Use the Maintenance Analysis window to set up and run analysis scenarios. Running these scenarios:

• Estimates the budget needed to obtain a user-defined Maintenance Index value; or
• Allocates a user-defined budget to maximize a Maintenance Index value using incremental cost-benefit analysis.

Two methods of analysis can be used:

• By Budget: Defines the optimum mix of work based on a target budget.
• By Index: Defines the optimum mix of work to achieve a performance target.

Multiple scenarios can be run, with their inputs and results saved by scenario for future reference. For a model to be calculated from the information displayed in this window:

• The activity must be defined in the system, must have a Performance Guideline associated with it, and must have a defect assigned to it (at a positive percentage) in the Setup Defect Activities window.
• The asset type must be defined in the system and associated with a defect.
• A work order summary amount for your administrative unit, current year, activity, and class code must exist, and both the amount and cost must be positive.
• An inventory total for your administrative unit, current year, asset type, and class code must exist, and the amount must be positive.
• A defect survey summary for your administrative unit, current year, defect, and class code must exist, and the failed percentage must be between 0 and 95%.

If any of this information is not available, then the defect and its resolution will be excluded from the analysis.
