Multi-criteria optimization strategies for production chains

Abstract

The aim of this paper is presentation of some optimization strategies applicable in the optimization of multi-stage and multi-threads chain structures (linear or tree-structured, acyclic graphs) with multiple intermediate goal functions. The inspirations for this type of analysis are production chains often seen in industrial plants. Production in these plants consists of sequences of multiple units connected linearly or in tree which, at various production stages, intermediate quality criteria, related to the semi-products, may occur.
