Data-driven logistics collaboration for prefabricated supply chain with multiple factories

Abstract

Prefabricated construction is increasingly replacing traditional methods due to its higher productivity, superior quality, and shorter construction time. This paper aims to optimize production and logistics collaboration within a three-tier prefabricated supply chain network to reduce overall costs and enhance response efficiency. A decision model was developed that integrates factory and logistics capacity, on-site assembly sequence, and outsourcing decisions to optimize resource allocation. The model demonstrates superior cost efficiency and resource allocation effectiveness over the Earliest Due Date (EDD) method through a hypothetical case study. This result provides robust decision support for supply chain professionals, offering significant practical implications for cost reduction and resource optimization. Our findings lay a foundation for future studies on supply chain management and optimization under dynamic conditions, offering new perspectives and methodologies.
