Exporting Results


All layouts generated in the optimization controller are saved to the Risk Data Set in which the optimization was run on. If the Risk Data Set is deleted, then so will the optimization data.


There are three export options from the optimization controller:

  • Export Layout - exports an excel of the detector coordinates, a Detect3D (.d3d) file, or DWG CAD file of the optimized layout

  • View and export the Detection Matrix - a table of every case simulated and indication for which detectors went into alarm for the selected layout

  • Export Coverage Data - exports an excel file showing the order of devices used, coverage data points and graph of the coverage achieved


Export the layout and associated coverage for Gas Detector Layout 04:

  1. Open the optimization controller and right-click Gas Detector Layout 04

  2. Select the Export Layout ( Picture 24 ) option first, in the window that appears ensure that the Save as type is set to Excel Document (*.xlsx) and name the file

  3. Right-click Gas Detector Layout 04 and export the Coverage Data ( Picture 26 )



Open the excel file generated from the Export Layout option. The tabs for the exported layout are shown below containing a cover page, a layout summary page and a listing of each of the point and open path devices with their coordinates in CSV format.

Open the Coverage Data excel file. This file provides the list of the devices used to achieve the coverage target in order or priority. The list also shows the contribution to 1ooN and 2ooN coverages along with the corresponding graph.

Detect3D files may also be exported in Step 2 above, when setting the save directory choose .d3d as the file format, shown below. This allows for comparison of geographic gas mapping method with scenario, frequency and risk-based gas mapping methods.

Lastly, open the Detection Matrix window(Picture 25). The window is populated with rows representing each case run and columns for each detector in the selected layout, as shown below. A symbol will be present in the cells to indicate which detector had an alarm and/or control trigger for the listed simulations. The o symbol is used for Alarm and the ⨂ symbol for control.


At the top of the window you can opt to have only a selection of the rows to be listed, as seen in the figure below. Available options are:

  • Show All Scenarios - will have rows for every simulation run in the table

  • Show Detected Only - only cases that were detected will appear in the table

  • Show Undetected Only - only cases NOT detected will appear in the table

  • Contribution Detection Only (Alarm) - showing cases which had an alarm trigger from detectors contributing to the coverage in the selected layout

  • Contribution Detection Only (Control) - showing cases which had a control trigger from detectors contributing to the coverage in the selected layout

  • Contribution Detection Only (Both) - showing cases which had both an alarm and a control trigger from detectors contributing to the coverage in the selected layout


Using the Export button in the upper-right corner of the window will export the current view of the Detection Matrix Window to Excel.
