A Hybrid Recovery Strategy toward Sustainable Infrastructure Systems
https://orcid.org/0000-0001-6585-5091
The occurrence of unpredictable disruptions in infrastructure systems has urged the development of a variety of recovery strategies. Each recovery strategy follows different recovery preferences or criteria, such as the criticality of damaged components, the distances between nodes, or the probability of restoration. However, no single recovery strategy exists that is deemed to effectively recover all types of failures. Most recovery strategies are either cost-effective but time-consuming or time-efficient but expensive. To consider this discrepancy and simultaneously ensure long-term recovery sustainability, a hybrid recovery strategy with switching points is developed in this paper. Given a set of recovery strategies, the most effective combination of strategies will be selected based on the progression of the recovery stage and the overall cost. The procedure for finding the switching point between different recovery strategies within the feasible region is also explained. A case study of an extensive infrastructure networked system is presented to demonstrate the feasibility and effectiveness of the proposed hybrid recovery strategy. The proposed approach can serve as a useful decision-making tool during recovery planning in the presence of limited time, budget, and resources while aiming to achieve maximum system resilience.
