processes, in which stream flowrates and their inlet compositions and temperatures may …

Model accuracy for economic optimizing controllers: The bias update case

JF Forbes, TE Marlin - Industrial & engineering chemistry …, 1994 - ACS Publications
In many process control situations the number of independent product specifications does
not equal the number of independent manipulated variables available for process control …

Synthesis and retrofit design of operable heat exchanger networks. 1. Flexibility and structural controllability aspects

KP Papalexandri, EN Pistikopoulos - Industrial & engineering …, 1994 - ACS Publications
A systematic framework for the synthesis and/or retrofit of flexible and structurally

Flexibility analysis and optimization of chemical plants with uncertain parameters

GM Ostrovsky, YM Volin, EI Barit… - Computers & chemical …, 1994 - Elsevier
In the paper two new feasibility tests are given. The first test gives the sufficient condition of
feasibility of a design. The second test gives a sufficient condition of infeasibility of a design …

Multiperiod design optimization with SQP decomposition

DK Varvarezos, LT Biegler, IE Grossmann - Computers & chemical …, 1994 - Elsevier

problems. These problems are formulated as nonlinear optimization problems with a special …

Simultaneous incorporation of flexibility and economic risk in operational planning under uncertainty

MG Ierapetritou, EN Pistikopoulos - Computers & chemical engineering, 1994 - Elsevier
In this paper, an integrated metric is introduced with which future plan feasibility together
with the potential economic risk is assessed for two-period linear planning models. It is …

Optimisation of stochastic planning models

RL Clay, JE Grossman - Institution of Chemical Engineers …, 1994 - books.google.com
We consider the optimization of multi-period linear planning models with stochastic
parameters (eg, costs, demands, and supplies). The stochastic parameters are …

Fuzzy flexibility indices in process design

A Kraslawski, L Nyström - Computers & chemical engineering, 1994 - Elsevier
A new method of flexibility estimation is proposed. It is based on the comparison of
operational flexibility and the value quality loss function. The different forms of the quality …

Integration of Flexibility and Control in Process Design

OL Chacon-Montdragon, DM Himmelblau - Integration of Process Design …, 1994 - Elsevier
Most design or retrofit focuses on cost savings as the objective. We treat instead two
simultaneous noncompatible objectives: cost and flexibility, in the design of a process that …
