Genetic Algorithm Based optimization of Construction Site Layout of Prefabricated Buildings

Taking the prefabricated building construction site layout as the research object, combined with the concept of green construction, the BIM model of prefabricated building construction site layout is constructed by using the parametric modeling method based on genetic algorithm. According to the specific requirements of the prefabricated building construction site, considering the use of recycled concrete aggregate, and making full use of the characteristics of BIM model, the constraints and influencing factors of prefabricated building construction site layout are transformed into quantifiable data. Based on the quantifiable data, the multi-objective function is constructed, and different layout schemes are obtained by using genetic algorithm. Then, according to the results obtained, the fuzzy selection method is used to compare and select the schemes, and the best scheme for the construction site layout of prefabricated buildings is finally determined. The experimental results show that the scheme is efficient and feasible, and can meet the construction technical requirements.
