Assigning uncertainties in the simulation study

On the Assign Uncertainties form of the Simulation Study workflow (jewellabs > Simulation Study > Assign Uncertainties) you select the parameters that you want to incorporate as 'uncertain' in your dynamic simulation. Only those parameters that are set to 'uncertain' in the corresponding workflow steps will appear for selection on the form.

Each uncertainty parameter that you select on the form will be sampled by CMOST per realization.

After exporting the study, if you make any changes to your uncertainty parameters, for example updating their PDFs (probability density functions) or selecting or deselecting them on the Assign Uncertainties form, you must reexport the study.

To assign uncertainties

  1. On the Assign Uncertainties form, under Simulation Study, select the relevant simulation study from the drop-down list.
  2. The table on the form is auto-populated with all the parameters in the domain models of your concept can be propagated as 'uncertain' to the dynamic simulation and are set as 'uncertain' with the Uncertainty Parameter dialog . Select the parameters that you want to incorporate as 'uncertain' in your simulation; parameters for which the box is not checked will not be considered 'uncertain' and their Reference Value will be used during the simulation. The Reference Value is the value on the domain model form, and is also displayed at the base of the Uncertainty Parameter dialog.
    3. The table lists all uncertainty parameters that can be propagated to dynamic simulation and are specified as 'uncertain' on the corresponding form in the workflow. The list contains the model name, model type, unit, reference value, dependency, together with a section with basic statistics of the Probability Density Function (when the uncertainty parameter is a seed, this section is empty). Default uncertainty parameter names (in the Parameter column) can be long, as they are built up as follows: 'prefix (i.e. abbreviation of the model type) - parameter type- user defined part - suffix (I.e. associated model name)'. To expand the column to display the full name, right-mouse click on the column header and select Best Fit or Best Fit (all columns). Alternatively, you can shorten the user defined part of the name on the Uncertainty Parameter dialog.
  3. Click Apply to assign the uncertainty parameter(s) to the simulation and keep the form open, or click OK to assign the uncertainties and proceed to the Export Study step.
