Contextual dimensions for cache replacement schemes in information-centric networks: a systematic review [PDF]

PeerJ Computer Science, 2021
In recent years, information-centric networks (ICNs) have gained attention from the research and industry communities as an efficient and reliable content distribution network paradigm, especially to address content-centric and bandwidth-needed ...

Production Processes with Different Levels of Risk

Revstat Statistical Journal, 2021
It is often found that a company has the opportunity to change its original production process to a different one. Here we consider two different situations: in the first one, the new production process may lead to larger losses (in case the demand ...

Note on History of Age Replacement Policies [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2018
This paper tries to trace our research history briefly from Barlow and Proschan to attain general replacement models. We begin with a random age replacement policy that is planned at a random time Y and call it as random replacement.

A Summary of Replacement Policies with Number of Failures [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2018
Periodic replacement models with minimal repairs have been studied extensively. In order to prevent high repair costs after failures, this paper considers the number of failures as another decision variable for replacement policies.

An Imperfect Repair Model with Delayed Repair under Replacement and Repair Thresholds

Mathematics, 2022
Based on the extended geometric process, a repair replacement model of a degradation system is studied, in which the delayed repair time depends on the working time after the last repair. Replacement and repair thresholds describe when the system will be

What effect have commissioners’ policies for body mass index had on hip replacement surgery?: an interrupted time series analysis from the National Joint Registry for England

BMC Medicine, 2023
Background Despite their widespread use, the impact of commissioners’ policies for body mass index (BMI) for access to elective surgery is not clear. Policy use varies by locality, and there are concerns that these policies may worsen health inequalities.

Two Discrete-time Age-based Replacement Problems with/without Discounting [PDF]

International Journal of Mathematical, Engineering and Management Sciences
This paper considers two classical age-based replacement models within a discrete-time framework: a standard age replacement model and an opportunistic age replacement model.
