Abstract
The simultaneous consideration of economic and environmental objectives in batch production scheduling is today a subject
of major concern. However, it constitutes a complex problem whose solution necessarily entails production trade-offs.
Unfortunately, a rigorous multiobjective optimization approach to solve this kind of problem often implies high
computational effort and time, which seriously undermine its applicability to day-to-day operation in industrial practice.
Hence, this work presents a hybrid optimization strategy based on rigorous local search and genetic algorithm to efficiently
deal with industrial scale batch scheduling problems. Thus, a deeper insight into the combined environmental and economic
issues when considering the trade-offs of adopting a particular schedule is provided. The proposed methodology is applied
to a case study concerning a multiproduct acrylic fiber production plant, where product changeovers influence the problem
results. The proposed strategy stands for a marked improvement in effectively incorporating multiobjective optimization in
short-term plant operation.
