Bi-objective risk-averse facility location using a subset-based representation of the conditional value-at-risk
Najmesadat Nazemi, Sophie N. Parragh, Walter J. Gutjahr
For many real-world decision-making problems subject to uncertainty, it may be essential to deal with multiple and often conflicting objectives while taking the decision-makers' ri…
Bi-objective facility location under uncertainty with an application in last-mile disaster relief
Najmesadat Nazemi, Sophie N. Parragh, Walter J. Gutjahr
Multiple and usually conflicting objectives subject to data uncertainty are main features in many real-world problems. Consequently, in practice, decision-makers need to understand…
A branch-and-Benders-cut algorithm for a bi-objective stochastic facility location problem
Sophie N. Parragh, Fabien Tricoire, Walter Gutjahr
In many real-world optimization problems, more than one objective plays a role and input parameters are subject to uncertainty. In this paper, motivated by applications in disaster…
Stochastic project management: Multiple projects with multi-skilled human resources
Thomas Felberbauer, Walter Gutjahr, Karl Doerner
This paper presents two stochastic optimization approaches for simultaneous project scheduling and personnel planning, extending a deterministic model previously developed by Heime…
