TL;DR: In this paper, a single server two-identical unit cold standby system is analyzed and the system characteristics of interest to system designers and operations managers have been obtained using regeneration point technique in MRP.

TL;DR: In this paper, a two-unit parallel system with facilities of preventive maintenance and two types of repair, i.e., regular and occasional repair, is analyzed by using regenerative point technique to obtain various economics related measures, such as mean time to system failure, steady state availability, probability that the repairman is busy, expected number of visits by the occasional repairman and the expected profit earned by the system.

TL;DR: In this article, the probability of equipment failure due to stress exceeding built-in strength has been estimated assuming a bivariate normal stress-strength distribution, and an alternative estimator based on maximum likelihood estimates has been proposed in the case when all the five parameters are unknown.

TL;DR: In this paper, the authors deal with the cost analysis of a system having three modes (normal, partial failure and total failure) in two weather conditions (normal and stormy) and show that the repair time distribution depends upon the starting state of the repair and it does not alter with the change in weather.

TL;DR: In this paper, five newly developed models to predict reliability of human operators performing time continous tasks under stress are presented, and mean time to human error (MTTHE) expressions are obtained.

TL;DR: This paper presents a very simple and fast method based on an m-level hierarchical clustering (MHC) for network overall reliability evaluation which gives results as good as exact techniques for realistic values of link reliability.

TL;DR: Fuzzy methodology is applied to develop failure detection and safety control models for processes with ill-known mathematical model and poor accuracy of measurement results of process variables.

TL;DR: Simulation results are presented which show the superiority of the schemes over previous proposals and indicate that the nearest neighbour interconnections need not be a barrier to the desirable goal of integrating an array computer onto a whole-wafer circuit.

TL;DR: In this article, the authors considered the time to first failure of a parallel system in which the failure and repair rates of components depend on the state of the other components as well and provided sufficient conditions under which this distribution has the new better than used (NBU) and an exponential limit property.
