Subcontractors usually help general contractors to overcome problems that related to the
need for special expertise, limitation in finances and shortage in resources. However,
selecting a good subcontractor is not a trivial task as many criteria need to be wisely
prioritized. The purpose of this research is to develop the causes and effects factors of
subcontractors’ selection using Single Valued Neutrosophic Set DEMATEL method and
Intuitionistic Fuzzy Set DEMATEL method and also compare the results obtained by the
two methods. In this research, data is collected from experts’ opinions by questionnaire
survey and phone-call interview. MATLAB software is used to obtain the causal diagram
that influenced the subcontractors’ selection. The results are then compared using the
methods. The conclusion can be drawn that DEMATEL method is the most suitable
method to find out the causes and effects factors of the subcontractors’ selection. Some
recommendations will be presented in this research.
