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...

Dimensions and Constituents of a Desired Model for Setting Guidelines within the Iranian System of Education

The educational system of any country plays a significant role in its sustainable development and progress. However, to fulfill this function there must exist a set of guidelines and policies aimed at such development. The process of setting such a set of guidelines requires a homegrown model for development of the guidelines, and their implementation and supervision. To this end, 14 interviews...

Does the Narrative About the Use of Evidence in Priority Setting Vary Across Health Programs Within the Health Sector: A Case Study of 6 Programs in a Low-Income National Healthcare System

Background There is a growing body of literature on evidence-informed priority setting. However, the literature on the use of evidence when setting healthcare priorities in low-income countries (LICs), tends to treat the healthcare system (HCS) as a single unit, despite the existence of multiple programs within the HCS, some of whic...

A Multi-Stage Single-Machine Replacement Strategy Using Stochastic Dynamic Programming

In this paper, the single machine replacement problem is being modeled into the frameworks of stochastic dynamic programming and control threshold policy, where some properties of the optimal values of the control thresholds are derived. Using these properties and by minimizing a cost function, the optimal values of two control thresholds for the time between productions of two successive nonco...
