In this paper, we extend the mean-variance portfolio model to explicitly account for uncertainty about the estimated expected returns and/or the underlying return-generating model. We do this by first imposing an additional constraint on the mean-variance portfolio optimization program that restricts each parameter to lie within a specified confidence interval of its estimated value, and then b...
The mean-variance approach is an influential theory of decision under risk proposed by Markowitz (1952). Unfortunately, the mean-variance approach allows for violations of the first-order stochastic dominance. This paper proposes a new model in the spirit of the classical mean-variance approach but without violations of stochastic dominance. The proposed model represents preferences by a functi...
this paper presents a new formulation for warehouse inventory management in a stochastic situation. the primary source of this formulation is derived from fp model, which has been proposed by fletcher and ponnambalam for reservoir management. the new proposed mathematical model is based on the first and the second moments of storage as a stochastic variable. using this model, the expected value...
