Purpose: This study seeks to assess the significant effects of blockchain, as a new decentralized technology, in waste reduction and performance improvement of Freight Transportation Management Systems (FTMS).Methodolog: The network analysis technique is used as one of the most valid multi-criteria decision-making models. We developed this model in four levels with four main criteria of performance wastes (including cost, time, trust and security and safety), and fourteen sub-criteria, considering the blockchain technologies in four areas of digital infrastructure, visibility, transparency, and smart contracts.Findings: Findings indicate that each of these technologies, individually and collectively, has reduced the waste of road freight management systems. The digital infrastructure technology reduced time and cost waste by 46.44% and 53.56%, respectively. Visibility has reduced 23.99%, 22.30%, and 53.71% of the wastes of cost, time, and safety, respectively. The transparency technology has influenced time and trust and security by 22.63% and 77.37%, respectively, and smart contracts affected the two above waste categories by 88.81% and 11.19%, respectively. The most effective wastes were identified as transportation costs, control costs, transparency in providing information, control of product conditions, and driver monitoring.Originality/Value: This study identified the most crucial road freight transport wastes and made it possible to determine priorities in various areas of blockchain technologies for future investment to improve the FTMS performance, and the findings of this study might be a starting point for future studies in this context.

Purpose: Today, the advent of blockchain technology has changed the way businesses do business, the size and scope of different organizations. One of these areas is the supply chain, which has many stakeholders, and blockchain, with its unique features, effectively responds to the various challenges in this area. Implementing this technology, like other technologies, has many challenges. Hence, these challenges must be carefully identified and analyzed to minimize their adverse impacts to use this technology effectively. In this regard, the present study aims to identify and prioritize the challenges of implementing blockchain technology in the supply chain based on the Bayesian BWM as one of the newest multiple attribute group decision-making methods.Methodology: At first, after reviewing the research literature, the challenges were identified. Then, the Bayesian BWM method determined the importance of these challenges in the case study.Findings: The results showed that security, technical and organizational challenges are the most important challenges for the company in implementing this technology, respectively. Also, among all sub-indicators of research challenges, poor scalability, privacy/confidentiality of the information, and cyberattacks have the most importance, respectively.Originality/Value: This study studied the challenges of implementing blockchain technology as a new technology in supply chains using one of the newest multiple attribute group decision-making methods (Bayesian BWM). Based on the research results, practical and research suggestions were presented
