Combinatorial integral approximation
Sager, Sebastian; Jung, Michael; Kirches, Christian - In: Computational Statistics 73 (2011) 3, pp. 363-380
a novel approach that is based on a decomposition of the MINLP into a NLP and a MILP. We discuss the relation of the … MILP solution to the MINLP solution and formulate bounds for the gap between the two, depending on Lipschitz constants and … the control discretization grid size. The MILP solution can also be used for an efficient initialization of the MINLP …

Stabilizer-based symmetry breaking constraints for mathematical programs
Liberti, Leo; Ostrowski, James - In: Journal of Global Optimization 60 (2014) 2, pp. 183-194
Mathematical programs whose formulation is symmetric often take a long time to solve using Branch-and-Bound type algorithms, because of the several symmetric optima. A simple technique used in these cases is to adjoin symmetry breaking constraints to the formulation before solving the problem....

Hydrogen distribution in the refinery using mathematical modeling
Kumar, A.; Gautami, G.; Khanam, S. - In: Energy 35 (2010) 9, pp. 3763-3772
The increased requirement of hydrogen in the refinery is fulfilled by proper distribution of available hydrogen in the refinery, using additional hydrogen production system and by importing. Amongst these options first one is cost effective as no addition source is required. Thus, the present...
