Abstract

This paper presents a new extension of the hesitant fuzzy linguistic term set (HFLTS) called intuitionistic fuzzy confidence-based HFLTS that associates an intuitionistic fuzzy value (IFV) with each linguistic term. The resulting term set is termed as intuitionistic fuzzy confidence hesitant fuzzy linguistic term set (IFCHFLTS). The previous studies on the linguistic decision making have emphasized little upon the preference and non-preference for each of the linguistic terms. This information, however, is crucial in multi-criteria decision making under uncertainty. In this regard, we find IFV particularly useful for qualifying each of the linguistic terms with the agent’s degree of preference, non-preference, and hesitation values. Besides, a new aggregation operator named intuitionistic fuzzy confidence linguistic simple weighted geometry (IFCLSWG) is also proposed to fuse decision makers’ linguistic preferences. Further, the criteria weights are estimated using a new method called intuitionistic fuzzy confidence linguistic standard variance. An approach is also suggested for ranking the given alternatives by adapting VIKOR under the proposed IFCHFLTS context. Finally, the practicality and usefulness of the proposal are demonstrated through two real-world problems in green supplier selection for manufacturing industry, and medical diagnosis. The strengths and weaknesses of the proposal are also highlighted by drawing upon a comparison with similar methods.

具有模糊置信度的扩展犹豫模糊语言术语集,用于解决群体决策问题

摘要

本文提出了一种犹豫的模糊语言术语集(HFLTS)的新扩展,称为直觉模糊基于置信度的HFLTS,它将直觉模糊值(IFV)与每个语言术语相关联。所得的术语集称为直觉模糊置信犹豫模糊语言术语集(IFCHFLTS)。以前有关语言决策的研究很少强调每个语言术语的偏好和不偏好。但是,此信息对于不确定性下的多标准决策至关重要。在这方面,我们发现IFV对于用代理人的偏爱程度,非偏爱程度和犹豫程度来限定每个语言术语特别有用。除了,还提出了一种新的聚合运算符,称为直觉模糊置信语言简单加权几何(IFCLSWG),以融合决策者的语言偏好。此外,使用一种称为直觉模糊置信语言标准差的新方法来估计标准权重。还建议了一种在建议的IFCHFLTS上下文中通过调整VIKOR对给定替代方案进行排名的方法。最后,通过在制造业的绿色供应商选择和医疗诊断方面的两个现实问题,证明了该提案的实用性和实用性。通过与类似方法进行比较,还突出了该提案的优点和缺点。标准权重是使用一种称为直觉模糊置信语言标准差的新方法估算的。还建议了一种在建议的IFCHFLTS上下文中通过调整VIKOR对给定替代方案进行排名的方法。最后,通过在制造业的绿色供应商选择和医学诊断方面的两个现实问题,证明了该提案的实用性和实用性。通过与类似方法进行比较,还突出了该提案的优点和缺点。标准权重是使用一种称为直觉模糊置信语言标准差的新方法估算的。还建议了一种在建议的IFCHFLTS上下文中通过调整VIKOR对给定替代方案进行排名的方法。最后,通过在制造业的绿色供应商选择和医疗诊断方面的两个现实问题,证明了该提案的实用性和实用性。通过与类似方法进行比较,还突出了该提案的优点和缺点。该提案的实用性和实用性通过制造行业绿色供应商选择和医疗诊断中的两个现实问题得以证明。通过与类似方法进行比较,还突出了该提案的优点和缺点。该提案的实用性和实用性通过制造行业绿色供应商选择和医疗诊断中的两个现实问题得以证明。通过与类似方法进行比较,还突出了该提案的优点和缺点。
