A note on the optimal replacement policy

Optimal overhaul–replacement policy for a multi-degraded repairable system sold with warranty

In this research, we study an optimal overhaul–replacement policy of a multi-degraded repairable system sold with a free replacement warranty. In the proposed replacement policy, a maintenance action and failure are dependent on a system degradation level and the system age, and hence the replacement model will provide more effective maintenance decisions. Failure of the system is modeled using...

The optimal age-based replacement policy for systems subject to shocks

In this article, two different systems subject to shocks occurring based on a non-homogeneous Poisson process (NHPP) are analyzed. Type –I system is consisted of a single unit and type –II system is consisted of two parallel units in which both units operate identically and simultaneously. In type –I system occurrence of a shock causes system stopping and consequently will be received minimal r...

A Note on the Criteria of Optimal Solution for Replenishment Policy for Ameliorating Item with Shortages

Ameliorating products are frequently seen in stock management. Considering ramp type pattern of time dependent demand for such products is a justification for the development of related inventory theory. In a recently published paper by Singh et al. (2011), such kind of problem is discussed. However, the solution given by author is incomplete because that fails to depict the case for optimal re...
