 Selection of Resilient Multi-Tier Supply Portfolio: A Two-Period ApproachChapter Chapter 14 in Supply Chain Disruption Management, 2020, pp 401-423 from Springer Abstract: Abstract A two-period decision-making model is developed for selection of resilient supply portfolio in a multi-tier supply chain under disruption risks. The planning horizon is divided into two aggregate periods: Period 1, before and period 2, after the disruptive event. The resilience of the supply chain is achieved by selection ahead of time primary supply portfolio and by pre-positioning of risk mitigation inventory of parts at different tiers that will hedge against all disruption scenarios. Simultaneously, recovery and transshipment portfolios are determined for each disruption scenario and decisions on usage the pre-positioned inventory are made to minimize expected cost or maximize expected service level. Some properties of optimal solutions, derived from the proposed model provide additional managerial insights. The findings also indicate that the developed portfolio approach with an embedded network flow structure leads to computationally efficient stochastic mixed integer program with a strong LP relaxation. The major managerial insights are provided at the end of this chapter. Date: 2020 There are no downloads for this item, see the EconPapers FAQ for hints about obtaining it.
