This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. For more information, refer to the Sites section of the documentation.


Field Caption	Data Type	Description	Behavior and Usage
Action Cost	Numeric	A numeric value that specifies the cost associated with any materials or personnel needed to complete an action.	This value represents an expense that is incurred every time the action occurs. By default, the value in this field is set to 0 (zero).
Acton Type	Character	The category into which the action can be classified.	You can select a value from the following options when you create the System Action record: Condition-Based Maintenance (Predictive) Procedure Redesign Time-Based Maintenance (Preventative) Training After you create an action, this field is disabled. The values in this field are populated by the MI_ACTION_TYPE System Code Table.

Condition Monitoring Type	Character	A field that contains a value indicating whether the Action occurs continuously or periodically at regular intervals.	By default, this value is set to Continuous. After you create an Action, this field is disabled. This field is available in the General section of the Properties pane.
Description	Text	A text field that stores any additional information about the Action.	You can enter text manually in the Description box. This field is available in the General section of the Properties pane.
Detection probability (%)	Number	A numeric value representing the probability that the Action will identify a potential failure resulting from any Risk and correct that failure before it occurs.	By default, this value is set to 100 by default. For an Action with no assigned Risks, any value stored in this field will be ignored. For example, a System Condition Monitor record with the Detection Probability value 50 has a 50% chance of identifying a potential failure resulting from a Risk. In other words, the Action will detect one out of two potential failures resulting from any Risks assigned to the Action. This field is available in the Condition Monitor section of the Properties pane.
GUID	Character	A value that uniquely identifies the record within a System Reliability Analysis.	This value is generated automatically by the APM system and does not appear on the System Condition Monitor datasheet. In System Reliability Analyses, GUIDs are used to identify records because Entity Keys will not exist until a record is saved. Since a System Reliability Analysis may contain unsaved records, it is necessary to use a value that uniquely identifies those records within the system.
Name	Character	The name of the Action.	You can define this value manually. This value is used to identify Actions in the System Reliability Analyses. For example, the Name column appears by default in the Actions tab in the workspace and displays values that exist in the Name field to identify the System Action records that are displayed in the workspace. This field is available in the General section of the Properties pane.

System Inspection Records

System Inspection records store information about periodic, condition-based maintenance Actions. The following table provides an alphabetical list and description of the fields that exist for the System Inspection family and appear by default on the System Inspection datasheet. The information in the table reflects the baseline state and behavior of these fields. This list is not comprehensive.

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. For more information, refer to the Sites section of the documentation.


Field Caption	Data Type	Description	Behavior and Usage
Action Cost	Number	A numeric value that specifies the cost associated with any materials or personnel needed to complete the Action.	This value represents an expense that is incurred every time the Action occurs. By default, this value is set to 0 (zero). This field is available in the General section in the Properties pane.
Action Type	Character	The category into which the Action can be classified.	By default, this value is set to Condition-Based Maintenance (Predictive) (CM). After you create an Action, this field is disabled. This field is available in the General section of the Properties pane.
Condition Monitoring Type	Character	A value that indicates whether the Action occurs continuously or periodically at regular intervals.	By default, this value is set to Periodic. After you create an Action, this field is disabled. This field is available in the General section of the Properties pane.
Description	Text	A text field that stores any additional information about the Action.	You can enter text manually in the Description box. This field is available in the General section of the Properties pane.
Detection Probability	Number	A numeric value representing the probability that the Action will identify a potential failure resulting from any Risk and correct that failure before it occurs.	By default, this value is set to 100. For an Action with no assigned Risks, any value stored in this field will be ignored. An Action can detect a potential failure only when the Action occurs during a Risk's PF Interval, as defined by the value in the PF Interval and PF Interval Units fields in the System Risk record. If the Action does not occur during the PF Interval, the Action cannot identify the potential failure, and the value in the Detection Probability field will be ignored. To make the Action occur during the PF Interval of a Risk, you can manually modify the values in the PF Interval and PF Interval Units fields of the System Risk record, or you can optimize the Action. For example, setting the Detection Probability to 50 would indicate that the Action has a 50% chance of identifying a potential failure resulting from any Risk if the Action occurs during the PF Interval of the Risks. In other words, the Action will detect one out of two potential failures resulting from any Risks assigned to the Action when the Action occurs during the PF Interval of the Risks. This field is available in the Inspection section of the Properties pane.
Duration	Number	A numeric value that, combined with the value in the Duration Units field, identifies the total time needed to complete the Action. For example, if the value in the Duration field is 4 and the value in the Duration Units field is Hours, then the Action will take four hours to complete.	By default, this value is set to 0 (zero). This field is available in the Inspection section of the Properties pane.
Duration Units	Character	The time units associated with the value in the Duration field.	You can select a value from the following options: Minutes Hours Days Weeks Months Years By default, the value in this field is set to Days. This field is available in the Inspection section of the Properties pane.
GUID	Character	A value that uniquely identifies the record within a System Reliability Analysis.	This value is generated automatically by the APM system and does not appear on the System Inspection datasheet. In System Reliability Analyses, GUIDs are used to identify records because Entity Keys will not exist until a record is saved. Since a System Reliability Analysis may contain unsaved records, it is necessary to use a value that uniquely identifies those records within the system.
Interval	Number	A numeric value that, combined with the value in the Interval Units field, indicates how often the Action will occur. For example, if the value in the Interval field is 4 and the value in the Interval Units field is Months, then the Action will occur every four months during the simulation period.	By default, this value is set to 1. This field is available in the Inspection section of the Properties pane.
Interval Units	Character	The time units associated with the value in the Interval field.	You can select a value from the following options: Minutes Hours Days Weeks Months Years By default, the value in this field is set to Days. This field is available in the Inspection section of the Properties pane.
Name	Character	The name of the Action.	You can define this value manually. This value is used to identify Actions in the System Reliability Analyses. For example, the Name column appears by default in the grid in the Actions section and displays values that exist in the Name field to identify the System Action records that are displayed in the grid. This field is available in the General section of the Properties pane.
One Time Action	Logical	Indicates whether the Action will occur one time or will be repeated more than once.	If this check box is selected, the Action will occur once. If this check box is cleared, the Action will occur more than once. For example, an Action to inspect the vibration level of a pump might occur several times a year. In this case, the One Time Action check box of the corresponding System Inspection record would be cleared. An Action to inspect a newly installed pump for any installation errors might occur only once, in which case the One Time Action check box of the corresponding System Inspection record would be selected. By default, this check box is cleared. This field is available in the Inspection section of the Properties pane.
Shutdown Required	Logical	Indicates whether the Action requires the piece of equipment or location to be shut down in order for the Action to be completed.	If this check box is selected, the piece of equipment or location must be shut down in order for the Action to be completed. If this check box is cleared, the Action can be completed while the piece of equipment or location is running. For example, an Action to inspect the vibration level of a pump could be completed while the pump is running, so the Shutdown Required check box would be cleared. An Action to inspect the internal components of a pump would be completed while the pump is not running, so the Shutdown Required check box would be selected. By default, this check box is cleared. This field is available in the Inspection section of the Properties pane.

Analysis End Date	Date	The date on which the analysis ends (i.e., when the simulation will stop running).	This value is calculated by adding the amount of time defined by the values in the Period and Period Units fields to the value in the Analysis Start Date field. This field is populated automatically. This field does not appear by default on the System Analysis datasheet.
Analysis Name	Character	A value that identifies the System Reliability Analysis throughout System Reliability.	This value is populated automatically with New Analysis 1. You can define this field manually. The Analysis Name field appears by default in the Definition section in the Analysis Summary workspace and displays values that exist in the Analysis Name field to identify the System Analysis records that are displayed in the grid. This field is labeled Name on the datasheet.
Analysis Result	Binary	A field that is used internally by the APM system to store the data that appears in the Elements, Actions, and Resources grids.	You should not modify the value in this field. Doing so will cause the analysis to become corrupt, and you will no longer be able to open it. This field does not appear by default on the System Analysis datasheet.
Analysis Start Date	Date	The first date of the analysis.	You can define this field manually. This field is labeled Start Date in the Definition section of the Analysis Summary workspace. The amount of time defined by the values in the Period and Period Units fields is added to the value in this field to determine how long the simulation will run. This field is labeled Start Date on the datasheet.
Confidence	Number	A numeric value that represents the confidence level of simulation results.	This value determines the Optimistic and Pessimistic values in the Histogram plot in the Simulation Results workspace. The default value for this field is 90. If you accept the default value, when you look at the Histogram plot, you will know that there is a 90% chance that the value in any cell in the grids in the Simulation Results workspace in the analysis lies within the range between the Optimistic and Pessimistic values. This field is labeled Confidence Level on the datasheet.
Cost Plot	Binary	A field that is used internally by the APM system to store the image of the Total Cost plot.	You should not modify the value in this field. Doing so will cause the analysis to become corrupt, and you will no longer be able to open it. This field does not appear by default on the System Analysis datasheet.

Currency	Character	The currency used to display financial results in various places throughout System Reliability.	This value is set to $ by default. The Cost column appears by default in the Elements section of the Simulation Results workspace. The value that exists in the Currency field is included in the Cost column header. For example, if you specify $ in the Currency field, the label for the Cost column will be Cost ($). This field is labeled Select Currency on the datasheet.
Description	Text	A text field that stores any additional information about the analysis.	You can define this value by entering text manually. This field is labeled Analysis Description on the datasheet.
Histogram Bins	Number	A numeric value that defines the number of bins, or columns, that will be displayed on the Histogram plot.	The default value for this field is 20. If you accept the default value, when you look at the Histogram plot on the Simulation Results workspace, there will be 20 bins on the Histogram plot.
Number of Iterations	Number	A numeric value that identifies the number of times the system will be simulated in order to compile simulation results.	In the simple Monte Carlo example provided in this documentation, one iteration represents a single roll of the dice. The more iterations you use in an analysis, the more reliable the simulation results will be. The default value for this field is 1,000. The value you specify in the Iterations field must be compatible with the value that you specify in the Confidence field. The required number of iterations is dependent on the confidence boundary, as defined by the value in the Confidence field. The following equation is used to determine the required number of iterations: Minimum Number of Iterations = 40/(1- Confidence Field Value) In other words, the number of iterations must be high enough to provide a statistically significant confidence level. For example, a System Reliability Analysis with a value of 90 in the Confidence field would require a value of at least 400 in the Iterations field, as shown in the following calculation: Minimum Number of Iterations = 40/(1-90%) Minimum Number of Iterations = 40/.1 Minimum Number of Iterations = 400 If you enter a value in the Iterations field that is below the desired value, an error message will appear, and you will be required to specify another value before you can save the analysis.
Period	Number	A numeric value that identifies the time period over which an analysis occurs.	By default, this value is set to 1. The value in the Period Units field determines the time units that will be applied to the value in the Period field.

Random Seed	Logical	Indicates whether or not different random numbers will be used for the system-generated inputs for each run of the simulation so that different results are returned each time.	By default, this value is set to False. If the Random Seed field is set to True, different inputs will be used for each simulation so that different results will be generated each time the simulation is run even if you have made no changes to the analysis. If the Random Seed field is set to False, the same results will be generated each time you run the simulation, provided that you have made no changes to the analysis. This field is labeled Enable Random Seed on the datasheet.
Resource Cost Plot	Binary	A field that is used internally by the APM system to store the image of the Resource Cost plot.	You should not modify the value in this field. Doing so will cause the analysis to become corrupt, and you will no longer be able to open it. This field does not appear by default on the System Analysis datasheet.
Resource Occurrence Plot	Binary	A field that is used internally by the APM system to store the image of the Resource Occurrence plot.	You should not modify the value in this field. Doing so will cause the analysis to become corrupt, and you will no longer be able to open it. This field does not appear by default on the System Analysis datasheet.
Time Analysis Type	Character	A field whose value determines how results are displayed in the Total Cost Trend Plot and Trend Plot.	By default, this value is Yearly. If this field is set to Yearly, the x-axis will display results for every year in the simulation period. If this field is set to Monthly, the x-axis will display results for every month in the simulation period.
Visual Attributes	Text	A field that is used internally by APM and stores visual information, such as chart settings and diagram positioning.	You should not modify the value in this field. Doing so will cause the analysis to become corrupt, and you will no longer be able to open it. This field does not appear by default on the System Analysis datasheet.

GUID	Character	A value that uniquely identifies the record within a System Reliability Analysis.	This value is generated automatically by the APM system. In System Reliability Analyses, GUIDs are used to identify records because Entity Keys will not exist until a record is saved. Since a System Reliability Analysis may contain unsaved records, it is necessary to use a value that uniquely identifies those records within the system. This field does not appear on the System Global Event datasheet.
Interval	Number	A numeric value that indicates how often the Global Event will occur. For example, if the value in the Interval field is 4 and the value Months exists in the Interval Units field, then the Global Event will occur every 4 months during the simulation period.	This field is enabled only if the value in the Driver Type field is Date Driven and the One Time Event check box is cleared.
Interval Units	Character	The time units associated with the value in the Interval field.	You can select a value from the following options: Hours Days Weeks Months Years
Max Advance Duration	Number	A numeric value that identifies the maximum time that an Action can be advanced forward to be completed with the other Actions assigned to the Global Event. For example, if the Max Advance Duration field contains the value 3 and the Max Advance Duration Units field contains the value Months, then any Action that would be performed 3 months or less after the Global Event can be moved forward in time and completed with the rest of the Actions that are assigned to the Global Event.	This value is set to 0 (zero) by default.

Name	Character	The name of the Global Event.	You can define this value manually. This value is used to identify Global Events in System Reliability Analyses.
One Time Event	Logical	Indicates whether the Global Event will occur one time or can be repeated more than once.	If this check box is selected, the Global Event will occur once. If this check box is cleared, the Global Event will occur more than once. For example, you might create an Action to replace an expensive piece of machinery. If the Action requires a complete shutdown, to reduce total downtime of the system, you could create a one-time Global Event with the One Time Event check box selected that would reschedule any assigned Actions to be completed during the desired shutdown. In contrast, Actions that are repeated several times would be assigned to a recurring Global Event with the One Time Event check box cleared because the Global Event would be needed several times to minimize downtime in a simulation period.

The following table provides an alphabetical list and description of the fields that exist for the System Risk family and appear on the System Risk datasheet by default. The information in the table reflects the baseline state and behavior of these fields. This list is not comprehensive.

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. For more information, refer to the Sites section of the documentation.


Field Caption	Data Type	Description	Behavior and Usage
Description	text	Additional information that is used to identify the Risk.	You can enter a description of the Risk into this field manually. This field appears in the General section.
Failures Without Replacement	Logical	Indicates whether or not the piece of equipment or location is replaced after each failure that results from the Risk.	By default, this check box is cleared. If this check box is selected, the piece of equipment or location is not replaced after each failure (as good as old). If this check box is cleared, the piece of equipment or location is replaced after each failure (as good as new).
Fixed Unplanned Correction Cost	Number	Indicates the set cost of a piece of equipment or location when it fails as a result of the Risk. Fixed cost does not change as a result of other variables, such as downtime. An example of fixed unplanned correction cost is the cost of a new piece of equipment.	By default, this field contains the value 0. This field appears in the Correction section.
Is Active	Logical	Indicates whether or not the piece of equipment's or location's operating time accumulates while the system is running. After a potential failure is detected, this value indicates whether the piece of equipment's or location's remaining life is reduced when the system is active or latent.	This value is a characteristic of the piece of equipment or location to which the Risk is related and should be the same for all Risks related to the same piece of equipment or location. By default, this check box is selected. If the check box is selected, the piece of equipment's or location's operating time will accumulate while the system is running, and the Is Latent check box should be cleared. This means that the v or location will lose lifetime while the system is running. For example, when a car (i.e., the system) is moving, a tire's (i.e., piece of equipment's) lifetime is being used up. The tire is active. This field is available in the Simulations Options section.
Is Latent	Logical	Indicates whether or not the piece of equipment's or location's operating time accumulates while the system is idle. After a potential failure is detected, this value indicates whether the piece of equipment's or location's remaining life is reduced when the system is active or latent.	This value is a characteristic of the piece of equipment or location to which the Risk is related and should be the same for all Risks related to the same piece of equipment or location. By default, this check box is cleared. If check box is selected, the piece of equipment's or location's operating time will accumulate while the system is idle, and the Is Active check box should be cleared. This means the piece of equipment or location will lose lifetime when the system is not running. For example, when a car (i.e., the system) is idle and not being used, failures can occur that will affect the hydraulic braking system (i.e., piece of equipment's). The rate of these failures is not impacted by the car being used or being idle, and is therefore latent in nature.
Last Failure	Date	Indicates the most recent date that the piece of equipment or location failed due to the Risk.	You can use the Calendar tool to select the date of the most recent equipment or location replacement.
Name	Character	The name of the Risk.	You can enter the name of the Risk in this field manually. This value is used to identify Risks in the System Reliability Analysis.
Number of Subcomponents	Number	The number of subcomponents to which the Risk applies.	By default, this field contains the value 1. The value should be greater than 1 only if the Failure Without Replacement check box is selected.
Percentage of PF Interval to Wait	Number	A numeric value that indicates how long to wait to repair the piece of equipment or location after detecting a potential failure due to this Risk.	By default, this field contains the value 0 and should be used only if the Repair Immediately check box is cleared. This value indicates at what percentage of the value in the PF Interval field the piece of equipment or location should be repaired. For example, an engineer monitors a Risk more frequently after a potential failure is detected and does not want to repair the piece of equipment or location immediately. If a potential failure is detected at the start of the PF Interval, and the engineer knows that the piece of equipment or location will not actually fail for 10 more days (i.e., a PF Interval of 10), he might decide to initiate a repair strategy six days later, or at 60 percent of the PF Interval. In this case, the Percentage of PF Interval to Wait is 60 percent.
PF Interval	Number	The time between when a potential failure is detectable and when an actual failure will occur.	By default, this field contains the value 0. This value is used along with the value in the Percentage of PF Interval to Wait field to determine when a piece of equipment or location should be repaired after a failure. The P-F Interval is determined by the user and is not calculated by the system.
PF Interval Units	Character	The time units associated with the PF Interval.	by default, this value is set to Days. You can select from a list of the following options: Minutes Hours Days Weeks Months Years
Planned Correction Cost	Number	The total cost (i.e., fixed cost plus variable cost) of a planned correction that will prevent the Risk from resulting in a functional failure. An example of a planned correction is a routine equipment cleaning.	By default, this field contains the value 0. A planned correction does not happen as a result of a failure.
Planned Correction Duration	Number	The time needed to implement a planned correction.	By default, this field contains the value 0.
Planned Correction Duration Units	Character	The time units associated with the Planned Correction Duration.	By default, this value is set to Days. You can select from a list of the following options: Hours Days Weeks Months Years
Repair Immediately	Logical	A value that indicates whether or not the piece of equipment or location should be repaired immediately if a potential failure due to this Risk is detected.	By default, this check box is selected. If the check box is selected, the piece of equipment or location should be repaired as soon as an inspection detects a failure, regardless of the remaining life of the piece of equipment or location. If the check box is cleared, the piece of equipment or location should be repaired according to the value in the Percentage of PF Interval to Wait field.
Variable Unplanned Correction Cost	Number	A number that indicates the variable cost associated with the downtime of an piece of equipment or location when it fails due to the Risk. An example of variable unplanned correction cost is the cost of labor per time period of the mechanic that repairs the piece of equipment or location.	By default, this field contains the value 0.
Variable Unplanned Correction Cost Units	Character	The time units associated with the Variable Unplanned Correction Cost.	By default, this value is set to Per Day. You can select from a list of the following options: Per Hour Per Day Per Week Per Month Per Year
