Profit Analysis of Non-Identical Parallel System with Two Types of Failure Using Discrete Distribution

This paper has analyzed the two non-identical operative parallel systems considering two units (automatic and manual one) by using regenerative point technique. For theautomatic unit, the concept of inspection policy has been introduced to detect the kind of failures (major or minor) before being repaired by some repair mechanism. Butthe manual unit is free from such inspection policy. Various important measures of reliability i.e MTSF, steady-state availability, a busy period of repairman and inspector,profit function has been evaluated by designing a model for the system and using discrete distribution & regenerative point techniques. Profit function and MTSF are also analyzed graphically

Probability Analysis of a Complex System Working in a Sugar Mill with Repair Equipment Failure and Correlated Life Time

The aim of this paper is to present a reliability analysis of a complex (SJP) system in a sugar mill with the assumption that repair equipment may also fail during the repair. This paper considers the analysis of a three-unit system with one big unit and two small identical units of a SJP System in a sugar mill. Failure and Repair times of each unit are assumed to be correlated. Using regenerative point technique various reliability characteristics are obtained which are useful to system designers and industrial managers. Graphical behaviors of MTSF and profit function have also been studied

Computational Study Reliability of Diesel Engine through Electrical Assembly

Consistency of a system is the probability that, under defined operational and environmental conditions, the device can perform a specific function at the end over a specified time [Dinkar et al. 2018]. Reliability must be defined by definitive norm based on many variables, maximum of that may random [Bhardwaj et al. (2018)]. Reliability is arduous to scale, because no such tool is there to do this for specific machine. The reliability of the diverse units of complex machinery depends on their output process, the standard of the composites used in their design, operating conditions, etc. Despite these criteria the reliability of the system is very much related to diverse forms of uncertainty. The numerical assessment of ambiguities is therefore the starting point for a numerical assessment of reliability [Bhardwaj et al. (2019)]. The theory of probability is a concept concerned with the analysis of risk [Li, Y. - F et al. 2006]. Maintenance regulations can address issues pertaining to general maintenance, fix or dump laws, rules on emergency reporting, inventory control, supply of spare parts, etc. Such maintenance policies may be defined in advance and implementation decisions may be taken accordingly. The design process involves unit length assessments, research protocols, degree of automation as well as integrated redundancies, test time, specific test facilities and measures for safety; and so forth [Allan, T.M., 2012]. Performance is an attribute of reliability to reparable systems which accounts for the quality and service property of a component or device. ABC appraisal seeks to distinguish the item from each other and decide the importance of the element and the degree as required by company

Assessment of Phytoremediation Potential of Chara vulgaris to Treat Toxic Pollutants of Textile Effluent

Textile effluent released into water bodies is prone to be toxic for aquatic flora and fauna. In the present study, the phytoremediation potential of Chara vulgaris (C. vulgaris) is investigated for treatment of textile effluent. The highly concentrated and toxic textile effluent is diluted to different concentrations 10%, 25%, 50%, and 75% to check the accessibility of macroalgae to bear pollutant load of textile effluent. The toxicity of textile effluent is analysed by determining different water quality parameters, namely, pH, TDS, BOD, COD, and EC. The maximum reductions in TDS (68%), COD (78%), BOD (82%), and EC (86%) were found in the 10% concentrated textile effluent after 120 h of treatment. The highly concentrated textile effluent showed its toxic effect on macroalgae and it was found unable to show a remarkable change in water quality parameters of 75% and 100% textile effluent. The correlation coefficient values are determined using correlation matrix to identify the high correlation between different water quality parameters. The removal of toxic organic pollutants by C. vulgaris was confirmed by using UV-visible absorption spectra. Typical X-ray spectra recorded using EDXRF technique indicated the presence of heavy metals Cd in the dried sample of macroalgae after treatment which show its capability to remove toxic heavy metals from textile effluent. The reliability model has been proposed for treated textile effluents to identify percentage level of toxicity tolerance of waste water by macroalgae

Reliability analysis of two unit parallel repairable industrial system

The aim of this work is to present a reliability and profit analysis of a two-dissimilar parallel unit system under the assumption that operative unit cannot fail after post repair inspection and replacement and there is only one repair facility. Failure and repair times of each unit are assumed to be uncorrelated. Using regenerative point technique various reliability characteristics are obtained which are useful to system designers and industrial managers. Graphical behaviors of mean time to system failure (MTSF) and profit function have also been studied. In this paper, some important measures of reliability characteristics of a two non-identical unit standby system model with repair, inspection and post repair are obtained using regenerative point technique
