TL;DR: This research applies robust optimization (RO) to the problem of locating facilities in a network facing uncertain demand over multiple periods and shows that both the box and ellipsoidal uncertainty cases can provide small but significant improvements over the solution when demand is deterministic and set at its nominal value.

TL;DR: In this article, the authors study the interplay of demand and supply uncertainty in capacity and outsourcing decisions in multi-stage supply chains and find that greater supply uncertainty increases the need for vertical integration while greater demand uncertainty increases reliance on outsourcing.

TL;DR: This work proposes a single-period inventory modelling framework with two ordering opportunities that reflects updated demand information and potentially capitalizes on supply chain flexibility, and considers two complementary forms of flexibility: quantity flexibility in production and timing flexibility in scheduling.

TL;DR: In this article, a two-period supply contract with order adjustment by the buyer is analyzed and the optimal behavior of the buyer under such a contract, both in determining the initial order quantities and in subsequently adjusting the order.

TL;DR: In this paper, the authors consider two models of labor supply uncertainty, termed productivity and availability uncertainty, and study how each affects the nature of the contracts formed, finding that in the case of productivity uncertainty, it is possible to construct a contract that coordinates the firm and agency hiring in an optimal way.
