Abstract: In the management of airport runway engineering projects, scientifically and reasonably arranging the construction schedule is an important factor to ensure short project duration, low cost, excellent quality, and good environment. Therefore, this article mainly conducts multi-objective optimization research on the airport runway construction schedule, including construction period, cost, quality, and environment. Firstly, based on the airport runway construction blueprint, a 3D model is established using Revit software of building information modeling (BIM), and the construction models are imported into Glodon and Project to obtain quantitative data such as costs and an initial construction schedule. Secondly, a mathematical model for optimizing the objective functions of duration, cost, quality, and environment is established, and utilizing the Matlab-GUl language, a multi-objective optimization software for airport runway construction schedule with parameter input, optimization, and result output is developed based on genetic algorithm (GA). Finally, by optimizing the construction schedule of the actual case, the effectiveness and practicality of the approach and software are verified, which serves as a basis for the design of the airport runway construction schedule
