Preservation properties of stochastic orders by transformation to the transmuted-G model

Communications in Statistics - Theory and Methods, 2020
The transmuted-G model is a useful technique to construct some new distributions by adding a parameter. This paper considers stochastic comparisons in the transmuted-G family with different parameters and different baseline distributions in the sense of ...

CORES OF STOCHASTIC COOPERATIVE GAMES WITH STOCHASTIC ORDERS

International Game Theory Review, 2002
In this paper we analyze cooperative games where the worth of a coalition is uncertain and the players only know their probability distribution. The novelty of our analysis is that the comparison among the uncertain values is done by stochastic orders among random variables.

RESIDUAL STOCHASTIC PRECEDENCE ORDER

Probability in the Engineering and Informational Sciences, 2020
The aim of this paper is to introduce a new stochastic order based on the residual lifetimes of two nonnegative dependent random variables and the stochastic precedence order. We develop some characterizations and preservation properties of this stochastic order.

Cumulative measures of information and stochastic orders

, 2014
In this paper we present some known results on cumulative measures of information, study their properties and relate these definitions to concepts of reliability theory.

Stochastic ordering of order statistics

Journal of Applied Probability, 1991
If Xi, i = 1, ···, n are independent exponential random variables with parameters λ1, · ··, λ n, and if Yi, i = 1, ···, n are independent exponential random variables with common parameter equal to (λ1 + · ·· + λ n)/n, then there is a monotone coupling of the order statistics X(1), · ··, X(n) and Y(1), · ··, Y(n); that is, it is possible to construct ...

GENERALIZED STOCHASTIC CONVEXITY AND STOCHASTIC ORDERINGS OF MIXTURES

Probability in the Engineering and Informational Sciences, 1999
In this paper, a new concept called generalized stochastic convexity is introduced as an extension of the classic notion of stochastic convexity. It relies on the well-known concept of generalized convex functions and corresponds to a stochastic convexity with respect to some Tchebycheff system of functions.

Supermodular Stochastic Orders and Positive Dependence of Random Vectors

Journal of Multivariate Analysis, 1997
The supermodular and the symmetric supermodular stochastic orders have been cursorily studied in previous literature. In this paper we study these orders more thoroughly. First we obtain some basic properties of these orders.

Minimizing makespan of stochastic customer orders in cellular manufacturing systems with parallel machines

Computers & Operations Research, 2020
This study addresses a stochastic customer order production problem in cellular manufacturing systems with parallel machines. The objective is to minimize the long-run expected makespan of stochastic customer orders via proper cellular manufacturing ...

Sequential Order Statistics: Ageing and Stochastic Orderings

Methodology and Computing in Applied Probability, 2011
The authors identify conditions, on the distribution functions that underlie sequential order statistics, which yield various stochastic comparisons of the corresponding sequential order statistics. They also derive sufficient conditions under which sequential order statistics have various aging properties such as increasing failure rates, increasing ...
