Abstract

Optimization-based process design can be accomplished by the formulation of superstructures and the use of metaheuristics as well as deterministic optimization. This paper proposes a novel hybrid optimization approach, which combines an evolutionary algorithm (EA) and a sophisticated deterministic optimization strategy. In contrast to related approaches, the EA provides an initial superstructure, which results in a MINLP and is solved by a local deterministic algorithm. This combination ...
