Abstract Medical group conflict decision making is one of the dominant research problems in the field of group consensus decision making. We base the research background on the optimization of clinical diagnosis and treatment in the traditional Chinese medicine (TCM) and Western medicine, and propose a novel multi-granularity sequential three-way group conflict decision with preference degree regarding the increment of decision makers and the conflicting characteristics of the decision group. Firstly, we construct a 19-scale multi-granularity conflict preference information system, and then build a generalized conflict decision making granular computing model over this 19-scale conflict information system. Secondly, we establish a sequential three-way group conflict decision making method based on the generalized conflict decision making granular computing model. Furthermore, we define three forms of group conflict result. Meanwhile, we give the definition of preference degree, represent a quantitative presentation of the diagnosis and treatment of rheumatoid arthritis (RA) in TCM and Western medicine, conclude trisection result of preference aggregation of each level group, and design an algorithm of multi-granularity sequential three-way group conflict decisions model with preference degree. Thirdly, we apply the proposed model to an example of the clinical decision-making process of TCM and Western medicine. In addition, this paper also presents the following application work, on the one hand, we verified the validity, applicability, and scientificity of the multi-granularity sequential three-way group conflict model. On the other hand, subjective knowledge is quantitatively characterized by an abstract theoretical model, which is scientific significance of the optimization of clinical diagnosis and treatment schemes for such similar diseases, and the weakening or elimination of the conflict between traditional Chinese medicine (TCM) and Western medicine, and the deep integration of TCM and Western medicine. Finally, the research can provide an innovative way of thinking for the development of internationalization and standardization of TCM.

基于偏好度的多粒度序贯三向群体冲突决策方法中西医结合

摘要 医学群体冲突决策是群体共识决策领域的主要研究问题之一。我们基于中西医临床诊疗优化的研究背景，针对决策者的增量与偏好度，提出了一种新的多粒度序贯三向群体冲突决策。决策组的矛盾特征。首先，我们构建了一个19尺度的多粒度冲突偏好信息系统，然后在这个19尺度的冲突信息系统上构建了一个广义的冲突决策粒度计算模型。第二，基于广义冲突决策粒计算模型，我们建立了顺序三路群冲突决策方法。此外，我们定义了三种形式的群体冲突结果。同时，我们给出了偏好度的定义，对类风湿性关节炎（RA）的诊治进行了量化呈现，得出了各层次组偏好聚合的三等分结果，并设计了多粒度算法具有偏好度的序列三向群体冲突决策模型。第三，我们将所提出的模型应用于中医和西医临床决策过程的一个例子。此外，本文还介绍了以下应用工作，一方面验证了有效性、适用性，多粒度序贯三向群体冲突模型的科学性和科学性。另一方面，主观知识以抽象的理论模型进行定量表征，对于优化此类类似疾病的临床诊疗方案，弱化或消除中医药与中医药之间的冲突具有科学意义。西医，中西医深度融合。最后，该研究可为中医药国际化、标准化的发展提供创新的思维方式。这对于优化此类类似疾病的临床诊疗方案，弱化或消除中西医矛盾，实现中西医深度融合具有科学意义。最后，该研究可为中医药国际化、标准化的发展提供创新的思维方式。这对于优化此类类似疾病的临床诊疗方案，弱化或消除中西医矛盾，实现中西医深度融合具有科学意义。最后，该研究可为中医药国际化、标准化的发展提供创新的思维方式。
