Abstract Due to industrialization and informatization of the construction industry, prefabricated construction has attracted wide attention from both research and practitioner communities. In prefabricated construction, there are exacting requirements for information sharing. Also, data in a prefabricated component supply chain tend to be dispersed in design, production, transportation and other stages. In other words, such data are significantly multi-source heterogeneous. Without an effective way of participating in supply chain dynamic collaboration, decision-making at various stages and resource allocation can be extremely challenging. This paper proposes a decision support framework for prefabricated component supply chain based on ontology and multi-agent. The framework comprises the ontology layer (i.e. provides data support for the model), the agent interaction layer (i.e. serves as the communication hub to coordinate the data transmission between modules), and the agent simulation layer (i.e. simulates interaction behavior of participants, and supports decision making). Using the Shanghai Chenxiang Road Station complex project as a case study, the paper demonstrates the validity of the proposed ontology and multi-agent based decision support framework.

1 Introduction Unlike conventional on-site casting method, prefabricated components are produced in factories, which can result in significant savings in labor, raw materials and other resources (e.g. electricity), better construction quality, and being environmentally friendly. In other words, it allows the industry to move away from the labor intensive environment to component industrialization, standardization and intensity; thus, enhancing the level of development of modern construction industry integrally. Different from traditional casting construction mode, prefabricated construction has a more stringent * Vijayan Sugumaran [email protected] Juan Du [email protected] Hengqing Jing [email protected] Kim-Kwang Raymond Choo [email protected] Daniel Castro-Lacouture [email protected]
requirement for information integration. At present, there are many challenges associated with prefabricated component supply chain (PCSC), including data integration and management optimization – the focus of this paper. At the data level, data of each participant in PCSC (e.g. BIM model data of the designer, ERP system data of the producer - component supplier, RFID data, GIS data of the transporter, and spatio-temporal data of the assembler) are distributed discretely. The heterogeneity of these multisource data complicates the process in communication and collaboration of all
