Abstract
Topology optimisation techniques can redistribute given materials to their most-needed locations to generate efficient and innovative structural designs. However, these techniques are typically performed based purely on structural performance. Hence, the solutions could be of low value in specific practical applications, as they may not always satisfy all design requirements, including factors like aesthetic quality. Recently, a few studies have reported that introducing subjective preferences into topology optimisation techniques can result in more satisfying structural designs so that users do not need to passively accept the conventional optimisation results. This paper provides a brief overview of the state-of-the-art in topology optimisation techniques that consider subjective preferences. The techniques are classified into three groups based on when subjective interventions are introduced: pre-processing, post-processing and interactive processing strategies. The advantages and limitations of each group are discussed, as are the technical challenges involved in extending these new techniques. Overall, this paper aims to serve as a helpful guide for future developments of topology optimisation techniques that consider subjective preferences, hoping to create more practical and customised structural designs that better meet the needs of users.
