In this paper, we treat the problem of stochastic comparison of standby [active] redundancy at component level versus system level. In the case of standby redundancy, we present some interesting comparison results of both series systems and parallel systems in the sense of various stochastic...

Supplier reliability is a key determinant of a manufacturer’s competitiveness. It reflects a supplier’s capability of … suppliers improve delivery reliability. Suppliers, however, often work with multiple manufacturers and the benefit of enhanced … reliability may spill over to competing manufacturers. In this study, we explore how potential spillover influences manufacturers …

transportation. Existing traffic assignment approaches do not properly account for passenger’s expectation for transfer reliability …. In this study, the transfer reliability is explicitly defined and a multi-class user equilibrium model is established …, given which passengers choose the minimal-cost path based on their expected reliability thresholds. In particular, a path …

A redundant complex discrete system is modelled through phase type distributions. The system is composed of a finite number of units, one online and the others in a warm standby arrangement. The units may undergo internal wear and/or accidental external failures. The latter may be repairable or...

This paper analyzes a phase-type geometric process repair model with spare device procurement lead time and repairman’s multiple vacations. The repairman may mean here the human beings who are used to repair the failed device. When the device functions smoothly, the repairman leaves the system...
