TL;DR
This paper introduces a new method to evaluate prefabricated building components using a multi-layer network model and improved topsis to identify critical nodes and improve construction management.
Contribution
A novel evaluation approach combining multi-layer complex networks and improved topsis for prefabricated construction management.
Findings
Key nodes like 'G2', 'G1', 'S24', and 'Q1' were identified as critical for component connections.
Quality issues during the construction phase are the main cause of connection problems in prefabricated components.
Critical node failure significantly reduces network cohesion and synergy in prefabricated construction.
Abstract
Prefabricated buildings face greater and different prefabricated components throughout their entire lifecycle, leading to a significant increase in management difficulty. This article proposes an evaluation method based on a multi-layer complex network model combined with an improved topsis. Firstly, by combining relevant regulations, literature, and engineering experience, the factors affecting the connection of components in prefabricated building are identified and the relationships between these factors are clarified to construct a multi-layered complex network model. Secondly, complex network theory is applied to calculate and analyze the importance evaluation indicators of the model nodes. Finally, the nodes are evaluated using the entropy weight optimization topsis method, and key nodes are selected based on the comprehensive importance evaluation value, and simulation…
