This paper attempts to discuss a random fuzzy renewal process based on random fuzzy theory. The interarrival times are characterized as nonnegative random fuzzy variables which is a more reasonable consideration in the real world. Under this setting, the rate of the random fuzzy renewal process is discussed and a random fuzzy elementary renewal theorem is presented. Furthermore, the expected value...
In this paper, some latest results on uncertain renewal processes including fuzzy renewal process, fuzzy renewal reward process are introduced. And then the application of these results in fuzzy block replacement policy is provided. In order to solve the model, a simultaneous perturbation stochastic approximation (SPSA) algorithm based on fuzzy simulation technique is designed to search the optimal...
