Inspecting Briquette Machine with Different Faults

Background: A briquette machine can be considered very useful in modern times as the need for energy consumption is increasing rapidly. Considering the harm to the environment, the study of the briquette machine is the need of present times. In this paper, the operative unit is considered as briquette machine, also known as bio-coal, which is used for agroforestry waste. Objective: A single operative unit has been analyzed stochastically. The inspection of the breakdown of a unit reveals the feasibility of the unit under the supervision of either ordinary or expert repairmen. Two types of faults are revealed by the repairmen, either minor or major. Minor faults are repaired immediately by the same repairmen, but whenever a major fault is held, the machine’s fault will be handled by an expert person. Method: It is assumed that the repair needs no modification once served. Availability, Mean-time for system failure, and profits are analyzed by utilizing the Regenerative point graphical technique and Semi-markov process. Results: The study reveals that the mean-time for system failure of the system model goes on decreasing as the failure rate increases and the availability goes on decreasing as failure-rate increases. Moreover, the study shows that the systems' profit goes down on an increase in Failure-rate. Conclusion: Findings of the study support the hypothesis that the limits of failure/repair/inspection rate will surely have effective profitability. Moreover, it is found that the utility of the scale of operation can easily be derived. The practical importance of biomass briquettes for burning coal or wood is very well appreciated. © 2022 Bentham Science Publishers.
