Sign Up to like & getrecommendations! Published in 2025 at "Applied Stochastic Models in Business and Industry"
DOI: 10.1002/asmb.2928
Abstract: The allocation of redundant components to a system is a common method for enhancing the system's lifetime. This study explores the optimal allocation of redundancies in series and parallel systems with two components by assuming… read more here.

DOI: 10.1007/s10479-020-03791-6
Abstract: In order to balance the deviation time between replacement and failure, a new notion of cost named as deviation cost is taken into account for planning replacement policies. We firstly take up a standard parallel… read more here.

DOI: 10.1080/01605682.2019.1614490
Abstract: Abstract Maintenance policies are developed for decision-making about repair and maintenance of deteriorating parallel systems consisting identical components whose failures are detected only by inspections. Inspections at periodic times reveal the true state of components… read more here.

DOI: 10.1080/03610926.2017.1300278
Abstract: ABSTRACT This paper studies the likelihood ratio ordering of parallel systems under multiple-outlier models. We introduce a partial order, the so-called θ-order, and show that the θ-order between the parameter vectors of the parallel systems… read more here.

DOI: 10.1080/03610926.2018.1429630
Abstract: ABSTRACT Consider two parallel systems with their independent components’ lifetimes following heterogeneous exponentiated generalized gamma distributions, where the heterogeneity is in both shape and scale parameters. We then obtain the usual stochastic (reversed hazard rate)… read more here.
