Research On Quality Chain Collaborative Management Of High-speed Railway "Four Power" Construction Project Based On Blockchain

As an important component of the national economy,popular travel tools and important infrastructure,high-speed rail plays an extremely important role in China’s modernization development.With the comprehensive advancement of the national “Belt and Road” project,it also brings new opportunities for the construction and development of high-speed rail.But at the same time,higher quality is also required for high-speed rail construction projects.As an important part of the high-speed rail project,the "four power" construction project of the highspeed rail has a complicated construction process and high technical content.It is necessary to strictly implement the relevant standards and acceptance requirements,and how to ensure the quality and safety of its engineering process needs great attention.However,the current highspeed rail "Four Power" construction project has problems such as centralized management and control,mistrust of each participant and asymmetry of quality information in the traditional quality chain of the high-speed rail construction project,which prevents the effective sharing of quality information and engineering resources among the participants.The quality management among the units is relatively independent,and the effect of collaborative quality management is relatively poor.Therefore,this article takes the high-speed rail "four power" construction project as the research object,and combines the blockchain and quality chain collaborative management to build a new high-speed rail "four power" construction project quality management model to improve the lack of trust and participation of the traditional engineering quality chain subject quality management has its own problems and information is not shared,thereby improving the overall engineering quality chain operation efficiency.This article introduces the current status of the traditional quality chain of the "four power" construction project of the high-speed railway,and further analyzes the problems existing in the traditional quality chain of the "four power" construction project of the high-speed railway from the three levels of organization,project management and quality information transmission.It is concluded that the fundamental problem of the current high-speed rail "four power" construction project quality management is the mistrust among the participants and the opaque quality information sharing.On this basis,the traditional quality chain collaborative management of the high-speed rail "four power" construction project is analyzed from the vertical and horizontal dimensions,and then the blockchain is introduced to explain the suitability of the blockchain for the engineering quality chain collaborative management And advantages.Therefore,a high-speed rail "four power" construction project quality chain collaborative management model based on blockchain was constructed,and its specific application process was analyzed from the material supply quality chain of the high-speed rail "four power" construction project,with a view to improving the "four power" "It provides a reference for the quality management level of other quality chains in the project.The main research results are as follows:(1)The main problems of the traditional quality chain of the "four power" construction project of the high-speed railway are analyzed,covering three major aspects,namely organization,project management and quality information transmission,which are mainly manifested in: centralized management of engineering quality,uncoordinated quality capabilities,fragile organizational trust relationships,lack of collaborative management mechanisms,difficulty in tracing quality risk supervision,asymmetry in quality information,and insufficient quality information security are the main reasons why this paper chooses blockchain as an information technology for collaborative management.(2)Establish a quality chain collaborative management framework model for high-speed rail "four power" construction projects based on blockchain.By embedding the blockchain,the application process is analyzed from the three dimensions of the quality chain engineering main body,engineering process and information sharing,and then the quality chain collaborative management framework model of the high-speed rail "four electricity" construction project based on the blockchain is built and its operation process for analysis.(3)For the material supply quality chain in the high-speed rail "four power" construction project,the blockchain is used to analyze its quality collaborative management process,and the Stackelberg game model is used to further demonstrate the embedding of the blockchain in the high-speed rail "four power" construction.The collaborative management benefits brought by the participating entities in the project material supply quality chain provide a reference for the quality management of other quality chains in the "four power" project.
