| چکیده | ||
| In reliability studies, the probability $R = P(Y < X)$ is called “reliability”, and $X, Y$ are typically considered independent. However, in many applications, such an assumption may be unrealistic. In this paper, we consider the stress-strength reliability $R = P(Y < X)$ where the stress $Y$ and strength $X$ are dependent. We use a copula to describe dependence among random variables $X$ and $Y$. We obtain $R$ for several copula functions with exponential marginal and plot graphs of $R$ versus the dependence parameter to study the effect of (positive and negative) dependency on $R$. | ||
