Track: Systems Dynamics

Abstract

Considering that contractors are one of the main pillars of construction projects and also an important factor in converting resources into the final product, it is important to evaluate and select contractors and suppliers. The selection of a contractor for construction projects is primarily based on the lowest price, but many other factors, quantitatively or qualitatively, have great importance in choosing a contractor or supplier. In this paper, taking into account the construction companies of EPC, factors affecting to the selection of contractors and suppliers and their impact on each other are considered. This review is based on the DEMATEL method and by applying this approach, affected or effected factors are used to evaluate and rank the indicators in the selection of suppliers or subcontractors. Therefore, using this method, the main contractors in construction projects do not select suppliers or subcontractors in an intellectual way, and this choice will be based on indicators.
