System Reliability Data Model

The following diagram shows how the families used in System Reliability Analysis are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of the each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

In the above image:

  • Black arrows and boxes represent entity families, relationship families, and associated relationship definitions that are configured in the baseline database and do not require customization for the baseline functionality to work.
  • Red arrows and boxes represent entity families, relationship families, and associated relationship definitions that may require customization.
  • The System Action box represents one of four System Action subfamilies in which records can exist: System Condition Monitor, System Inspection, System Preventive Maintenance, or System Special Action. The specific family that is used will depend upon the type of Action that is created for a given Asset or Switch element.
  • The Distribution box represents one of four Distribution subfamilies in which records can exist: Exponential, Lognormal, Normal, or Weibull record. The specific family that is used will depend upon the distribution type selected for the associated Risk.

Throughout this documentation, we use the term System Reliability Analysis to mean the combination of the root System Analysis record and all records that are linked to it.

About Site Filtering in System Reliability Analysis

In System Reliability Analysis, the site is assigned based on the user's selection in the Site control, and all data added or imported to the System Reliability Analysis must match the analysis's site assignment.

Tip: For more information, refer to the Site Filtering section of the documentation.

In System Reliability Analysis, Rules, users will see only data that is assigned to their site(s) or that is global data.

Consider an organization that has three sites, Site X, Site Y, and Site Z. The following System Reliability Analysis records exist:

  • System Reliability Analysis A: Assigned to Site X
  • System Reliability Analysis B: Assigned to Site Y
  • System Reliability Analysis C: Assigned to Site Z
  • System Reliability Analysis D: No site assigned (global record)

Scenario 1: User assigned to only Site X

This user will see System Reliability Analyses A and D.

Scenario 2: User assigned to both Site X and Site Y

This user will see System Reliability Analyses A, B, and D.

Scenario 3: Super User

This user will see System Reliability Analyses A, B, C, and D.

Important: If a multi-site user, or a Super User, links child records from multiple sites to a parent record designated as Global, another user who does not have access to all sites may only see a portion of the data associated with that record.

System Action Families

This topic provides a listing of all the System Action families with links to the family fields information.

System Special Action Records

System Special Action records store information about procedural, redesign, or training Actions. The following table provides an alphabetical list and description of the fields that exist for the System Special Action family and appear by default on the System Special Action 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 then 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 Site Filtering section of the documentation.

Field CaptionData TypeDescriptionBehavior 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 of the Properties pane.

Action 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 Special Action record:

  • Procedure (PROC)
  • Redesign (DSN)
  • Training (TRN)

After you create an Action, this field is disabled.

This field is available in the General section of the Properties pane.

Description TextA text field that stores any additional information about the Action.

You can define this value manually by entering text in the Description box.

This field is available in the General section of the Properties pane.

Duration Number

A numeric value that, combined with the value in the Duration Units field, identifies the total time nedeed 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 Special 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, this value is set to Days. This field is available in the Special 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 GE Digital APM system and does not appear on the System Special Action datasheet. In System Reliability Analyses, GUIDs are used to identify records because Entity Keys will not exist until a record is saved. Because 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 Special 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, this value is set to Days. This field is available in the Special section of the Properties pane.

Name Character The name of the Action.

You can define this field manually. This value is used to identify Actions in the System Reliability Analyses. For instance, 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.

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 Special Action 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 Special Action record would be selected. By default, this check box is selected.

This field is available in the Special 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 selected.

This field is available in the Special section of the Properties pane.

System Preventive Maintenance Records

System Preventative Maintenance records store information about time-based maintenance Actions. The following table provides an alphabetical list and description of the fields that exist for the System Preventative Maintenance family and appear by default on the System Preventative Maintenance datasheet.

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 selected.

This field is available in the Preventive Maintenance 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 then 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 Site Filtering section of the documentation.

Field CaptionData TypeDescriptionBehavior and Usage

Description TextA 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.

Failures Without Replacement LogicalIndicates 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 NumberIndicates 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 LogicalIndicates 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 DateIndicates 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 CharacterThe 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 NumberThe 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 NumberA 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 NumberThe 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 CharacterThe 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

Planned Correction Cost

NumberThe 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 NumberThe time nedeed to implement a planned correction. By default, this field contains the value 0.
Planned Correction Duration Units CharacterThe 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

Repair Immediately LogicalA 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 NumberA 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 CharacterThe 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:

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.

Max Advance Duration Units

CharacterThe time units associated with the value in the Max Advance Duration field.

You can select a value from the following options:

  • Hours
  • Days
  • Weeks
  • Months
  • Years
Max Delay Duration Number

A numeric value that identifies the maximum time that an Action can be delayed to be completed with the other Actions that are assigned to the Global Event.

For example, if the Max Delay Duration field contains the value 2 and the Max Advance Duration Units field contains the value Weeks, then any Action that would be performed 2 weeks or less before the Global Event can be delayed in time and completed with the rest of the Actions that are assigned to a Global Event.

By default, this value is set to 0 (zero).
Max Delay Duration Units CharacterThe time units associated with the value in the Max Delay Duration field.

You can select a value from the following options:

  • Hours
  • Days
  • Weeks
  • Months
  • Years
Name CharacterThe 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 LogicalIndicates 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.

System Buffer Records

System Buffer records store information about buffers that exist in the System Analysis diagram. The following table provides an alphabetical list and description of the fields that exist for the System Buffer family and appear by default on the System Buffer 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 then 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 Site Filtering section of the documentation.

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 BinaryA field that is used internally by the GE Digital 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 DateThe 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 NumberA 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 BinaryA field that is used internally by the GE Digital 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.

Cost Trend Plot BinaryA field that is used internally by the GE Digital APM system to store the image of the Total Cost Trend 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.

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 TextA 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.
Period Units CharacterThe time units associated with the value in the Period field.

You can select a value from one of the following options:

  • Hours
  • Days
  • Weeks
  • Months
  • Years
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 BinaryA field that is used internally by the GE Digital 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.

About Show Total Check Box

The Show Total check box is a feature that is available on the following System Reliability Analysis results plots:

  • Total Cost plot
  • Annual Action Cost plot
  • Resource Cost plot

In these graphs, each column represents a separate Scenario. The Show Total check box determines how the columns are displayed, as described in the following list:

  • When the Show Total check box is cleared, the plots display one column that is divided into sections representing the individual cost types or resources within that Scenario. In addition, the legend displays labels for the individual categories that are represented in each column.
  • When the Show Total check box is selected, the plots display one column that is not divided into sections but instead displays the total cost associated with all categories in that Scenario. In addition, the legend displays the label Total.

The following image shows the Total Cost plot for our System Reliability Analysis Example when the Show Total check box is selected.

The following image, on the other hand, shows the Total Cost plot for our System Reliability Analysis Example when the Show Total check box is cleared.

About Simulation Period

Some results of a System Reliability Analysis are presented according to the simulation period that you have selected. The simulation period is defined by the values in the System Analysis record:

  • The values in the two Period boxes. The Period boxes represent the Period and Period Units fields in the System Analysis record and determine the length of the simulation.
  • The value in the Time Analysis Type box. The Time Analysis Type box represents the Time Analysis Type field in the System Analysis record, and the value determines whether results are calculated for each year or each month of the simulation. If the Time Analysis Type is set to:
    • Yearly, the graphs display values for each year included in the simulation period, which is defined by the values in the Period, Period Units, and Analysis Start Date fields in the System Analysis record.
    • Monthly, the graphs display values for each month included in the simulation period, which is determined by the values in the Period, Period Units, and Analysis Start Date fields in the System Analysis record.

About Average Total

The average total is the average of all the totals across all iterations of a simulation, which is calculated by the GE Digital APM system for each simulation. Average totals are calculated for various types of numeric values in a simulation, such as cost in the Total Cost Trend plot or time in the Resource Time plot.

About Interpreting Simulation Results That Include Source and Additional Risks

The results for a simulation will appear differently depending on whether or not the simulation includes source and additional Risks. It is important that you understand how to interpret simulation results that include source and additional Risks. This documentation assumes that you are familiar with System Risk records and their role in a System Reliability Analysis.

When you set up a simulation to include source and additional Risks, you should consider the following information:

  • If an unplanned correction causes a source Risk and any additional Risks to be reset, in the simulation results, the Failure associated with the unplanned correction of the source Risk will be attributed only to the source Risk.
  • If a planned correction of a source Risk results in additional Risks being reset, in the simulation results, the following values will be attributed to each individual Risk:
    • Planned Correction Cost
    • Planned Resource Usages
    • Downtime

    Downtime for each Risk will be calculated based on the planned correction duration for that Risk.

  • If an unplanned correction of a source Risk results in additional Risks being reset, in the simulation results, the following values will be attributed to each individual Risk:
    • Fixed Unplanned Correction Cost
    • Variable Unplanned Correction Cost
    • Unplanned Resource Usagess
    • Downtime

    Variable unplanned correction cost and downtime for each Risk will be calculated based on the TTR distribution for that Risk.

  • If planned or unplanned correction of a source Risk results in additional Risks being reset, in the simulation results, the Equipment or Functional Location record to which the System Risk records are linked will be populated with the largest downtime value of all the Risks (i.e. source and additional). For example, suppose that the following Risks are defined for a Water Pump:
    • A Bearing failure Risk that is a source Risk and whose downtime value is 1 day.
    • A Seal failure Risk that is an additional Risk and whose downtime value is 2 days.

    In this case, when the Bearing failure Risk resets the Seal failure Risk, in the simulation results, a downtime value of 2 days will be attributed to the Water Pump.

  • If planned or unplanned correction has started for an additional Risk, and then, planned or unplanned correction starts for the source Risk that resets that additional Risk, the additional Risk will be reset only once, as a result of its own planned or unplanned correction. The additional Risk will not be reset two times as a result of its own planned or unplanned correction and the planned or unplanned correction of the source Risk. This will be reflected in the simulation results.

About Impact Plot

The Impact Plot provides visual representation of the average values that are combined to make up the average value of the result that you selected in the grid.

The Impact Plot displays how the average failure value is calculated as a total of the individual Risk failure averages.

Note:

The Impact Plot is not available for the Actions and Resources tab.

About Trend Plot

The Trend Plot provides the average value for each analysis time interval, as defined by the value in the Time Analysis Type field in the root System Analysis record, of the result that you selected in the grid.

If the Time Analysis Type field is set to:

  • Yearly, the Cost Trend Plot will display the Cost Trend for each year in the simulation period.
  • Monthly, the Cost Trend Plot will display the Cost Trend for each month in the simulation period.

Note: Interaction with graphs is not available on touch-screen devices.

About Histogram Plot

The Histogram Plot provides a visual representation of the frequency distribution of the result that you selected in the grid in the Elements section.

Note: Interaction with graphs is not available on touch-screen devices.

Details

The Histogram Plot shows the distribution of the actual values from all iterations that were used to calculate the average value. The distribution of the actual values spreads across a series of data ranges, which are called bins and are represented by columns on the Histogram Plot. When an actual value from an iteration falls into a bin, it is included in the associated column. The higher the column is, the more values have fallen into the bin.

Note: The number of columns that appear in the Histogram Plot is determined by the value in the Histogram Bins field in the root System analysis.

Additional values are represented by the following lines in the Histogram Plot:

About Resource Occurrence Graph

The Resource Occurrence graph displays statistics about the total use of each Resource when the value in the Count Occurrence field of the associated System Resource record is set to True. The Resource occurrence count is calculated from the average total usage across all iterations.

Note: For System Resource records where the Count Occurrence field is set to False, the occurrence count of that Resource will be zero, and it will not be displayed on the graph. The Mechanic Resource, whose Count Occurrence field value is False, does not appear on the Resource Occurrence graph but is still used in the simulation and appears in both the Resource Time graph and the Resource Cost graph.

About Results of a System Reliability Analysis

When you run a Monte Carlo simulation, the GE Digital APM system analyzes statistics about cost, performance, and reliability from the iterations of the analysis to calculate the simulation results. The simulation results display average values as well as the specific values that were used to calculate the averages.

What Can You Learn from a System Reliability Analysis?

By reviewing the results of a System Reliability Analysis, you will be able to answer questions such as:

  • Which Scenario has the lowest overall cost associated with it?
  • Which Scenario is the least reliable?
  • Which Scenario has the highest failure rate?
  • Which Actions were successful in mitigating risk and reducing cost?
  • How many times were Resources used?
  • How much did the Resources cost?
  • For how long were the Resources used?
  • How many times was an Action required?

After reviewing the results of a System Reliability Analysis, you can identify which Scenario consistently provides the best reliability and produces the least amount of downtime and cost. Based upon the results, you might decide to complete any of the following steps:

  • Refine the Scenarios by modifying the analysis parameters or components within the analysis or create new components to further analyze reliability and costs.
  • Create Recommendations to implement changes to the current physical system to align it with the most desirable Scenario.
