检验决策是否科学的标准,只能是实践,即:只能在决策实施之后才能检验。为了保证决策过程的科学性,本文提出了科学决策的九项准则。文中针对大型水电工程的基本特点,模拟专家决策的思维过程,建立了大型水电工程模糊决策专家系统,并且介绍了系统的功能和优缺点。 The criteria for testing whether a decision is scientific can only be practice, that is, it can only be tested after the decision has been implemented. In order to ensure the scientific nature of the decision-making process, this paper proposes nine criteria for scientific decision-making. In this paper, according to the basic characteristics of large-scale hydropower projects and the process of simulating the thinking of expert decision-making, an expert system for fuzzy decision-making of large-scale hydropower projects was established, and the functions, advantages and disadvantages of the system were introduced.
