Integrated planning of downstream petroleum supply chain : a multi-objective stochastic approach

Pudasaini, Pramesh - In: Operations research perspectives 8 (2021), pp. 1-15

In studying petroleum supply chain networks, past studies have largely segregated three critical decision-making aspects: integrated planning, uncertainties, and multi-objective setting. This study focuses on consolidating these aspects and proposes a stochastic, multi-objective, mixed-integer...

Global optimization for the multilevel European gas market system with nonlinear flow models on trees

Schewe, Lars; Schmidt, Martin; Thürauf, Johannes - In: Journal of Global Optimization 82 (2022) 3, pp. 627-653

The European gas market is implemented as an entry-exit system, which aims to decouple transport and trading of gas. It has been modeled in the literature as a multilevel problem, which contains a nonlinear flow model of gas physics. Besides the multilevel structure and the nonlinear flow model,...

Booster Draft Mechanisms for Multi-Object Assignment

Caspari, Gian - 2022

We describe a new method — what we call booster draft mechanisms — for allocating multiple, indivisible objects among a group of individuals: Individuals take turns drawing objects from different sets — called boosters — and simply need to identify their favorite object when it’s their...
