摘要
研究了指标权重信息和指标值信息不完全情况下的多指标语言决策问题·通过将决策者提供的指标权重语言信息用三角模糊数来描述,给出了基于决策者提供的指标权重语言信息的指标权重确定方法;然后,再通过将决策者提供的指标值语言信息用三角模糊数来描述,提出了基于指派问题的多指标语言决策方法,为决策者进行语言决策提供方法指导·最后,通过算例说明了方法的可行性和有效性·
The problem of multi-index linguistic decision-making is studied in such a case that the information both on index weight and on value are incomplete. Giving the linguistic information on index weights which are provided by decision-maker in terms of fuzzy triangular number, the index weight can be determined according to the linguistic information as above. Similarly, giving the linguistic information on index value which are also provided by decision-maker in terms of fuzzy triangular number, a multi-index linguistic decision-making method is put forward on assignment basis as a guide to linguistic decision-making. The feasibility and effectiveness of the method is exemplified via a computation.
