Reliability Testing of Wind Farm Devices Based on the Mean Time to Failures
Energies, 2023 Nowadays, one of the main sources of renewable energy is wind energy; therefore, a wind farm’s electricity system must be effective. As a result, wind farm (WF) equipment must continuously operate without failure or damage.

Accelerating mean time to failure computations [PDF]
Performance Evaluation, 1996 Summary: We consider the problem of numerical computation of the mean time to failure (MTTF) in Markovian dependability and/or performance models. The problem can be cast as a system of linear equations which is solved using an iterative method preserving sparsity of the Markov chain matrix. For highly dependable systems, system failure is a rare event

Challenging the Mean Time to Failure: Measuring Dependability as a Mean Failure Cost
2009 42nd Hawaii International Conference on System Sciences, 2009 As a measure of system reliability, the mean time to failure falls short on many fronts: it ignores the variance in stakes among stakeholders; it fails to recognize the structure of complex specifications as the aggregate of overlapping requirements; it fails to recognize that different components of the specification carry different stakes, even for ...

Mean Time to Failure and Availability of Semi-Markov Missions With Maximal Repair
European Journal of Operational Research, 2010 We analyze mean time to failure and availability of semi-Markov missions that consist of phases with random sequence and durations. It is assumed that the system is a complex one with nonidentical components whose failure properties depend on the mission

Mathematical model for analysing availability of threshing combine machine under reduced capacity [PDF]
Yugoslav Journal of Operations Research, 2022 Obtaining system availability in an engineering design is trickish and challenging, especially when there is a reduction in capacity; however, it supports system maintainability.

Total productive maintenance policy to increase effectiveness and maintenance performance using overall equipment effectiveness [PDF]
Journal of Applied Research on Industrial Engineering, 2019 In the manufacturing process, the machine is very important because downtime can inhibit and even stop production. We focused on the highest downtime that occurred in a particular product line and critical machine. This research contributes to overcoming
