The Setup Defects window defines the defects used by your agency and how a defect score is calculated. Defect scores are important for maintenance analysis.

This window provides the following columns:

• Asset Type: This column shows the asset type to which the feature belongs.
• Best Value: This column stores the defect value that indicates perfect condition.
• Expression for Inv. Totals: This column provides the SQL script that determines how the total amount of the asset for the defect is calculated.
• Feature: This column lists the defect elements.
• Groovy Script ID: This column contains a drop-down list of Groovy scripts. You select the appropriate Groovy script to determine the "Scenario Cost" that will achieve a "Desired LOS," where the "Current Cost" and the "Current LOS" are known.
• MMS Util Function: The MMS Utility function is the defect score/grade-related function that is used for optimization in maintenance analysis. For example, if you want to optimize directly on defect score, then the utility function is simply the defect score. If you want to give 20% extra priority to interstates, then the utility function would multiply defect scores by 1.2 for interstates. This column contains a drop-down list of Groovy scripts. You select the appropriate Groovy script that defines and sets the utility function.
• SQL for Defect Summary: This column provides the SQL script that determines the defect score for the feature.
• Worst Value: This column stores the defect value that indicates the lowest possible condition.
