Journal Vol – 19 No -1, January 2024 Journal > Journal > Journal Vol – 19 No -1, January 2024 RELIABILITY OPTIMIZATION OF A DEGRADED SYSTEM UNDER PREVENTIVE MAINTENANCE USING GENETIC ALGORITHM Authors: Shakuntla Singla, Diksha Mangla, Poonam Panwar, S Z Taj DOI NO: https://doi.org/10.26782/jmcms.2024.01.00001 admin January 20, 2024 Abstract: The reliability parameters of a Mathematical model are analyzed for a system with three identical units and a standby. In this study, the primary unit is considered more important due to its high cost and working in two types of degraded conditions before a complete malfunction. Under the concept of preventive maintenance, the states of deterioration are reversed. The working of the system under two different efficiencies is discussed. The reliability of the Mathematical model, depending on the availability and working time, has been optimized using the Mathematical tool “Genetic Algorithm”. The optimum values of all parameters based on the exponential distribution are considered to optimize the reliability, and thus provide maximum benefits to the industry. Sensitivity analysis of the availability and the working time is carried out to understand the effects of changing parameters. Graphical and tabular analyses are presented to discuss the results and to draw conclusions about the system’s behavior.

Crossref, https://doi.org/10.14445/23488379/IJEEE-V10I4P104 Abstract: This paper reported the development of an alcohol sensor based on a glass substrate platform. The glass substrate was coated with two nanomaterial types: Hydroxyethylcellulose/Polyvinylidene fluoride (HEC/PVDF) and Agarose Gel, for comparison purposes. Three layers of coating material have been applied to the glass substrate to obtain the optimum sensing response. The coated glass substrate is kept dry for 24 hours before expose to variations of ethanol concentration to investigate the sensing response. A significant response to alcohol concentrations has been observed for both samples due to the changeable refractive index layer of the coating material. The sensitivity improved by a factor of 1.18 and 1.51, respectively, compared to the bared glass. The proposed sensor employed low-cost and commercially available components such as a glass substrate, LED light source and Arduino microcontroller to perform as an alcohol sensor. It prevents using expensive laser-based sensors, which is less practical in real industrial applications. Based on the experiment results, the HEC/PVDF-coated glass produced has demonstrated better results in terms of repeatability, hysteresis, stability and sensitivity as compared to agarose gel-coated glass. Hence the proposed sensor has a decent potential as an alcohol sensor Keywords: Alcohol sensor, Glass substrate, HEC/PVDF, Agarose gel. References: [1] G.
