Summary Supplement to Chapter Fourteen Maintenance Maintaining the productive capability of an organization is an important function. Maintenance includes all activities related to keeping facilities and equipment in good operating order and maintaining the appearance of buildings and grounds. The goal of maintenance is to minimize the total cost of keeping the facilities and equipment in good working order. Maintenance decisions typically reflect a trade-off between preventive maintenance, which seeks to reduce breakdowns and failures, and breakdown maintenance, which seeks to reduce the impact of breakdowns when they occur.

Key terms include breakdown maintenance, maintenance, predictive maintenance, total productive maintenance, and preventive maintenance.

Discussion and Review Questions

  1. What is the goal of a maintenance program?
  2. List the costs associated with equipment breakdown.
  3. What are three different ways preventive maintenance is scheduled?
  4. Explain the term predictive maintenance and the importance of good records.
  5. List the major approaches organizations use to deal with breakdowns.
  6. Explain how the Pareto phenomenon applies to:
    • a. Preventive maintenance
    • b. Breakdown maintenance
  7. Discuss the key points of this supplement as they relate to maintenance of an automobile.
  8. What advantages does preventive maintenance have over breakdown maintenance?
  9. Explain why having a good preventive maintenance program in place is necessary prior to implementing a lean system.
  10. Discuss the relationship between preventive maintenance and quality.

Consider a scenario in a hospital laboratory where the probability of equipment recalibration needs varies monthly. A service contract costing $650 per month covers all necessary recalibrations, which cost $500 each when performed individually. Comparing costs, it becomes evident whether the service contract or on-demand recalibration is more economical based on the probability of recalibration needs.

Similarly, for a lottery ticket issuing machine with a certain breakdown frequency, and repair costs averaging $240, the choice between paying for preventive maintenance versus paying per repair depends on expected costs calculated via probability and statistics.

In equipment maintenance scheduling, the optimal preventive maintenance frequency is normally distributed, accounting for the average time between breakdowns and variability. Cost-effectiveness depends on balancing maintenance costs against breakdown risks, which helps maintain efficiency and minimize downtimes in manufacturing or service environments.

Applying Maintenance Principles to Automotive Care

Proper maintenance of an automobile involves understanding the trade-offs between preventive and breakdown maintenance. Regular oil changes, tire rotations, and inspections exemplify preventive strategies that can prevent costly repairs or breakdowns. Conversely, waiting until a part fails to repair it—breakdown maintenance—can result in higher costs and inconvenience. Implementing a preventive maintenance schedule often extends vehicle lifespan, improves safety, and enhances performance, aligning with the principles outlined in this supplement.

Conclusion

Effective maintenance management balances costs, reliability, and safety, ultimately ensuring continued operational efficiency. Adopting preventive maintenance strategies and understanding their relation to quality and cost can lead to significant savings and improved organizational performance.
