Multicriteria modelling and decision engineering of a chemical extrusion process

In the optimisation of industrial processes, decision-makers are often confronted with multi-objective problems. For example, in manufacturing it is often necessary to optimise many conflicting objectives, subject to market constraints. Using the concept of Pareto dominance, we present a multi-objective optimisation procedure that yields an optimal zone containing the solution. Pair-wise points are compared, and non-dominated points are collected in the Pareto region. Then a ranking is established and the decision-maker selects the first-best solution. Finally, we give an application of our procedure to the chemical engineering process of manufacturing cattle feed.
