Analysis and Scheduling of Maintenance Operations for a Chain of Gas Stations
Table 5
Various parameters and maintenance cost comparisons for 3 categories of dispensers.
| | Category | Number of
failures/year | Number of
PM/station/year | Number of stations | CMC | PMC | TMC | Percent reduction in cost |
| | High failure stations—under current PM | 3281 | 3 | 7 | 40161 | 1498 | 41695 | | | High failure stations—under proposed PM | 2747 | 6 | 7 | 33696 | 2992 | 36688 | 14% | | Medium failure stations—under current PM | 2101 | 3 | 15 | 25718 | 900 | 26688 | | | Medium failure stations—under proposed PM | 1395 | 4 | 15 | 17075 | 1199 | 18274 | 31% | | Low failure stations | Current and proposed PM schedules are the same and thus the costs are not affected |
