Calibration

Add calibration data and parameter weights for screening. Default values are autofilled, which were agreed upon by sector subject matter experts in reference to assets nationwide. To change any of these figures, simply uncheck the option and enter your calibration data. Deleting an entry will repopulate the autofilled default value.

I would like to use default values for:

Screening Criteria

For each consequence parameter you can use the default values or elect to set customized values.

Definitions for screening criteria data are as follows:

  • Criticality: The value at which any additional increase in loss would be critically detrimental. This is the level which you want to screen against.
  • Maximum: The upper threshold or largest amount of potential impact and/or loss due to a breach or failure of a facility under a worst reasonable case scenario.
    • The eight ranges provided for each parameter are assigned based on the maximum limit. If you change this maximum, there will be an associated change in the ranges of the Facility Data.

Human Impacts

Impacts on human health and safety caused by inundation of downstream populated areas, industrial areas, and other critical infrastructure assets.

Economic Impacts

Impacts associated with damages to the facility, direct damage to downstream inundated areas, and direct monetary impacts associated wit lost project benefits.

Impact on Critical Functions

Impacts associated with damages to the facility, direct damage to downstream inundated areas, and direct monetary impacts associated wit lost project benefits.

Relative Weights Selection

For each prioritization category and question you can use the default values provided or elect to set customized values.

Definitions for relative weights selection data are as follows:

  • Parameter Weight: The relative importance of each individual parameter. Provide weights for each category and parameter between 0-100, with 100 being of highest importance. There are no restrictions on weighting. Numbers can be used more than once, and do not need to sum to any particular total. All weights are normalized during the prioritization process.

Severity Index Function Options

For each severity index function option you can use the default functions or elect to set customized functions.

Definitions for severity index function options are as follows:

  • Model Type: The combination of functions utilized to obtain prioritization output.
    • Discrete vs. Continuous: If estimated values for all 14 parameters are not known, using the discrete function is recommended. If estimated values for all 14 parameters are available, using the continuous function is recommended. This allows for a more refined outcome.
    • Linear vs. non-linear: These options differ in how higher severity levels are scaled. In the linear case, each unit change in severity level of a consequence parameter leads to a fixed change in the resulting index, whereas the non-linear case will change exponentially.
