One of the most important things to do when deciding on projects is to choose the right contractor. Choosing inappropriate contractors causes problems such as high delays, high costs, and poor quality of project execution. The evaluation and ranking of contractors is one of the important decisions and is one of the fundamental challenges in construction projects due to the existence of various criteria; the aim of this research is to rank contractors of Zahedan gas company using the Marcos and Copperas model. Literature and research background, interviews with experts and experts were also used to identify and determine effective criteria of the Delphi method. The 7 main criteria categories included: financial resources, executive and equipment capacity, technical and planning capacity, experience, good track record, key staff and were identified to a specialized certificate. The Shannon entropy method has been used to determine the weight of the criteria. The criteria for experience, technical capacity and planning and key employees with weights of 0.17432, 0.17136 and 0.16879 are ranked first and third respectively, with the highest weight and most important criteria for selecting contractors. The results showed that the ranking in the Marcos model has the best ranking option, the optimal performance of which is the most. Thus, the Fourteenth contractor ranked first with a value of 0.8931 and the fifteenth contractor ranked second with values of 0.8667 were also selected as the top contractors. Comparing the results of Marcos and Copras showed that both methods correspond to each other, which can also be assured of the results of the Marcos model.The possibility of considering a set of criteria while maintaining the sustainability of the method is one of the advantages of the Marcos model. Therefore, it can be used in an efficient way with simple and accurate calculations for ranking.
