Emil Jebek 《Mathematical Logic Quarterly》2004,50(3):295-296
Grzegorczyk's modal logic (Grz) corresponds to the class of upwards well‐founded partially ordered Kripke frames, however all known proofs of this fact utilize some form of the Axiom of Choice; G. Boolos asked in [1], whether it is provable in plain ZF. We answer his question negatively: Grz corresponds (in ZF) to a class of frames, which does not provably coincide with upwards well‐founded posets in ZF alone. (© 2004 WILEY‐VCH Verlag GmbH & Co.

A Direct Approach to Group Decision Making with Uncertain Additive Linguistic Preference Relations 总被引:5,自引:0,他引:5
Zeshui Xu 《Fuzzy Optimization and Decision Making》2006,5(1):21-32
In this paper, we study the group decision-making problem in which the preference information given by experts takes the form
of uncertain additive linguistic preference relations. We define the concept of uncertain additive linguistic preference relation,
and introduce a formula based on possibility measure for comparing two uncertain linguistic preference values. We introduce
some aggregation operators such as the uncertain linguistic averaging (ULA) operator and uncertain linguistic weighted averaging
(ULWA) operator, etc. Based on the ULA and ULWA operators, we develop a direct approach to group decision making with uncertain
additive linguistic preference relations without loss of information. Finally, an illustrative numerical example is given
to verify the developed approach. 相似文献

We prove the existence of equilibria in games with players who employ abstract (non-binary) choice rules. This framework goes
beyond the standard, transitive model and encompasses games where players have non-transitive preferences (e.g., skew-symmetric
bilinear preferences).

Pairwise linear discriminant analysis can be regarded as a process to generate rankings of the populations. But in general, not all rankings are generated. We give a characterization of generated rankings. We also derive some basic properties of this model. 相似文献

It always takes time for people to digest information and make judgments. The decision maker's preference is not always clear and stable when decision analysis and decision making are performed. In this paper, we introduce a generalized preference structure to cope with indefinite preferences. We describe its general properties, its implication on value function representation, its solution concepts, and methods for obtaining the solutions.This research has been partially supported by NSF Grant No. IST-84-18863. The authors are grateful to Dr. D. J. White for his helpful comments on a previous draft. 相似文献

We show that the axiom of choice AC is equivalent to the statement Any quotient group of any abelian group has a selector. We also show that the multiple choice axiom MC is equivalent to the assertion: Any filter
in any Boolean ring
has a well ordered filterbase.

利用夏普里值来识别导致顾客不满意的质量属性.因为夏普里值差异很小的质量属性具有高度的相关性,所以可以把具有相同或者类似的夏普里值的质量属性划分为同类属性,从而能够识别导致顾客不满意的质量属性.算例进一步验证该方法的可行性和正确性. 相似文献
