Journal ArticleDOI
On an unreliable-server retrial queue with customer feedback and impatience
TL;DR: This system is analyzed as a process of quasi-birth-and-death (QBD) where the quasi-progression algorithm is applied to compute the rate matrix of QBD model, and a recursive solver algorithm for computing the stationary probabilities is developed.
Journal ArticleDOI
The generalized age maintenance policies with random working times
TL;DR: By introducing costs due to repairs, maintenance and replacement, the expected cost per unit time is derived as a criterion of optimality and the optimal policy that minimizes that cost is discussed analytically.
Journal ArticleDOI
Computational analysis of machine repair problem with unreliable multi-repairmen
TL;DR: This paper considers a multi-repairmen problem comprising of M operating machines with W warm standbys (spares) and proposes to use the Quasi-Newton method and probabilistic global search Lausanne method to search for the global optimal system parameters.
Journal ArticleDOI
Modeling of multi-server repair problem with switching failure and reboot delay and related profit analysis
TL;DR: This study examines a warm-standby machine repair problem which involves a switching failure probability, reboot delay and a repair pressure coefficient, and uses the probabilistic global search Lausanne method to determine the joint optimal parameter values that maximize the profit and satisfy the availability constraint.
Journal ArticleDOI
Original article: Standby system with general repair, reboot delay, switching failure and unreliable repair facility-A statistical standpoint
TL;DR: This study statistically examines an availability system with reboot delay, standby switching failures and an unreliable repair facility, which consists of two active components and one warm standby, using a consistent and asymptotically normal estimator of availability of such a repairable system.
