Optimal Ship Fuel Selection under Life Cycle Uncertainty

Shipowners need to prepare for low-emission fuel alternatives to meet the IMO 2050 goals. This is a complex problem due to conflicting objectives and a high degree of uncertainty. To help navigate this problem, this paper investigates how methods that take uncertainty into account, like robust optimization and stochastic optimization, could be...

Stochastic Open Pit Design with a Network Flow Algorithm: Application at Escondida Norte, Chile

In the optimization of open pit mine design, the Lerchs-Grossmann algorithm is the industry standard, although network flow algorithms are also well suited, efficient, and known. The stochastic version of the conventional (deterministic) network flow algorithm is based on the use of multiple simulated realizations of the ore deposit, thus...
