Designing Sustainable Supply Chains in the Energy-Water- Food Nexus by the P-graph Methodology

Autor: I. Heckl, H. Cabezas, F. Friedler

Publikováno v: Chemical Engineering Transactions, Vol 45 (2015)

The P-graph or process graph framework is both a representation and a methodology that can be shown to be extremely useful as a modelling tool in various areas. P-graphs are directed bi-partite graphs that give an unambiguous representation of any pr

Solving a Separation-Network Synthesis Problem by Interval Global Optimization Technique

Autor: A.G. Szlama, K. Kalauz, B. Bertok, I. Heckl

Publikováno v: Chemical Engineering Transactions, Vol 29 (2012)

A new solution technique is proposed here for a specific kind of separation-network synthesis (SNS) problem, using Branch-and-Bound (B&B) framework and linear programming (LP). The suggested method determines effectively the structure and flowrates o
