Multi-agent information collaboration method for prefabricated supply chain of prefabricated building

Abstract

The invention relates to the field of prefabricated buildings and supply chains, in particular to a multi-agent information collaboration method for a prefabricated supply chain of prefabricated building. Utilizing blockchain techniques, the method comprises the following steps: a peer-to-peer network (Peer-to-Peer System) taking a prefabricated supply chain multi-party participant of a prefabricated building as a network node is constructed; an intelligent contract algorithm based on supply chain operation transaction is provided; it is ensured that actual operation of each node can be executed only after authorization of the benefit-related nodes is obtained; meanwhile, an intelligent contract is called to change component information in the shared account book; account book informationof other nodes in the same channel is synchronously updated in real time; therefore, real-time sharing of prefabricated part state information among different participants and privacy protection amongdifferent competition units are guaranteed, progress coordination among multiple prefabricated part production factories, factories and construction sites is achieved, and on-time delivery and information traceability of prefabricated parts of prefabricated buildings are achieved.

[0002] Prefabricated buildings are the only way for my country's construction industrialization and an important measure to promote supply-side structural reform and new urbanization development. However, in the actual promotion and application, there are serious disadvantages in the prefabricated supply chain, such as information islands, poor information traceability, and poor real-time performance. , making it difficult to give full play to the inherent "low cost, high efficiency" advantages of prefabricated buildings

Although advanced technologies such as the Internet of Things and information management systems are currently used to promote prefabricated component information collaboration, the prefabricated supply chain involves multiple participants, and the management software between different participants has problems such as semantic mismatch and information incompatibility, which is difficult to achieve. Component information is shared and coordinated in multiple stages, multiple subjects, and within the entire supply chain, resulting in asynchronous information between component factories and construction sites, and between different component factories, resulting in delayed delivery of prefabricated components, delays in construction schedules, low efficiency, and increased costs.

[0003] As an emerging technical means, blockchain technology is currently mainly used in the financial industry, and the existing blockchain technology application can cause the privacy information of similar competing units to be exposed while realizing information collaboration.
