Once you have calculated the parameters for the Multiple Systems with Event Codes data type or any multi-phase data type, you can choose Growth Data > Analysis > Event Report to view a special report in the Results window. The Event Report can consist of up to five tabs, depending on the types of events defined in the data set. The tabs are described next.
The Mode Summary tab is always displayed and it provides the following information for each unique failure mode in the data sheet:
Mode and Classification: The unique identifier and classification (A, BC or BD) for the failure mode.
First Failure: The time of the first failure due to that mode.
Total Failures: The total number of failures due to that mode.
For the Multiple Systems with Event Codes data type, there is one additional column.
Effectiveness Factor: The effectiveness factor assigned for each BD failure mode.
For multi-phase data types, there are three additional columns. These columns are applicable only for BD failure modes that do not have an implemented fix time (I event) in the data set. For these failure modes, the Effectiveness Factors window records the phase after which the fix will be applied, if any, along with the estimated effectiveness factor. Therefore, the report displays:
Nominal EF: The effectiveness factor that will be used for "nominal" calculations (e.g., nominal projected MTBF, etc.). These calculations represent the best case scenario in which a fix is applied to every BD failure mode, even if the fix is marked "Not Implemented."
Phase Fixed: A number indicates the phase after which the fix was applied (e.g., the number 2 indicates that the fix was applied after the end of Phase 2 but before the start of Phase 3). "Not Implemented" indicates that the fix has not been applied.
Actual EF: The effectiveness factor that will be used for "actual" calculations (e.g., actual projected MTBF, etc.). These calculations take into account which delayed fixes have actually been implemented in the current management strategy. Therefore, if the fix is "Not Implemented," the actual EF will be zero.
The Implemented Fixes tab is present only if the Multiple Systems with Event Codes data set contains BC failure modes, or if the multi-phase data set contains BD failure modes that have an implemented fix time (I event) in the data set. For each applicable failure mode, this tab provides the following information:
Mode and Classification: The unique identifier and classification (A, BC or BD) for the failure mode.
First Failure: The time of the first failure due to that mode.
Total Failures: The total number of failures due to that mode.
Before Fix Failures and After Fix Failures: The number of failures due to the mode that occurred before and after the fix was implemented.
Before Fix Runtime and After Fix Runtime: The amount of operating time before and after the fix was implemented. In a Multiple Systems with Event Codes data sheet, this is the sum of the operating times for all affected systems.
For the Multiple Systems with Event Codes data type, there is one additional column:
Systems With Fixes: The number of systems for which the fix was implemented.
For multi-phase data types, if the Allow EF values for BD modes with implemented fixes option is selected on the on the Calculations page of the Application Setup, there are two additional columns:
Effectiveness Factor and Comments display any additional information that you have entered on the Implemented Fixes tab in the Effectiveness Factors window. This information is for your information only and is not considered in the data analysis.
The Quality Events tab and the Performance Events tabs are present only if the data set contains events of these types. These tabs provide summaries for the events that have been marked with the Q and P event types.
The Mode Fix List tab is present only if fixes have been implemented to Multiple Systems with Event Codes data. The tab provides a summary of all systems that have a fix recorded for each failure mode.
