Resilience Strengthening Paths for Precast Production Management in Prefabricated Construction

Abstract

Disturbances are inevitable and ubiquitous in precast production, making the enhancement of production management resilience essential to maintain the production performance suffered from disturbances. However, existing studies have primarily focused on single types of disturbances and strengthened the production resilience from single views, without considering the heterogeneity of disturbances and the multiple capacities of resilience. In this paper, the precast production resilience is first deconstructed according to the temporal characteristics of disturbances, including the capacities of monitoring and alarming, resistance and absorption, emergency response and recovery, and learning and reconstruction. On this basis, the resilience strengthening model for precast production management is proposed to explore the most effective combinations of resilience capacities to respond to various disturbances. In this model, multiple disturbances with different sources, frequencies, and risk levels are considered, and the optimal resilience paths are customized for different disturbance scenarios. Finally, a case study was conducted to illustrate the application of the model. The results show that the resilience enhancement relies on the synergistic interaction among multiple resilience capacities especially for the largest damage disturbances. The capacity of monitoring and alarming is a pivotal element to prevent a wide array of disturbances, while learning and reconstruction is most effective for occasional disturbances. The findings can provide insights for disturbance management in precast production and promote the development of prefabricated construction.
