Availability and reliability of a manufacturing system are the most common indicators in the reliability engineering area to assess the quality and on-time deliveries of the products they produce. The purpose of this paper is to analyze the availability, reliability. failure metrics such as MTBF and MTTF, and also steady-state availability of a cooking oilproduction line using a Markov approach. The product line works in three consecutive shifts 24 hours a day, for which five main subsystems are identified for the analysis. The results show that the first shift has the best performance in terms of reliability while the second shift has the worst performance. To improve the reliability of the production line, a corrective maintenance policy is used. First, the critical components of the subsystems are identified using the Pareto charts, and then, by increasing the repair rates, the availability of the production line in all three shifts is increased.

Graphical Abstract

Availability analysis of a cooking oil production line


  • The availability and reliability of a cooking oil production line is analyzed using the Markov approach
  • Five main subsystems are identified for the analysis
  • A corrective maintenance policy is assumed
  • The critical components of the subsystems are identified using the Pareto charts
  • By increasing the repair rates, the availability of the production line is increased
