55297 然而,随着决策单元所选取投入产出指标个数的增加,决策单元之间的偏序关系可能越来越少,从而能为决策者提供的决策消息也随之减少。 However, as the decision making units selected by the increase of the number of input and output indicators, partial order relation between decision making units may be less and less, which can provide decision makers with the decision-making information is reduced.
55298 本文通过引进决策单元之间的交并运算生成了新的样本决策单元,这些决策单元与原有决策单元将构成格,且这一格关系不仅能够为决策单元的投影提供相关依据,也为决策单元的合作与竞争提供新了思路。 Based on the introduction of decision making units occurring simultaneously operations generated between the new sample decision making units, the decision-making units and the original unit will form, and the lattice relationship can not only provide evidences for decision-making unit projection, also for decision making unit of cooperation and competition to provide the new train of thought.
