AVAILABILITY IMPROVEMENT OF A SYSTEM USING SUBSTITUTE SYSTEM
Keywords:
Abstract
In present paper repair and replacement policy of one unit system is considered with substitute system.Assuming failure and repair times as exponentially distributed, expressions for the mean time to system failure (MTSF) and the steady state availability for system are derived using linear first order differential equations. A particular case for the proposed system is discussed in which substitute system is not considered. Graphical comparison is also performed to observe the effect of the proposed system on Availability.
p>In view of the above, the search for alternative fuels is an ongoing research field. The combustion of fossil based fuels (natural gas, oil, gasoline, petroleum diesel fuel etc.) is a one way process which will eventually exhaust the available stocks of raw petroleum materials and will add significant amount of carbon-dioxide in the atmosphere. A good alternative fuel would ideally come from renewable resources, energy-rich, “green” in its production and be at least “carbon-neutral”.
Biodiesel Fuel (BDF) is one such alternative, which meets the needs of a safer and cleaner alternative to the commercial petroleum diesel. The synthesis of biodiesel is not that simple, which is why we don’t find its synthesis on a large industrial scale in any country.
In this review the synthesis, properties, applications, scaling-up issues and solutions of BDF are addressed in length and breadth. The review is based on the selected accounts of the up to date research carried in the field of biodiesel. The selected accounts have the potential for a smarter process of a smarter fuel for a smarter and safer environment.
