TL;DR: In this paper, a conceptual framework of profust reliability theory is developed on the basis of the fuzzy state assumption and the probability assumption, and the concept of the virtual random lifetime is introduced and a typical systems including the series system, parallel system, Markov model, mixture model and coherent system are briefly discussed within the conceptual framework.

TL;DR: In this paper, the authors proposed an algorithm that selects the optimal set of links that maximizes the overall reliability of the network subject to a cost restriction, given the allowable node-link incidences, the link costs and the link reliabilities.

TL;DR: In this paper, a general repair model based on the concept of scale transformation is investigated, where the failuretime distribution function of a repairable unit on the cycle before the repair was F(x), then after the repair it would be F(ax), where a > 1 is a scale parameter.

TL;DR: A fuzzy importance index is proposed to demonstrate the contribution of a basic event to the safety improvement of the top event in a fuzzy environment.

TL;DR: In this article, a repair replacement model for a deteriorating system is proposed, in which the successive survival times of the system are stochastically nonincreasing and form a geometric process, and the magnitude of the shock at each failure and the consecutive repair times after failure also constitute geometric processes.

TL;DR: In this paper, the mathematical theory for the point estimation of the parameters of the Burr Type XII distribution by maximum likelihood (ML) is developed for Type II censored samples and necessary and sufficient conditions on the sample data that guarantee the existence, uniqueness and finiteness of the ML parameter estimates for all possible permissible parameter combinations.

TL;DR: In this paper, the reliability of a multicomponent stress-strength system when both stress and strength are independently identically bounded by random variables is analyzed using maximum likelihood and Bayes estimators.

TL;DR: In this article, the authors proposed a first-model-validation-then-parameter-estimation approach to simplify the model validation and parameter estimation problem in software reliability analysis.

TL;DR: In this paper, the concept of reliability equivalence is extended to the case when the survival function is used as performance measure of a reliability system and reliability equivalences are calculated for a single component and for two component series and parallel systems.

TL;DR: A newly developed probabilistic model representing two units in parallel and one on standby system with critical and non-critical human error and a general formula for the system steady-state availability is developed.

TL;DR: In this paper, a model for a two-duplex unit standby system involving two types of repair is presented, where there is a single repair facility which serves the triple role of inspection, repair and replacement of a failed unit.

TL;DR: A Fuzzy Success Index Method (FSIM) is developed to estimate human reliability that can take into account the variability of human performance as well as the biases inherent within individual judgment.

TL;DR: In this article, the duality between the consecutive-k-out-of-n F and G systems was explored and the Birnbaum reliability importance of the components in an i.i.d. system was discussed.

TL;DR: In this article, the authors reviewed and discussed well established results and unsolved problems in ULSI divices, making distinction between traditional techniques (median time to failure technique and resistometric methods) and more recently developed methods (high-resolution resistometric techniques and low-frequency noise measurement), also considering the fast techniques used for metallisation testing in the industrial environment.

TL;DR: A comparison has been made with Singpurwalla-Soyer models in order to validate the proposed fuzzy software reliability model (FSRM).

TL;DR: In this paper, a cost model is developed to determine the optimal values of the number of cold standbys, the amount of warm standby, and the number repairmen simultaneously, while maintaining a minimum specified level of system availability.

TL;DR: In this paper, a theorem concerning the largest integer g m (a1,a2) and the smallest integer G m with m different representations with a 1/a2 as basis is proved.

TL;DR: In this article, the influence of the reliability of the communication line on the distribution of the number A(t) of customers in the system was studied. But the authors focused their attention in an important aspect, namely, the influence on the number of repeated orders.

TL;DR: In this paper, a review of the literature on robot safety and reliability is presented, which has been classified into three broad categories: Robot Reliability, Robot Safety and Maintenance, and General.

TL;DR: A software reliability growth model with a learning factor for imperfect debugging based on a non-homogeneous Poisson process (NHPP) and an optimal release policy is obtained for a software system based on the total mean profit and reliability criteria.

TL;DR: Reliability and availability analyses of a two unit parallel system with warm standby and common-cause failures with expressions for Laplace transforms of system state probabilities, steady state system availability, system reliability, and mean time to failure are developed.

TL;DR: In this article, the authors used the two common, alternative approaches to maximum likelihood estimation: one approach of directly maximizing the log likelihood function and another approach of solving the system of equations obtained from differentiation.

TL;DR: In this paper, a universal guideline and state-of-the-art hot-carrier effects in scaled MOSFETs are reviewed and discussed from the viewpoints of 1) DC and AC hotcarriers effects, 2) hotcarrier detrapping phenomena, 3) mechanical stress effects on hot-Carrier phenomena, and 4) hot carrier resistant device structures.

TL;DR: This paper discusses software release policies for a flexible reliability growth model based on a non-homogeneous Poisson process (NHPP) with a random life cycle and a penalty cost.

TL;DR: In this paper, the authors investigated the general repair models based on a virtual age concept and showed that the corresponding renewal process converges in some sense to a renewal process with identically distributed cycles.

TL;DR: In this article, a class of estimators is proposed for estimating the population parameter (mean) Y of the study character y, using information on an auxiliary character x, in systematic sampling of which the estimator is proposed by Swain [J. Indian Statist. Ass. 2 (213), 160,164 (1964)], Sukla [Proceedings of the All-India Seminar on Demography and Statistics, pp. 243,248. Varanasi, India (1971)] and difference estimator in systematic sample are particular cases.

TL;DR: In this paper, a bleaching and screening system (each having four subsystems) in the paper industry with three states: good, reduced, and failed is discussed, where the failure rate for each subsystem is constant while the repair rates are arbitrary.
