Selecting subcontractors in projects using a multicriteria group decision model

Researchers and practitioners have taken an increasing interest in analyzing outsourcing, particularly with regard to selecting contracts. In several situations, there is more than one person who is in charge of decision processes related to outsourcing and the preferences of all those involved must be considered in an appropriate way. Therefore, this paper sets out a model for selecting subcontractors using a multi-criteria group decision aid. An application in the context of construction companies illustrates the use of the model. In order to improve the performance and quality of construction projects, it is essential for contractors to select subcontractor companies in a structured way.
