Outputs
After the input data is analyzed, Prescriptive Maintenance on Cloud provides the maintenance margin, top drivers, and risk factors.
Maintenance margin
Maintenance margin is a calculation that represents the number of days between the next scheduled maintenance and the expected failure date. Use this information to adjust maintenance schedules. A negative number implies that equipment will fail before the next scheduled maintenance, so the schedule should be advanced to avoid failure. A positive number implies that equipment will fail after the next scheduled maintenance so scheduled maintenance can be postponed.Top drivers
Top drivers is a sensitivity analysis that shows the strength of correlation between operating variables and failure for each equipment instance. Prescriptive Maintenance on Cloud ranks the drivers, indicates the current value of each driver, and provides an estimate of the remaining value before failure in the driver unit. For example, the top failure for a pump might be the cubic feet of water pumped since last repair. At the time of analysis, pump 2672 has pumped 40000 cubic feet of water. Prescriptive Maintenance on Cloud estimates that it pump another 10000 cubic feet before it fails. This value is intended as an estimate. When this estimate is produced, Prescriptive Maintenance on Cloud assumes that the values of the other drivers remain constant. The actual number of operating hours is influenced by the changes in other variables.Risk factors
Risk factors are characteristics of equipment that make them more or less susceptible to failure. Unlike drivers, which are continuous numeric variables, risk factors are categorical characteristics of the equipment. They are useful in explaining why different equipment instances that are used in a similar way have different failure rates. For example, pump 2672 has pumped 40000 cubic feet of water since the last repair, and can pump 10000 more cubic feet before failure. However, pump 8251 has also pumped 40000 cubic feet of water, but it can pump only 10 more cubic feet. Pump 2672 is used in a clean environment. Pump 8251 is used in a corrosive environment. The environment is shown as a risk factor with a clean environment shown as a positive contributor for pump 2672 and a corrosive environment is shown as a negative contributor for pump 8251.
