Abstract: Multiobjective optimisation is a widely used method in the design of structure and operations of industrial processes. It makes possible to analyse several conflicting objectives which usually occur when dealing with industrial processes, such as papermaking. In this paper, different approaches to multiobjective optimisation in papermaking applications are presented based on literature survey. Literature can be divided into groups of industrially-oriented and method-based studies. However, exact divorce is difficult because some applications may be very practical but optimisation method is still developed to suit that kind of problems. Correspondingly, a detailed analyse of an optimisation method itself may be illustrated by using a detailed practical case study. Overall, it seems that multiobjective optimisation is a cost efficient and suitable tool for different purposes in the papermaking field. However, in model-based optimisation the results are as reliable as the model is. Therefore, the modelling step should get at least as much attention as the optimisation procedure. By this way, multiobjective optimisation can be effectively used to solve practical industry-based problems.
