“…"Such a database can not be fake or hacked according to the developers, which gives it undeniable advantages over other Internet technologies for recording and storing information, and the blockchain technology also provides a certain structure for recording and recording data, which standardizes the execution of various operations." [8] Creating a blockchain is based on three main principles that can be used to build a digital supply chain: * distribution -data is stored by all users of the network / platform and does not require the creation of a centralized data center;…”

Managing the integrity of products and processes in a multi-stakeholder supply chain environment is a significant challenge. Many current solutions suffer from data fragmentation, lack of reliable provenance, and diverse protocol regulations across multiple distributions and processes. Amongst other solutions, Blockchain has emerged as a leading technology, since it provides secure traceability and control, immutability, and trust creation among stakeholders in a low cost IT solution. Although Blockchain is making a significant impact in many areas, there are many impediments to its widespread adoption in supply chains. This article is the first survey of its kind, with detailed analysis of the challenges and future directions in Blockchain-enabled supply chains. We review the existing digitalization of the supply chain including the role of GS1 standards and technologies. Current use cases and startups in the field of Blockchain-enabled supply chains are reviewed and presented in tabulated form. Technical and non-technical challenges in the adoption of Blockchain for supply chain applications are critically analyzed, along with the suitability of various consensus algorithms for applications in the supply chain. The tools and technologies in the Blockchain ecosystem are depicted and analyzed. Some key areas as future research directions are also identified which must be addressed to realize mass adoption of Blockchain-based in supply chain traceability. Finally, we propose MOHBSChain, a novel framework for Blockchain-enabled supply chains.

“…This is also highly relevant to data protection and legal issues to have a significant impact on the efficiency of the implementation of the approach. With the advancement of blockchain technology, it is possible that these problems could be alleviated by a reliable distributed-ledger data structure and a real-time supply chain process (Helo and Shamsuzzoha 2020). If the blockchain technology is used to develop an automated system of transshipment planning, the sharing of cost data and dynamic demands between the participants will become more transparent and proactive.…”

The challenges to coordinate material supply and dynamically changing demand always lead to construction interruptions or a considerable waste of materials on-site. Mainstream research has provided various advanced digital solutions to solve these problems; however, they have not addressed how to make reliable decisions with digital models to manage the demand fluctuations of construction materials. This study proposes a transshipment approach to enable the lateral sharing of perishable materials and optimize material allocation for a contractor's project portfolio. The transshipment approach includes two main steps. First, the daily material supply and demand data are collected from a continuously updated schedule and three-dimensional models as input for calculating unused material quantities. Second, an evolutionary optimization algorithm is used for optimizing the transshipment quantities with minimal cost. As proof of concept, the proposed transshipment approach is demonstrated by looking at a portfolio of seven building projects managed by the same contractor. The demonstration shows that the allocation of the unused materials helps to avoid waste and reduce costs from over-ordered materials by around 52%. As a result, this also leads to improved coordination between contractors and suppliers and better material flow in construction projects.
