Background:
A briquette machine can be considered very useful in modern times as the need of energy
consumption is increasing rapidly. Considering the harm to environment, study of 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 breakdown of a unit reveals the
feasibility of the unit under the supervision of either ordinary or expert repairmen. Two types of fault are revealed by the
repairmen either minor or major fault. Minor faults are repaired immediately by the same repairmen but whenever major
fault held, the machine’s fault will be handled by 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.
Result:
Study reveals that the Mean-time for system failure of the system model go on decreasing as failure rate increase
and availability goes on decreasing as failure-rate increase. Moreover, the study shows that the systems profit goes down
on increase of Failure-rate.
Conclusion:
Findings of the study supports the hypothesis that the limits of failure/repair/inspection rate will surely have
effective profitability. Moreover, it is found that the utility of scale of operation can easily be derived. The practical
importance of biomass briquettes for burning coal or wood is very well appreciated.
