All three machines are available for production a higher percentage of time when scheduled maintenance is in effect. The highest availability level is significantly higher than the availability level when there is no scheduled maintenance for both Machines 2 and 3. Likewise, the ROC figures show the same results. In this simulation the ROC is a result of changes in both revenue and direct costs. Although the level of the ROC is not necessarily indicative of what a company can achieve by properly managing maintenance, the fact remains that maintenance does have a significant impact on ROC in some cases. These results illustrate that a company may be hurting itself competitively if the maintenance function is not incorporated as part of its business strategy.
