A building supply chain management method based on a 4D building information model and RFID

Abstract

The invention discloses a building supply chain management method and device based on 4D BIM and RFID. The method comprises: acquiring to-be-tested construction project information at a construction site and supplier information for providing building materials for a to-be-tested construction project from a preset 4D BIM system; Obtaining the delivery distance between the supplier and the construction site from a preset RFID system, the delivery distance being used for calculating the delivery cost of each supplier; constructing a first supply chain cost model of a construction project to be tested by considering the delivery cost of building materials, the ordering cost of the building materials, the price cost of the building materials and the on-site inventory cost of the building materials; And calculating the optimal supply chain cost of the first supply chain cost model, and selecting a supplier conforming to the construction project to be tested and a corresponding supply quantity. The method provided by the invention can effectively solve the problems of reasonable selection of suppliers and orders thereof in the CSCM and reasonable construction of the collection and distribution center, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of construction supply chain management, in particular to a construction supply chain management method and device based on 4D BIM and RFID. Background technique [0002] Supply Chain Management (Supply Chain Management, referred to as "SCM") is an integrated management idea and method. Its basic idea is to identify the interdependence between supply chains and improve the supply chain by optimizing inventory, cost performance. [0003] With the development of the construction industry, the idea of ​​supply chain management originally derived from the manufacturing industry was introduced into the construction industry, forming Construction Supply Chain Management (CSCM for short). Design and construction are separated, and its construction supply chain is discontinuous and scattered, making it difficult for construction supply chain management to be as effective as manufacturing. [0004] Therefore, it is...
