摘要

This paper studies a strategic supply chain management problem of designing robust networks which perform well under both normal condition and disruptions. A mix-integer programming model which incorporates p-robust measure is presented. The objective is to minimize the total nominal cost, while setting upperbounds on relative regrets in disruption scenarios. A GA-based hybrid metaheuristic algorithm is proposed and tested. Computational results demonstrate that system robustness can be substantially improved with little increase in cost. Our solution is also less conservative compared with common robustness measures.
