Hybrid model generation for superstructure optimization with Generalized Disjunctive Programming
(Pergamon-Elsevier Science Ltd, 2021-11)
We propose a novel iterative procedure to generate hybrid models (HMs) within an optimization framework to solve design problems. HMs are based on first principle and surrogate models (SMs) and they may represent potential ...
A disjunctive programming model for superstructure optimization of power and desalting plants
(Elsevier Science, 2008-03)
In this paper, a new formulation based on disjunctive programming to model the superstructure of alternative configurations for the synthesis, design and analysis of combined cycle power and desalination plant recently ...
Effect of Superstructure Materials and Misfit on Stress Distribution in a Single Implant-Supported Prosthesis: A Finite Element Analysis
(Lippincott Williams & Wilkins, 2010-05-01)
This finite element analysis study evaluated the optimal material combination for the superstructure of single implant-supported prosthesis with different fit patterns. Two models of a two-dimensional finite element analysis ...

Superstructure-based optimization of vapor compression-absorption cascade refrigeration systems
(Molecular Diversity Preservation International, 2020-04-10)
A system that combines a vapor compression refrigeration system (VCRS) with a vapor absorption refrigeration system (VARS) merges the advantages of both processes, resulting in a more cost-effective system. In such a cascade ...
Integrated Process Design Optimization Accounting for Co-Digestion of Sludge and Municipal Solid Waste
(Elsevier, 2017-10)
This work presents an optimization model for the integrated design of waste treatment facilities, accounting for co-digestion of sludge and municipal solid waste. The superstructure of alternatives includes anaerobic ...
Optimal design of ethylene and propylene coproduction plants with generalized disjunctive programming and state equipment network models
(Pergamon-Elsevier Science Ltd, 2021-06)
In this work, we propose a superstructure optimization approach for the optimal design of an ethylene and propylene coproduction plant. We formulate a superstructure that embeds ethane and propane steam cracking technologies, ...
Design and operation issues using NLP superstructure modelling
(Elsevier Science Inc., 2006-09)
Till present, models that determined batch plants configurations in the chemical process industry resorted to models with binary variables to represent the different admissible options. This approach allowed representing ...
BISSO : Biomass Interface for Superstructure Simulation and Optimization
(MDPI, 2019)
This paper presents a web-based tool for the optimization of biomass-to-chemicals processing pathways. The tool provides a user-friendly grpahical user interface (GUI) for building a process superstructure, offers the ...
Surrogate-model based MILP for the optimal design of ethylene production from shale gas
(Pergamon-Elsevier Science Ltd, 2020-10-04)
We propose a novel algorithm for the optimal design of entire plants by refining piecewise linear surrogate models within an iterative framework. We apply this strategy to a superstructure for ethane-based ethylene production, ...
