C.A. Floudas F. Boukouvala

The use of deterministic global optimization methods based on analytical C2 functions is prohibitive in a large portion of engineering applications which have one or multiple of the following characteristics: (a) high computational cost which implies that the calculation of derivatives…

Global Optimization of Constrained Grey-Box Computational Problems

World Congress on Global Optimization 2015 in Gainesville, Florida

February 24, 2015

C.A. Floudas F. Boukouvala

Grey-box global optimization refers to problems for which derivatives of the objective function and/or constraints of the original model are not directly employed for obtaining the global optimum. In typical applications of grey-box optimization, derivative information is either: (1) available…

Argonaut: Algorithms for Global Optimization of Constrained Grey-Box Computational Problems

2014 AIChE Annual Meeting in Atlanta

F. Boukouvala C.A. Floudas

Constrained grey-box optimization methods do not employ derivative information of the objective function and/or constraints of the original model for obtaining the global optimum. In typical applications of the above methods, derivative information may be available but deceptive or prohibitively…

Mathematical Modeling and Global Optimization for Entire Petrochemical Planning Operations

2014 AIChE Annual Meeting in Atlanta

November 20, 2014

J. Lie F. Boukouvala X. Xiao C.A. Floudas

In the last twenty years, the petrochemical industry has succeeded by creating markets and supplying them with suitable products used to create goods such as plastics, cosmetics, lubricants, and paints. Petrochemical production begins in a refinery that separates crude oils…

Optimization of CO2 Capture, Utilization and Sequestration (CCUS) Supply Chain Networks

2013 AIChE Annual Meeting in San Fransisco

November 08, 2013

M.M.F. Hasan F. Boukouvala C.A. Floudas

CO2 capture, utilization and storage (CCUS) is an enabling technology toward reducing CO2 emissions from stationary sources which include power plants, cement production plants, iron and steel plants, refineries, petrochemicals and gas processing plants. More than 60% of the total…
