This methodology stands between the qualitative and the quantitative methods and helps researchers to build middle-range theories (Mjoset, 2001) from small to intermediate numbers of cases. This methodology encompasses a number of techniques including crisp and fuzzy set-theoretic qualitative comparative ...
The fuzzy set-theoretic-based model was found to be more sensitive to changes in subject level of functioning over time, to provide superior quantitative protrayals of patterns of aging, and to reflect properties of the aging process derived from other research. 展开 ...
摘要: The computation procedure of similarity between fuzzy set and crisp set is derived. The proposed similarity measure is constructed through distance measure. And our results are compared with those of关键词: distance measure fuzzy entropy similarity measure ...

This concept can be generalized to allow for various degrees or strengths of association or interaction between elements using fuzzy set theory. To advance in the study of relations fuzzy helps finding new ways to solve complex issues decisions in the social, economic and management environments (...
It deals with the problem of the logical transformation of a fuzzy set into a crisp set. Such threshold arises from the ideas of contradiction and separation, and allows us to prove that crisp sets can be structurally considered as classes of discontinuous fuzzy sets. It is also shown that ...

and pitfalls of multi-value Qualitative Comparative Analysis (MvQCA). The authors are unconvinced by the technique's distinctness from the more established crisp-set QCA (csQCA) and fuzzy-set QCA (fsQCA) variants and question its added value to configurational comparative methodology on five points...
In this paper,a set of weak separation axioms in L-fuzzy topological spaces are defined and studied by giving the concept of the crisp-degree of pseudocrisp set. 在L-模糊拓扑空间中引入准分明集的分明度的概念,在此基础上,定义了一组新的弱分离公理,即WiT3,WiT4(i=1,2,3)分离公理,它们比文...
