Risk-averse decision strategies for influence diagrams using rooted junction trees
Olli Herrala, Topias Terho, Fabricio Oliveira
This paper presents how a mixed-integer programming (MIP) formulation for influence diagrams, based on a gradual rooted junction tree representation of the diagram, can be generali…

A novel strong duality-based reformulation for trilevel infrastructure models in energy systems development
Olli Herrala, Steven A. Gabriel, Fabricio Oliveira +1
We explore the class of trilevel equilibrium problems with a focus on energy-environmental applications and present a novel single-level reformulation for such problems, based on s…

Solving influence diagrams via efficient mixed-integer programming formulations and heuristics
Helmi Hankimaa, Olli Herrala, Fabricio Oliveira +1
In this paper, we propose novel mixed-integer linear programming (MIP) formulations to model decision problems posed as influence diagrams. We also present a novel heuristic that c…
