Ring Placement Criteria in 5.1 and Later

To create rings based on selected location options:

1.     After selecting Ring Accumulation as the analysis type, select Step 2 - Configure.

2.     On the Accumulate tab, in the Ring placement criteria area, choose one of the following four options:

a.     Select Dynamic Ring if you want the system to determine the optimal location for placing a ring of a given size.

This option generates ring locations based on exposure locations so that you can identify the highest concentrations.

b.     Select Top <n> risks by total replacement value if you want to run the analysis based on high-value locations in your portfolio, and then enter the number of risks.

For property exposures, the default of 1,000 represents the top 1,000 risks by total replacement value. For workers' compensation analyses, the default represents risks by the total number of employees.

c.    Select AIR Landmarks and then select one or more landmarks to put rings on high-trophy targets.

You can select one or more categories. ExampleYou might want to evaluate potential losses for a terrorist attack on airports and bridges near your exposures. To use this feature, model M01, the AIR Terrorism Model for the U.S., must be licensed.

d.    Select Address List to use specific addresses around which to create rings. Click the Pencil icon to open the Address List Editor.

•       To add addresses manually, click , enter address information, and then click OK.

The Ring Center Name, Latitude, and Longitude fields are required.

•       To copy and paste records from a spreadsheet into the Address List, open a spreadsheet containing the addresses, right-click the row or rows containing the addresses you want to copy, and click Copy on the shortcut menu. In the Address List Editor click Paste and then click OK to save the changes.

The system displays information about the number of locations that you loaded.

3.     Select the Remove duplicates check box if you do not want the system to place duplicate rings—rings of the same radius—around the same latitude and longitude—for overlapping exposures, that is, exposures that are at the same XY locations.

This option does not apply to a Dynamic Ring analysis.
