Dynamic segmentation

These segments are created dynamically, based on the rules that you specify when you initiate a need analysis run. If the asset groups that you select for the analysis include any linear assets, the Dynamic Segmentation Information page is displayed when you click Next on the Needs Analysis Information page. A linear asset can be segmented by length, by feature, or by condition.

To segment by length, specify the minimum and maximum length of each segment in the Min Length and Max Length fields.

To segment by feature, specify one or more features in the Rules by Feature grid. A new segment will be created wherever a point feature is located on the length of the asset, or where a range feature begins or ends. You can specify a general feature type, such as Attribute or Element, or you can use a specific feature within that feature type, such as a Surface Type attribute.

To segment by condition, specify one or more inspection indexes in the Rules by Condition grid. A new segment will be created whenever an index value changes. For each index you must also specify a tolerance formula. After segments are created based on the index values, the tolerance formula determines if adjacent segments should be combined for the analysis. For example, a tolerance formula might combine segments if the difference in the value of the inspection index is less than one.

You can also combine segmentation methods. For example, if you specify a maximum length as well as entering features in the Rules by Feature grid, Infor Public Sector will first create segments by feature. The resulting segments are then compared to the maximum length that you specified, and any segments that exceed this length are further divided.

If you combine feature-based segmentation and condition-based segmentation, the feature-based rules are applied first, and assets are then further segmented by condition.
