DECISION SUPPORT MODEL USING THE ADABOOST ALGORITHM TO SELECT FORMWORK SYSTEMS IN HIGH-RISE BUILDING CONSTRUCTION

摘要

Appropriate selection of a formwork system is a crucial factor in successfully completing any high-rise building construction project. However, in practice, the selection of an appropriate formwork system has depended mainly on the intuitive and subjective opinion of practitioners with restricted experience. Therefore, in this study, a decision support model using AdaBoost is proposed to select a formwork system suitable for the construction site conditions. To validate the proposed model, the selection models AdaBoost and ANN were both applied to actual case data of high-rise building construction in Korea. The AdaBoost model showed slightly better accuracy than that of the ANN model. The AdaBoost model can assist engineers to determine the appropriate formwork system at the inception of future projects.
