Maintenance Optimization Model

A means of determining the optimal maintenance tasks  and maintenance intervals that minimize downtime while providing the most effective use of systems in order to secure the desired results at the lowest possible cost, taking all possible constraints into account. 


Objectives of the Model
The models can be either quantitative or procedure based: 

  • Minimizing: maintenance cost, down time, and time to repair. 
  • Maximizing: optimal performance, revenue, return on assets (ROA), return on investment (ROI) profit, time between failure, and reliability. 

Elements of the Model
Some of the tools, techniques, principles of a maintenance optimization model are listed below:

Some of the tools of maintenance optimization:
Comparing the Maintenance-Repair-Renewal (MRR) trade-offs at different organizations.
