Data-driven interactive multiobjective optimization using cluster based surrogate in discrete decision space
Tutkielma esittää klusteripohjaisen sijaismallin diskreetin päätöksentekoavaruuden dimension pienentämiseksi ja lineaaristen kokonaislukuoptimointitehtävien yksinkertaistamiseksi. Sijaismalli on suunnattu erityisesti datapohjaisten päätöksenteko-ongelmien interaktiiviseen ratkaisemiseen, sillä se yhdistää sijaismallin interaktiota
helpottavan vaikutuksen ja interaktiivisen NIMBUS menetelmän hyvän
suorituskyvyn sijaismallin tuloavaruudessa. Kehitettyä sijaismallia
ja metodia myös sovellettiin monitavoitteiseen metsätalousongelmaan
hyvin tuloksin. This thesis presents a cluster based surrogate model approach for reducing dimension of discrete decision space and so for simplifying integer linear optimization problems. The model is especially aimed for solving data-driven decision making problems interactively, as the surrogate makes interaction more seamless and the interactive NIMBUS method manages well within the product space of the surrogate. The developed cluster based surrogate and method were also applied for a Boreal Forest management problem with promising results.

Data-Driven Interactive Multiobjective Optimization Using a Cluster-Based Surrogate in a Discrete Decision Space
Hakanen, Jussi; Malmberg, Jose; Ojalehto, Vesa; Eyvindson, Kyle (Springer, 2019)In this paper, a clustering based surrogate is proposed to be used in offline data-driven multiobjective optimization to reduce the size of the optimization problem in the decision space. The surrogate is combined with an ... -
An interactive surrogate-based method for computationally expensive multiobjective optimisation
Tabatabaei, Mohammad; Hartikainen, Markus; Sindhya, Karthik; Hakanen, Jussi; Miettinen, Kaisa (Palgrave Macmillan Ltd., 2019)Many disciplines involve computationally expensive multiobjective optimisation problems. Surrogate-based methods are commonly used in the literature to alleviate the computational cost. In this paper, we develop an interactive ... -

Chugh, Tinkle; Chakraborti, Nirupam; Sindhya, Karthik; Jin, Yaochu (Taylor & Francis Inc., 2017)A new data-driven reference vector-guided evolutionary algorithm has been successfully implemented to construct surrogate models for various objectives pertinent to an industrial blast furnace. A total of eight objectives ... -
Flexible data driven inventory management with interactive multiobjective lot size optimization
Heikkinen, Risto; Sipilä, Juha; Ojalehto, Vesa; Miettinen, Kaisa (Inderscience Publishers, 2023)We study data-driven decision support and formalise a path from data to decision making. We focus on lot sizing in inventory management with stochastic demand and propose an interactive multi-objective optimisation approach. ... -
Interactive data-driven multiobjective optimization of metallurgical properties of microalloyed steels using the DESDEO framework
Saini, Bhupinder Singh; Chakrabarti, Debalay; Chakraborti, Nirupam; Shavazipour, Babooshka; Miettinen, Kaisa (Elsevier BV, 2023)Solving real-life data-driven multiobjective optimization problems involves many complicated challenges.
