Selection of resilient suppliers in the presence of supply chain disruption risks

Streszczenie:
A MIP approach with conditional value-at-risk is proposed for the optimal selection and protection of part suppliers in a supply chain with disruption risks. The protection decisions include the selection of suppliers to be fortified against disruptions and the allocation of emergency inventory of parts to be pre-positioned at the protected suppliers. The decision maker needs to decide which supplier to select for parts delivery and how to allocate orders quantity among the selected suppliers, and which of the selected suppliers to protect against disruptions and how to allocate emergency inventory among the protected suppliers. The problem objective is to achieve a minimum cost of suppliers protection, emergency inventory pre-positioning and parts purchasing and shortage, and to mitigate the impact of disruption risks. Numerical examples are presented and some computational results are reported.
