Fuzzy representation of a limit order book as a measure of stock liquidity

Stereńczak, Szymon; Marszałek, Adam - In: Financial internet quarterly 22 (2026) 1, pp. 106-120

In this paper, we seek to ascertain whether the recently developed ordered fuzzy number (OFN) representation of a limit order book (LOB) by Marszałek and Burczyński (2024) may serve as a measure of stock liquidity. In particular, we aim to test whether this measure contains similar or distinct...

Hospital site selection based on two-phase multi-criteria group decision-making method using interval-valued Fermatean fuzzy Aczel-Alsina averaging aggregation operators

Meher, Bibhuti Bhusana; Jeevaraj S - In: Future business journal 11 (2025) 1, pp. 1-34

The interval-valued Fermatean fuzzy set theory plays an essential role in modeling the problem, which involves inadequate and imprecise information in a real-life scenario. Aggregation operators play a vital role in modeling and solving any decision-making problem. By keeping these points in...

Pricing life contingencies linked to impaired life expectancies using intuitionistic fuzzy parameters

Andrés Sánchez, Jorge de - In: Risks : open access journal 12 (2024) 2, pp. 1-33

impairments must be considered. This study proposes modelling mortality and interest rates using a generalization of fuzzy numbers … (FNs), known as intuitionistic fuzzy numbers (IFNs). Consequently, this paper extends the literature on life contingency … triangular intuitionistic fuzzy numbers (TIFNs) owing to their ease of interpretation and implementation. …
