Event Codes

The Multiple Systems with Event Codes data type analyzed with the Crow Extended model uses a column to indicate the types of events that occurred during a test phase. Within RGA, event codes are entered within the Event column of the Multiple Systems with Event Codes data sheets.

The possible event codes that can be used in the analysis are:

I: denotes that a certain BC failure mode has been corrected at the specific time; in other words, a fix has been implemented. For this data type, each BC mode must have an associated I event. The I event is essentially a timestamp for when the fix was implemented during the test.
Q: indicates that the failure was due to a quality issue. An example of this might be a failure caused by a bolt not being tightened down properly. You have the option to decide whether or not to include quality issues in the analysis. This option can be specified by checking or clearing the Include Q Events checkbox under Event Code Options on the Analysis tab.
P: indicates that the failure was due to a performance issue. You can determine whether or not to include performance issues in the analysis. This option can be specified by checking or clearing the Include P Events checkbox under Event Code Options on the Analysis tab.
X: indicates that you wish to exclude the data point from the analysis. An "X" can be placed in front of any existing event code (e.g. XF to exclude a particular failure time) or entered by itself. This row of data will then not be included in the analysis.
S: indicates the system start time. This event code is only selectable in the Normal View.
F: indicates a failure time.
E: indicates the system end time. This event code is only selectable in the Normal View.
The analysis is based on the equivalent system that combines the operating hours of all the systems.
