Decision support model of lump-sum contracting projects delivery methods UMADM

The uncertainties of indicators weight and indicators measurement exist in the decision-making of lumpsum contracting project delivery methods.The types and features of lump-sum contracting project delivery methods are discussed and the evaluation index system is set up.A decision support model is produced based on IA operator and ULHA operator utilizing uncertain multiple attribute theory.Through a case study,the methods of determining the interval indicators weight and model solving are described.The model incarnates the advantages both of subjective and objective weight and is close to the decision-making practice for its loose application conditions.
