23. A new approach to the mean residual lifetime (MRL) stochastic modeling of a parallel system

Dr Reza Ahmadi (Iran University of Science and Technology)

Through incorporating a bivariate state process, this paper explores an approach to the stochastic modeling of MRL for a failure-prone parallel system operating in a random environment. The bivariate state-dependent MRL (BSDMRL) model outperforms the ordinary MRL and other state-dependent MRL models in the actual circumstance that it incorporates not only the age factor, but also two basic...

24. On the Number of Failed Components in a System and Its Application in Maintenance Models

Dr Marzieh Hashemi (University of Isfahan)

In a failed system, the number of failed components at a particular time or at the time of system failure might be useful for understanding the stochastic behavior of the system. In this talk, we investigate the role of this quantity in scheduling optimal maintenance strategies for a multi-component system. The system has different types of independent components, and the components are...

1. On the time dependent δ-shock model

Dheeraj Goyal (Indian Institute of Technology Jodhpur)

One of the most popular ways to model an impact of a random environment on system’s performance characteristics is via the external shocks that either cause certain damages or immediately result in failures. There is vast literature on this topic with respect to the relevant theoretical properties of the corresponding lifetime models as well as to the various practical applications. One of the...

25. Optimal Maintenance Models for Coherent Systems Sold with Warranty

Dr Mahdi Tavangar (University of Isfahan)

In this talk, we will consider maintenance strategies for coherent systems consisting of n components. The system is under a warranty policy with two consecutive phases under which the manufacturer’s commitment goes in two different forms. In Phase I, upon the system failure, the failed components are replaced with new ones and a corrective maintenance is performed on the whole system. If...

2. Ordering and ageing properties of sequential order statistics governed by the Archimedean copula

Tanmay Sahoo (Indian Institute of Technology Jodhpur)

In reliability theory, k-out-of-n systems play an important role as these are the basic structures of many technical systems used in real-life. While modeling these systems, we most often assumed that the failure of one component does not have any impact on the performance of the remaining surviving components. This indeed oversimplifies the modelling of such systems. Sequential order...
