Saving and Accessing Reliability Results

Function and Action elements have three different types of results that can be saved and viewed:

• Those that are actual outputs of the element itself (and can be referenced by other elements);

• Internal outputs (of systems) and local properties that are exposed through the Reliability element’s Output Interface.

Function elements have five outputs that falls into the first category: the primary output of the element (which represents the component's status), the Failed output (which represents the status of the element’s failure modes), and three reliability and availability outputs. The Action element has an additional two outputs of this type: a count of the number of successful and unsuccessful actions.

You specify whether or not results for these outputs are saved by clicking the Final Values and/or Time History checkboxes at the bottom of the Definition tab for the element:

Like all element outputs, these outputs can be accessed by right-clicking on the output port of the element.

Note: The Final Values checkbox always controls whether Final Value results are saved. However, the Time History checkbox can be overridden. In particular, it is always applied for single realization runs, but is overridden for multiple realization runs. In particular, Time History results for multiple realization runs are only saved for outputs that are connected to Result elements.

Note: By default, the Failed output is not set to save time history results even for single realization runs (since it is an array). To save time history results for the Failed output, you must connect it to a Time History Result element or right-click on it in the output interface and select the Save Time History option.

In addition, GoldSim provides a number of reliability analysis results on the Results tab of Function and Action elements:

The "Summary" portion of the dialog automatically displays the key reliability metrics after a simulation is run.

The "Analysis Options" portion of the dialog provides three additional types of analyses (Causal Analysis, Failure Times and Repair Times). GoldSim will not carry out these analyses after a simulation is run unless the boxes are checked. By default, these are checked on. If a particular analysis has been saved, then after running the simulation the results can be viewed by returning to this tab and clicking on the Display button.

Note: The Display buttons are grayed out when the model is in Scenario Mode. That is, you cannot view these results when running and comparing scenarios.

The Participate in global export of reliability results checkbox allows you to indicate whether the element’s Summary statistics should be exported (to a spreadsheet) during a global reliability results export.

The “Output Interface Definition” portion of the dialog allows you to specify customized outputs associated with the element (e.g., if the element was system, this might by an output that exists inside the element).

Note: For any outputs created in the Output Interface Definition, whether or not results for these outputs are saved is determined by the Final Values and/or Time Histories checkboxes at the bottom of the Definition tab for the element:
