A Status Report on Conflict Analysis in Mixed Integer Nonlinear Programming
, 2019 Mixed integer nonlinear programs (MINLPs) are arguably among the hardest optimization problems, with a wide range of applications. MINLP solvers that are based on linear relaxations and spatial branching work similar as mixed integer programming (MIP ...

Disjunctive Cuts for Nonconvex MINLP [PDF]
, 2011 Mixed Integer Nonlinear Programming (MINLP) problems present two main challenges: the integrality of a subset of variables and nonconvex (nonlinear) objective function and constraints. Many exact solvers for MINLP are branch-and-bound algorithms that compute a lower bound on the optimal solution using a linear programming relaxation of the original ...

Business Strategy and the Environment, EarlyView.ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Chemie Ingenieur Technik, EarlyView.Mechanical vapor recompression integration in distillation is analyzed, focusing on feed preheating and column pressure drop. Binary methanol–water and benzene–toluene separations are studied to identify optimal designs, which are further assessed in a bioethanol vacuum distillation sequence regarding energetic, ecological, and economic performance ...

Energy Flexibilization and Demand Response for a Novel Decentralized Power‐to‐Methanol Process
Chemie Ingenieur Technik, EarlyView.This study presents the results of an optimization framework for the scheduling of a Power‐to‐methanol process coupled with an electrolyser, renewable energy sources and a battery. The optimal dynamic operating schedule is computed with different configurations and boundary conditions, showing the advantages of flexible operation.

An Algorithm for Calculating Gas Transmission System Optimal Stationary Mode [PDF]
E3S Web of Conferences, 2019 In this paper, we consider the problem of calculating the optimal stationary mode of the gas transmission system. The maximum throughput of the gas transmission system was used as optimization criterion.
