TL;DR: In this paper, the authors proposed a fuzzy-stochastic model for the valuation of a firm equity as a European call option based on fuzzy numbers (T -numbers) and applied the Black-Scholes methodology.

TL;DR: Generalised hybrid fuzzy-stochastic binomial American real option model under fuzzy numbers (T-numbers), combination of risk and vagueness and Decomposition principle is proposed and described.

TL;DR: The paper describes methodology of dealing with financial modelling under uncertainty with risk and vagueness aspects by fuzzy-stochastic methodology and proposes an approach to modelling risks by the Value at Risk methodology under imprecise and soft conditions.

TL;DR: The approach to modelling uncertainty of the international index portfolio by the value at risk (VAR) methodology under soft conditions by fuzzy-stochastic methodology is described in the paper and that methodology described could be considered to be generalised sensitivity analysis.

TL;DR: In this paper, the authors deal with the inclusion of flexibility in financial decision-making under risk and apply a generalized approach and methodology of the flexibility modeling and valuation based on multiple choices and non-symmetrical switching costs under risk.
