Notice of Retraction Study of Entropy Weight Theory in EPC Owner Risk Decision

With international practice and needs of business own development, it's has become more and more common to carry out EPC project in enterprises' contract. Comparing with the traditional patterns of contract, the owners will not involve in the specific process of project in EPC model, so the decision risk of the owners is increased. Through analyzing of EPC contract model, to the ambiguity and uncertainty of risk assessment information, entropy weight theory is introduced into risk decision of EPC project. In the absence of index weight given by experts, multiple EPC schemes are evaluated and ranked sequence with risk level closeness degree effectively by the entropy weight model, and the optimum scheme is obtained definitely.
