摘要
有限理性通常指决策者困顿于信息处理能力有限的自然状态,该状态是决策者在实际决策情境中需要面对的常态,因而有必要研究有限理性下的决策问题.多粒度粗糙集在多属性群决策分析领域的优势在于运算效率高,并能结合决策风险,然而多数基于多粒度粗糙集的多属性群决策方法并未考虑有限理性这一实际情境.以q‐RO(q‐Rung Orthopair)模糊集为背景,首先提出乐观与悲观多粒度q‐RO模糊粗糙集模型;接着在并购对象选择的背景下,依据交互式多属性决策(Portuguese of Interactive and Multi‐criteria Decision Making,TODIM)法来处理有限理性下的决策信息,发展多粒度q‐RO模糊粗糙集的最优粒度选择机制并建立相应的多属性群决策方法;最后结合并购对象选择的实际算例验证了所建立模型与方法的有效性.
Bounded rationality usually refers to a natural state that decision makers are limited to finite information processing abilities,and it is normal for them to face bounded rationality in practical decision making scenarios.Thus,studying corresponding decision making problems under bounded rationality is imperative.Multigranulation rough sets(MGRS)own two merits in the field of multi‐attribute group decision making(MAGDM),i.e.,high computational efficiencies and integrating decision risks.However,most MGRS‐based MAGDM methods fail to consider the context of bounded rationality.This paper takes q‐RO(q‐rung orthopair)fuzzy sets as the background and the concept of optimistic and pessimistic multigranulation q‐RO fuzzy rough sets is put forward at first.Then,under the context of merger and acquisition target selections,the TODIM(Portuguese of Interactive and Multi‐criteria Decision Making)method is utilized to process decision making information under bounded rationality,and optimal granularity selection schemes of multigranulation q‐RO fuzzy rough sets along with corresponding MAGDM methods are further developed.At last,a real‐life case study for merger and acquisition target selections is investigated to reveal the validity of the constructed models and methods.
