提出了一种确定有限方案多目标决策权系数的新方法，该方法能合理地确定各目标间的加权系数，对决策方案和评价目标没有任何数量要求和限制，且决策结果准确、可靠、不具有主观随意性，因而适用于所有有限方案多目标决策。 A new method to determine the multi-objective decision-making weight coefficient of the limited scheme is proposed. The method can reasonably determine the weight coefficient between the targets, and does not have any quantitative requirements and restrictions on the decision-making scheme and evaluation target. The decision-making result is accurate and reliable. It is subjective and arbitrary and therefore suitable for multi-objective decision-making of all finite solutions.
