Sensor Set Analysis

When some operations are performed on a sensor set, the coverage, diagnostic

sets and ambiguity groups are subject to changes by the user i.e. current

characteristics of a sensor set need to be regenerated to view display the

changes.

When a sensor set is out of sync, a warning icon will appear on the sensor set

icon, all calculation results will be italics and the reanalyse options will be

available. To reanalyse a sensor select the "Analyze" button from the

Analysis Parameters section on the Sensor Set Analysis Options page.

Performing a Sensor Set Analysis:

1. Select "Diagnostics Analyses" under "Analyses" in the Main Menu.
2. Create a new or open an existing Diagnostics Analysis.
3. Select "Sensor Set Analysis" in the options on the left.
4. Adjust the Analysis Parameters in the "Analysis Parameters" section on the left.
5. Click on the "Analyze" button to begin sensor set analysis.

Coverage

This section displays a list of options that the user can set to limit aspects

of the diagnostic analysis. The main parameters to set include coverage, limits for

number of test points and sensor sets and the number of iterations required when

generating sensor sets using built-in algorithms. To specify or limit the coverage

required for a sensor set analysis:

1. Select the check-box to limit coverage.
2. Enter target coverage using the number field or use the spinner to increase/decrease values.

Test Points

The next option limits the number of test points required for each diagnostic

analysis sensor set. To specify or limit the number of test points required for

a sensor set analysis:

1. Select the check-box to limit test points.
2. Enter a value to specify the number of test points required using the number field or use the spinner to increase/decrease values.
3. Enter a value to specify the distribution range (limited to 1-10) e.g. specifying 7 test points with a range +/- of 1 will prioritise sensor set results with a range of 6-8 sensed test points.

Analysis Options

The next sensor set options are analysis options which specify the number of

sets that are generated. The depth of analysis selected will influence the

analysis time due to the number of iterations before the genetic algorithm

terminates. Higher number of iterations may produce better sensor sets with better

fitness. To specify the number of sets and analysis depth:

1. Enter a value to specify the number of sets required using the drop-down menu (choose between 10, 25, 50 or 100).
2. Select the drop-down menu to select the depth of analysis: Low (1,000 iterations), Moderate (10,000 iterations), or High (100,000 iterations).
