Abstract:
When designing a supply chain network, one of the most crucial decisions is to locate facilities. Considering facility disruption risks during the design phase helps to construct a supply chain network that effectively balances the efficiency and robustness. The reliable facility location problem extends the classical uncapacitated facility location problem by considering random facility disruptions. In this talk, we present a cutting plane algorithm that solves the reliable facility location problem with a general disruption distribution, i.e., heterogeneous failure rates and correlated failures. In addition, a distributionally robust stochastic programming model along with a hybrid cutting plane – column generation algorithm is presented. The computational results show that the cutting plane algorithm not only outperforms the best known algorithm in the literature that solves uncorrelated disruptions, but also efficiently solves moderate sized problem with correlated disruptions.
