Blockchain-based Research On Information Sharing Of Prefabricated Construction Supply Chain

In recent years,with the deepening of the concept of green development,the country has issued a series of policies and guidance documents one after another,and the volume of prefabricated buildings has become more and more massive and is in the stage of rapid development.Prefabricated construction supply chain management is not ideal,nevertheless,given the current circumstances.Additionally,the operation and administration of the entire supply chain is getting more challenging as the businesses involved in building projects diversify.An essential first step in promoting the efficient and sustainable growth of prefabricated construction as well as the transformation and modernization of the construction industry is to figure out how to address the issues of distorted information transmission,low information transmission efficiency,and delayed information in the supply chain as well as how to remove the communication and information sharing bottleneck among member enterprises.And blockchain technology,which is regarded as a cloud warehouse for storing and sharing data,provides a new application paradigm for prefabricated construction supply chain information management.In summary,this paper conducts a study on prefabricated construction supply chain information sharing on the basis of dual-chain integration.This paper first compiles and synthesizes the literature on prefabricated construction supply chains,blockchain technology,and information sharing in the construction supply chain domestically and internationally,clarifies the subject matter to be studied,and elaborates the pertinent concepts and theories.Secondly,it points out the limitations of the prefabricated construction supply chain management model at the present stage,and combines the unique features of blockchain technology such as decentralization,de-trusting,traceability and security and reliability,and puts out a brand-new concept for the blockchainbased information sharing in the prefabricated construction supply chain,complete with system architecture and operational procedures.Then,the evolutionary game theory is applied to analyze the evolutionary stabilization strategies of the participating members in the information sharing activities in the supply chain,and the Matlab software is used to numerically simulate the game model and filter out the favorable and unfavorable factors affecting the information sharing behavior of the game players.Finally,in order to enhance the enthusiasm of the participating members of the supply chain to participate in information sharing activities,the Raiffa method is used to construct an information sharing income allocation model.Then,using the supply chain income allocation rules as a guide,three correction factors are chosen to maximize the initial value of the income allocation,and the model’s logic is confirmed through the study of calculation scenarios.This study uses blockchain technology to share information about the prefabricated construction supply chain,offering a fresh viewpoint to support effective supply chain management and extending the use of blockchain technology in new construction-related applications.In addition,it combines the evolutionary stabilization strategy of information sharing game subjects and suggests a more equitable and reasonable information sharing income distribution mechanism,which acts as a catalyst for encouraging the information sharing behavior of the participating supply chain participants and offers theoretical support for achieving the sustainable development of prefabricated construction and deepening the supply chain information management.Figure [18] table [16] reference [81]...
