Multi-level,multi-objective optimization in process engineering

This paper presents a method for feasible decomposition applicable to large-scale, non-linear, multi-objective problems. The method, comprising a multi-level problem formulation and an interactive algorithm, has distinct advantages for dealing with real-world multi-objective optimization which is carried out by hierarchically arranged units of decision-making. The method is illustrated by its application to the optimal design of a water use and treatment process system.
