Abstract

The construction industry is a pillar industry of the national economy and has an important impact on social and economic growth. The building material supply chain is an important part of the construction industry and the foundation for the smooth progress of construction projects and quality assurance. Accurate performance evaluation of building material supply chain is an effective means of supply chain management. Due to the characteristics of building material supply chain, there are still many problems in its performance evaluation. On the one hand, the traditional supply chain performance evaluation indicators are relatively single, which cannot fully reflect the internal and external comprehensive performance levels of the supply chain. It is necessary to build a performance evaluation indicator system based on the supply process. On the other hand, the information distribution asymmetry and authenticity problems in the building material supply chain increase the cost of additional data collection and verification during performance evaluation, and at the same time affect the authenticity and accuracy of the supply chain performance evaluation results. As an emerging information technology, blockchain has the characteristics of decentralization, traceability, authenticity and intelligence, and it has a good fit with the problems existing in the performance evaluation of building materials supply chain.

In response to the above problems, this paper firstly builds a framework of comprehensive evaluation indicators based on the supply chain of construction materials based on the supply chain operation reference model and the balanced scorecard model, and selects specific indicators through the literature review method to construct the construction material supply chain performance indicators Finally, combining the analytic hierarchy process and the entropy weight method, the weight of each index is determined by the combined weighting. On this basis, combined with blockchain technology, a construction material supply chain performance information management scheme based on alliance chain and an automatic performance evaluation scheme based on smart contracts are proposed. It focuses on the on-chain process of the evaluation information in the practical Byzantine consensus algorithm, the development process of the performance evaluation smart contract, and the realization of automatic performance evaluation. Finally, this paper designs a building material supply chain performance management prototype system based on blockchain, and collects the steel supply chain data of a project in Caidian District for example analysis to verify the feasibility and practical value of the model. The rebar supply chain makes targeted recommendations.

The performance index system of building material supply chain proposed in this paper improves the evaluation system of supply chain performance and provides theoretical support for enterprises. The automatic performance evaluation model based on blockchain reduces the cost of evaluation and ensures the authenticity of evaluation information. However, this research Only realize the automation of the evaluation process, and further research on how to realize the automation of the whole process from data collection to performance evaluation can be further studied in the future.
