中文摘要：

在直觉模糊有序加权几何（IFOWG）算子的基础上进行改进，发展出新的集成算子，把它命名为D-IFOWG算子。通过证明，D-IFOWG算子依然良好地保留了原先的算子性质，并且这种改进方式有利于弥补原先单个属性占主导地位，其他属性被忽略的缺陷，能够更加全面地考虑属性指标选出合理方案。文中引入线性偏差：实际的海洋气候影响海军装备的综合值与指挥官主观偏爱的差距，使偏差尽可能的小从而确定影响因素的权重，而不是简单的主观赋权。最后，应用D-IFOWG算子于海军装备选择，进一步说明该算子的可行性与实用性。

英文摘要：

A new integrated operator based on the intuitionistic fuzzy ordered weighted geometric(IFOWG)operator is de-veloped,which is named as D-IFOWG operator.The D-IFOWG operator has still retained the properties of the original operator,made up for the defects that the single attribute dominates while other attributes are ignored,and considered the attribute indexesmore comprehensively so that a reasonable scheme can be selected.The linear bias is introduced in this paper because the actu-al marine climate affects the deviation between the overall value of the navy equipment and subjective preference of the com-mander,which can reduce the deviation as much as possible so as to determine the weight of the impact factors,rather than sub-jective weighting.The D-IFOWG operator has been applied to the selection of navy equipment,which further shows the feasibili-ty and practicability of the operator.
