Resilience Enhancement for Multi-State Interdependent Infrastructure Networks

摘要

Reducing vulnerability and enhancing resilience of infrastructure networks subject to uncertain disruptions is a challenge as these networks become intensively interconnected and interdependent. This paper devotes to addressing the problem of preparedness planning of interdependent infrastructure networks. The multi-state natures of network components are taken into account to characterize the interactions between infrastructure networks. A novel two-stage stochastic programming model which is able to cope with the uncertainty associated with disruptions is proposed to effectively enhance resilience under limited budget. The proposed model is applied to an illustrative network composed of interdependent power-water distribution networks, and the results show that (i) the overall resilience of interdependent power-water distribution networks is greatly enhanced under different types disruptive events. (ii) the proposed two-stage stochastic programming model is a general model framework that is applicable to a diversity of multi-state interdependent infrastructure networks.
