Selecting a method for installing marine pipelines, is a major challenge for decision-makers in oil industry. In this paper, in order to choose the best method of installing marine pipelines, a new fuzzy hybrid approach is proposed. In the proposed approach, first the indices and sub-indices are determined by experts, and their weights are calculated by using fuzzy DEMATEL-ANP method. Then, by the calculated weights, and using a fuzzy multi-objective linear programming model, the best installation method is determined according to the systematic and functional constraints. To demonstrate the proposed approach efficiency, a case study has been solved by using this approach, and the result has been confirmed by the experts. The proposed approach, provides the oil industry managers with a useful tool for increasing accuracy and ease to choose the method of installation marine pipelines.
