This paper presents an overview of mixed-integer nonlinear programming techniques by first
providing a unified treatment of the Branch and Bound, Outer-Approximation, Generalized …

A two‐level procedure for heat‐exchanger network synthesis problems, which is related to
structural optimization, is carried out by a simulated‐annealing procedure. The main control …

The mathematical programming approach for the synthesis of heat exchanger networks
provides a powerful, and versatile framework for the simultaneous optimization of energy …

The objective of this contribution is to propose a multilevel-hierarchical approach to the
MINLP synthesis of process flowsheets. Following a hierarchical strategy, the designer can …

A sequential franiework (LP, MILP, NLP) for Heat Exchanger Network Synthesis (HENS) is
described that reduces significantly the numerical problems caused by non-linearities …

A method for optimal retrofit design of heat-exchanger networks that do not posses control
variables in their original structures, is presented. Bypasses, as control variables, are placed …

Sequential structural and parameter optimization of retrofitted complex and energy intensive
continuous processes has been studied. A method for sequential optimization of retrofits …
