We formulate and solve a real-world shape design optimization
problem of an air intake ventilation system in a tractor cabin by
using a preference-based surrogate-assisted evolutionary multiobjective optimization algorithm. We are motivated by practical
applicability and focus on two main challenges faced by practitioners in industry: 1) meaningful formulation of the optimization
problem reflecting the needs of a decision maker and 2) finding a
desirable solution based on a decision maker’s preferences when
solving a problem with computationally expensive function evaluations. For the first challenge, we describe the procedure of modelling
a component in the air intake ventilation system with commercial
simulation tools. The problem to be solved involves time consuming computational fluid dynamics simulations. Therefore, for the
second challenge, we extend a recently proposed Kriging-assisted
evolutionary algorithm K-RVEA to incorporate a decision maker’s
preferences. Our numerical results indicate efficiency in using the
computing resources available and the solutions obtained reflect
the decision maker’s preferences well. Actually, two of the solutions
dominate the baseline design (the design provided by the decision
maker before the optimization process). The decision maker was
satisfied with the results and eventually selected one as the final
solution.

A Surrogate-assisted Reference Vector Guided Evolutionary Algorithm for Computationally Expensive Many-objective Optimization
Chugh, Tinkle; Jin, Yaochu; Miettinen, Kaisa; Hakanen, Jussi; Sindhya, Karthik (Institute of Electrical and Electronics Engineers, 2018)We propose a surrogate-assisted reference vector guided evolutionary algorithm (EA) for computationally expensive optimization problems with more than three objectives. The proposed algorithm is based on a recently developed ... -
A survey on handling computationally expensive multiobjective optimization problems with evolutionary algorithms
Chugh, Tinkle; Sindhya, Karthik; Hakanen, Jussi; Miettinen, Kaisa (Springer, 2019)Evolutionary algorithms are widely used for solving multiobjective optimization problems but are often criticized because of a large number of function evaluations needed. Approximations, especially function approximations, ... -
On Dealing with Uncertainties from Kriging Models in Offline Data-Driven Evolutionary Multiobjective Optimization
Mazumdar, Atanu; Chugh, Tinkle; Miettinen, Kaisa; López-Ibáñez, Manuel (Springer International Publishing, 2019)Many works on surrogate-assisted evolutionary multiobjective optimization have been devoted to problems where function evaluations are time-consuming (e.g., based on simulations). In many real-life optimization problems, ... -
Surrogate-assisted evolutionary biobjective optimization for objectives with non-uniform latencies
Chugh, Tinkle; Allmendinger, Richard; Ojalehto, Vesa; Miettinen, Kaisa (Association for Computing Machinery (ACM), 2018)We consider multiobjective optimization problems where objective functions have different (or heterogeneous) evaluation times or latencies. This is of great relevance for (computationally) expensive multiobjective optimization ... -
Probabilistic Selection Approaches in Decomposition-based Evolutionary Algorithms for Offline Data-Driven Multiobjective Optimization
Mazumdar, Atanu; Chugh, Tinkle; Hakanen, Jussi; Miettinen, Kaisa (IEEE, 2022)In offline data-driven multiobjective optimization, no new data is available during the optimization process. Approximation models, also known as surrogates, are built using the provided offline data. A multiobjective ...
