Uncertainty and Sensitivity Analysis - Analysis Type

Analysis Type

Data on the Analysis Type tab allows you to define the analysis and its level of complexity.

Analysis

The following options are available:

1-Parametric analysis - to run a parametric analysis with up to 2 design variables and any number of Output KPIs on the Y-axis. See the specific section on Optimisation and Parametric analysis for more details on this option.
2-Optimisation - to run an optimisation with 1 or 2 design objectives and any number of design variables, constraints and additional outputs. See the specific section on Optimisation and Parametric analysis for more details on this option.
3-Uncertainty/Sensitivity analysis - to run an uncertainty and sensitivity analysis (UA/SA) with any number of outputs and design variables.

Note: Optimisation and UA/SA results and simulation tools are accessed from the Optimisation + UA/SA tab on the Simulation screen, while Parametric analysis results and simulation tools are accessed from the Parametric tab.

Level

The Level setting is only available for Uncertainty and Sensitivity Analysis and can be used to set the level of complexity of the problem definition using one of 1-Simple or 2-Detailed. The option selected may depend on the problem at hand and on your level of experience with statistical methods.

1-Simple

The 1-Simple level option provides access to only the most frequently used variable distributions when defining the Design Variables.

12-Log-Normal
14-Normal
18-Triangular
19-Uniform

2-Detailed

The 2-Detailed level option provides access to an exhaustive list of variable distributions when defining the Design Variables.

* Only available for List Type Variables

Note: The additional distribution curves available with the detailed option require advanced statistical understanding to manage the curves. The Detailed option should therefore be used by advanced users only.
