This paper addresses the winner determination problem (WDP) for TL transportation procurement auctions under uncertain shipment volumes and uncertain carrier...
BibTeX referenceNORTA for portfolio credit risk
We use NORTA (NORmal To Anything) to enhance normal credit-risk factor settings in modeling common risk factors and capturing contagion effects...

The survivorship bias in credit risk modeling is the bias that results in parameter estimates when the survival of a company is ignored. We study the statist...

In this paper we consider a version of the capacitated vehicle routing problem (CVRP) where travel times are assumed to be uncertain and statistically corre...

In the last 20 years, there has been increasing interest in using advanced simulation and optimization techniques to develop and manage mineral resources a...
BibTeX referenceStochastic optimization of long-term block cave scheduling with hang-up and grade uncertainty
The current trend of deeper and lower-grade deposits makes open pit mining less profitable. Mass mining alternatives have to be developed if mining at a si...
BibTeX referenceStochastic orebody modelling and stochastic long-term production scheduling for an iron ore deposit
For over a decade, stochastic optimization has emerged as a framework that is capable of generating a life-of-mine production schedule that increases ne...
BibTeX referenceSimultaneous stochastic optimization of production scheduling at Twin Creeks mining complex, Nevada
Twin Creeks is a gold mining complex part of Newmont's Nevada Operations. The mining complex is comprised of two open pits, Mega and Vista, external ore sour...
BibTeX reference
A mining complex is a mineral value chain that consists of multiple activities, starting from material extraction to a set of sellable products delivered t...
BibTeX reference
Short-term production scheduling in open pit mining consists of defining the extraction sequence and process allocation of mineralized material over time-sca...

In this paper, we focus on the problem that has been described in the second international nurse rostering competition: a personalized nurse scheduling prob...
BibTeX reference
This study presents a production scheduling optimization method for a mining complex, which provides a flexible long-term plan for future investments and ope...

Partially observed major minor LQG mean field game theory is applied to an optimal execution problem in finance; following standard financial models, control...
BibTeX referenceNumerical methods for stochastic dynamic programming with application to hydropower optimization
Stochastic Dynamic Programming (SDP) is a powerful approach applicable to nonconvex and stochastic stagewise problems. We investigate the impact of the form...

An exchangeable bond is a debt that is convertible into shares of a firm's equity other than the bond's issuer. We evaluate an exchangeable bond within a two...

Unlike delta-hedging or similar methods based on Greeks, global hedging is an approach optimizing some terminal criterion that depends on the difference be...
