies are optimally allocated and transported via the most efficient routes. The system verifies task completion and maintains a transparent record of the logistics process. The robustness of the model is validated through sensitivity analysis, while the smart contract system is confirmed through unit testing, demonstrating its reliability under varied conditions.
