In the construction sector, time, cost, and quality factors hold critical importance for the success of projects. Minimizing time, managing costs, and enhancing quality are essential elements for achieving success in many application areas. grey wolf optimization (GWO) is a natural search algorithm that has been effectively utilized in optimization problems in recent years. GWO offers an optimization approach that mimics the interaction between leader wolves, sub-leader wolves, and hunting wolves. The aim of this study is to enhance the performance of GWO algorithm in solving multi-objective construction time–cost–quality problems by integrating archive and grid mechanisms. The archive serves as a data structure to preserve diversity within the solution population and store better solutions. On the other hand, the grid mechanism aims to improve the search process by dividing the solution space. This study evaluates the performance of the GWO algorithm by addressing multi-objective construction time–cost–quality problems with 7 and 13 activities. The results obtained demonstrate that GWO algorithm outperforms genetic algorithm (NSGA-II). These findings highlight the impact and advantages of the GWO algorithm in solving multi-objective construction time–cost–quality optimization problems. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.Springer Science and Business Media Deutschland GmbH2024Conference Objecthttps://rdlopen.rawdatalibrary.net/r/ebyu/11684https://doi.org/10.1007/978-981-97-4654-5_1978-981974653-81876-1100enLecture Notes in Electrical Engineeringinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/conferenceObjecthttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/11684
