Navy has made a huge applying of preventive maintenance that has been recognized as the greatest source of costs. Scheduled overhaul is the most expensive. Revising preventive maintenance and selecting maintenance concepts according to a new algorithm should result into lowering those costs and at the same time maintaining function safety and system readiness. A reversible FMEA analysis coupled...

Every industry is dependent on some type of asset that keeps the business in business be it a computer, a CNC, or a megawatt transformer. In a large enterprise, reducing costs related to asset maintenance, repair, and ultimate replacement is at the top of management concerns. Downtime in manufacturing ultimately results not only in high repair costs, but in customer dissatisfaction and lower po...

In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied.  The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...

Purpose: To compare, in commercially-insured individuals ≥40 years old, the risk of chronic obstructive pulmonary disease (COPD) exacerbations and COPD-related health care utilization and costs in patients initiating maintenance treatment with fluticasone propionate/salmeterol xinafoate 250 μg/50 μg (FSC) with those in patients initiating treatment with tiotropium bromide (TIO) Design: Retrospe...
