| چکیده | ||
| In this paper, we introduce and investigate a new definition for the density function of fuzzy random variables. Then, based on this definition, we give a new viewpoint on aging properties. To do this end, the concepts of the hazard rate function and mean residual function are investigated for the Exponential fuzzy random variable. Also, we obtain the aging properties of new Exponential fuzzy random variables based on existing methods. Finally, using a practical example, we illustrate the proposed approach and show that the performance of proposed approach is better than two other existing methods. | ||
