The development of an offshore deepwater oilfield is a complex and risky task. One core problem in this project is the selection of a production system that maximizes oil recovery and minimizes investment and operational costs while meeting external, economic, environmental, societal and technological demands under a scenario of uncertainties. Although several studies address this problem in the literature, the proposed methods are usually complex and tailored specifically for their intended specific application, curbing its wide application. Here, we propose in beyond, a simple and effective fuzzy decision-making method that considers input uncertainties and determines the best alternative in a rational manner. By comparing the results obtained with previous studies and real scenarios, we conclude that our method can obtain the best solution in a straightforward way and in situations where other methods cannot.

海上深水油田的开发是一项复杂而危险的任务。该项目的一个核心问题是选择一种生产系统，该系统在不确定性情况下能够满足外部，经济，环境，社会和技术需求的同时，最大程度地提高石油采收率并最小化投资和运营成本。尽管在文献中有几项研究解决了这个问题，但是所提出的方法通常很复杂，并且专门针对其预期的特定应用进行了定制，从而限制了其广泛应用。在此，我们进一步提出了一种简单有效的模糊决策方法，该方法考虑输入不确定性并以合理的方式确定最佳替代方案。通过将获得的结果与以前的研究和实际情况进行比较，
