Multiobjective optimization of multiproduct batch plants scheduling under environmental and economic concerns

Abstract

In batch process scheduling, production trade-offs arise from the simultaneous\ud consideration of different objectives. Economic goals are expressed in terms of plant profitability and productivity, whereas the environmental objectives are evaluated by means of metrics originated from the use of life cycle assessment methodology. This work illustrates a novel approach for decision making by using multiobjective optimization. In addition, different metrics are proposed to select a possible compromise based on the distance to a nonexistent utopian solution, whose objective function values are all optimal. Thus, this work provides a deeper insight into the influence of the metrics selection for both environmental and economic issues while considering the trade-offs of adopting a particular schedule. The use of this approach is illustrated through its application to a case study related to a multiproduct acrylic fiber production plant,\ud special attention is put to the influence of product changeovers.Peer ReviewedPostprint (published version

Multiobjective Optimization Applied to the Integration of Polyamide and Cellulose Acetate Reverse Osmosis Membranes in Hybrid Cascades for Ultrapurification of Wet Chemicals

“…The solutions were obtained via epsilon constraint method, which tackles multiobjective optimization problems by solving the corresponding series of single objective subproblems, where all objectives but one are transformed into constraints. 33 After the analysis of the results showed in Figure 7, it can be observed that the hybrid configuration was better than the CA cascade for the entire studied safety factor range, from 5.5 to 15. Besides, the hybrid system can compete with the two-stage PA cascade: for SF values higher than 6.08, the economic profit of this PA cascade became lower than the one obtained by the hybrid cascade.…”

Parametric Solution Algorithms for Large-Scale Mixed-Integer Fractional Programming Problems and Applications in Process Systems Engineering

“…Cyclic scheduling problems can be formulated as a mixed-integer linear fractional programming (MILFP) problem by optimizing the productivity, or as a mixed-integer quadratic fractional programming (MIQFP) problem if the objective function involves the trade-off between inventory and setup cost (Chu and You, 2012). Another MIFP application is optimization for sustainability , such as sustainable or environmental-conscious scheduling of batch processes (Capón-García et al, 2010) and the functional-unit based life cycle optimization . The third application field is on the optimization for return rate, such as return on investment (Bradley and Arntzen, 1999).…”

Fast optimization algorithms for large-scale mixed-integer linear fractional programming problems

“…A general form of MILFP problem is given as the following problem (P): MILFP models are widely applied to address a variety of problems, ranging from manufacturing, cyclic production, life cycle optimization, supply chain retrofit, finance, etc. [2][3][4][5][6][7][8][9][10][11][12][13]. MILFP problems are nonconvex MINLP problems and challenging to globally optimize due to its combinatorial nature and the pseudo-convexity of the objective function [14].…”
