slide18

NEW PROJECTS in Process Integration

1. HENs revamp design

·important for industry and of scientific significance

·highly combinatorial  GA approach applied

the approach and computer program accomplished recently - PhD

Thesis of Mr Bochenek  

(but also a more conventional tools – LP + MILP following Asante’s concepts)

slide19

1. WATER NETWORKS (MASS EXCHANGE NETWORKS)

Results to date:

Solution method for water networks with reuse and regeneration by Adaptive Random Search Optimization

(poster at the Forum)

slide20

STOCHASTIC OPTIMIZATION

AIM:

to DEVELOP GENERAL-PURPOSE SOLVER for MINLP problems

 RESULTS TO-DATE: SOLVER OPTI-STO

(coded in C++ with modelling system)

Two stochastic optimization approaches available:

1.Adaptive Random Search (ARS)

2.Simulated Annealing (SA)

slide21

ad. ARS:

·based on Luus-Jaakola (LJ) algorithm

·modifications

a) mechanism for discrete variables  MINLP

R. Bochenek, J. Jeżowski, G. Poplewski, A. Jeżowska: Studies in Adaptive Random Search Optimization for MINLP Problems, Comput. Chem. Eng Suppl., 1999, S483-486

b)others aimed at robustness of optimization, e.g. for highly multimodalproblems

J. Jezowski and R. Bochenek, Experiences with the use of LJ algorithm and its modifications for solving chemical engineering problems, to appear in “Recent Developments in Optimization and Optimal Control” by Rein Luus (editor)

slide22

SHORT SUMMARY on experiences with ARS:

·robust for nonlinear NLP/MINLP problems

·easy to use – discontinuities, logical conditions, min-max

·limitations: number of variables, esp. of discrete type

ad. SA:

Simplex (as local optimizer) + SA framework

(concept developed by Press&Teukolsky and, later, applied in M-SIMPSA proceduredeveloped by the team of Prof. Salcedo from Portugal)

slide23

Brief characteristic:

·it is not as robust as ARS (simplex degeneration sometimes occur)

·faster than ARS (usually)

Genetic/evolutionary algorithms

·separate program (at present)

·tests are carried out to find proper parameter settings

·novel selection algorithm applied
