The Mean Residual Lifetime and Mean Past Lifetime of k-out-of-n Structures at the System Level

چکیده
In this paper we summarize some recent results on mean residual lifetime (MRL) and the mean past lifetime (MPL) of a k-out-of-n structure at the system level. In section 2, it is assumed that in a k-out-of-n system all the components of the system are working at time t. Under this condition, the MRL of the system is de ned and several properties of that are derived. In section 3, under the assumption that system has failed at time t the MPL of the components of the system is de ned and some of its properties are given.

THE MEAN RESIDUAL LIFETIME OF PARALLEL SYSTEMS WITH TWO EXCHANGEABLE COMPONENTS UNDER THE GENERALIZED FARLIE-GUMBEL-MORGENSTERN MODEL
The parallel systems are special important types of coherent structures and have many applications in various areas.In this paper we consider a two-exchangeable-component parallel system for the Generalized Farlie-Gumbel-Morgenstern (Generalized FGM) distribution. We study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...
متن کاملThe Lifetime Behavior of a New Discrete Time Mixed $delta$-shock Model
In this study, a mixed $delta$-shock model with discrete-time is defined by combining $delta$-shock and extreme shock models. In this model, a system with multiple states fails in two ways: first, when k interarrival times between two consecutive shocks with magnitude larger than the critical threshold $gamma$ are in $[delta_1, delta _2], delta_1 < delta _2$; and second, when the interarrival t...
متن کاملMEAN RESIDUAL LIFETIMES OF CONSECUTIVE-k-OUT-OF-n SYSTEMS
In this paper we study reliability properties of consecutive-k-out-of-n systems with exchangeable components. For 2k ≥ n, we show that the reliability functions of these systems can be written as negative mixtures (i.e. mixtures with some negative weights) of two series (or parallel) systems. Some monotonicity and asymptotic properties for the mean residual lifetime function are obtained and so...
متن کاملDynamic Bayesian Information Measures
This paper introduces measures of information for Bayesian analysis when the support of data distribution is truncated progressively. The focus is on the lifetime distributions where the support is truncated at the current age t>=0. Notions of uncertainty and information are presented and operationalized by Shannon entropy, Kullback-Leibler information, and mutual information. Dynamic updatings...

In this study phenotypic and genetic factors affecting the reproductive efficiency of Lori-Bakhtiari ewes were determined using 8202 reproductive records of 2478 ewes collected at Shooli research station in the southwestern part of Iran (Shahrekord) during 1989 to 2012. Reproductive efficiency over all consecutive lambing opportunities were calculated by adding the total reproductive efficiency...
