A Value-at-Risk (VaR) based fuzzy random facility location model (VaR-FRFLM) is… (More)

The objective of this paper is to study facility-location problems in the presence of a hybrid uncertain environment involving both randomness and fuzziness. A two-stage fuzzy-random facility-location model with recourse (FR-FLMR) is developed in which both the demands and costs are assumed to be fuzzy-random variables. The bounds of the optimal objective… (More)

—In real-world regression analysis, statistical data may be linguistically imprecise or vague. Given the coexistence of stochastic and fuzzy uncertainty, real data cannot be characterized by using only the formalism of random variables. In order to address regression problems in the presence of such hybrid uncertain data, fuzzy random variables are… (More)

WRKY TFs belong to one of the largest families of transcriptional regulators in plants and form integral parts of signaling webs that modulate many plant processes. BcWRKY46, a cDNA clone encoding a polypeptide of 284 amino acids and exhibited the structural features of group III of WRKY protein family, was isolated from the cold-treated leaves of Pak-choi… (More)

—In this paper, using Value-at-Risk, a new fuzzy portfolio selection model named VaR-FPSM is proposed. The Value-at-Risk is the measure of risk, which describes the greatest loss of an investment with some confidence level. When security returns are same kind of fuzzy variable, we derive two crisp equivalent forms of the VaR-FPSM. Furthermore, in general… (More)
