Three-way decision making method based on probabilistic linguistic term sets and its application in medical services

中文摘要英文摘要

在决策议题变得愈加复杂的背景下,越来越多的决策制定者选择采用概率语言术语集(probabilistic linguistic term sets,PLTSs)来表达个人偏好,而非传统的精确数值方式.针对医疗服务问题的多属性三支决策(three-way decision,3WD)方法,首先提出了一种基于概率语言 Jens-en-Shannon(probabilistic linguistic Jensen-Shannon,PLJS)散度的指数相似性度量方法,克服了目前 PLTSs 中相似性度量的信息丢失问题;并创新性地引入了新型相似度公式,基于该相似度公式,利用得分函数计算各备选方案的优秀状态集,客观计算出了每个备选方案的条件概率.其次,结合得分函数构造了相对损失函数,这不仅有效融合了决策者心理偏好,而且更加精准地确定了各备选方案的期望损失.接着,依据所建立的决策规则,对备选方案进行排序,并将其划分为接受域、延迟域与拒绝域.最后,通过一个实际案例验证了该方法的有效性与可行性,并进一步通过参数敏感性分析评估关键参数变化对决策结果的影响,确保方法的稳定性与鲁棒性.

With the progress of the times,decision-making issues have become increasingly complex,and more and more decision-makers are choosing to use probabilistic linguistic term sets(PLTSs)to express personal preferences rather than traditional precise numerical methods.Furthermore,this paper focuses on a multi-attribute three-way decision(3WD)method for healthcare service problems.Specifically,first,an exponential similarity measurement method based on the probabilistic linguistic Jensen-Shannon(PLJS)divergence is proposed,overcoming the information loss issue present in current similarity measurements between two PLTSs.A novel similarity formula is innovatively introduced.Based on this similarity formula,a score function is used to calculate the excellent state sets of each alternative and objectively compute the conditional probability for each alternative.Second,by combining the score function,a relative loss function is constructed that not only effectively incorporates the decision maker's psychological preferences but also more accurately determines the expected loss of each alternative.Next,according to the established decision-making rules,the alternatives are ranked and divided into acceptance,hesitation,and rejection regions.Finally,the validity and feasibility of the proposed method are verified through a practical case study,followed by a sensitivity analysis on key parameters to assess the impact of parameter variations on decision outcomes,ensuring the stability and robustness of the method.
