Minimax Relative Regret Approach for Resilient Supply Chain Design
Résumé
Uncertain disruption risks negatively influence the performance of supply chains by reducing the facilities' capacity. Proactive and recovery strategies for building resilient supply chains have received increasing attention from academia. Therefore, in this work, we study a resilient supply chain designing problem considering the uncertain occurrence and extent of disruptions, and the stochastic demand during time periods. For the problem, a two-stage min-max relative regret robust model is developed. The first stage is to determine the optimal facility locations and investments in protection systems, and the second stage decides the recovery actions and the quantity of products transported between different facilities and customers. The objective is to minimise the worst-case total relative regret cost. Finally, a case study is conducted, and some insights are given through the results of sensitivity analysis.
