I will be involved in two talks at the Twenty-first International Working Seminar on Production Economics, February 24-28, 2020, Innsbruck, Austria. The talks are: 1) R.N. Boute, S.M. Disney and J.A. Van Mieghem, ‘Global Dual Sourcing Under Correlated Demand’, 2). T. Hosoda, S.M. Disney and L. Zhou, ‘Challenges within Closed-Loop Supply Chains: Remedies for the Conflict between Sustainability and System-wide Cost’. I will add more details here on the time and location as they become available. Hope to see you there!
