General Reference

ACA Data Model

An ACA is composed of entity families, relationship families, and business rules. The workspaces in the ACA interface provide you with a custom view of ACA records that exist in the database. These pages also help to facilitate the creation of new records.

The ACA data model uses families to represent the various components of an ACA, and leverages the GE Digital APM fundamental entity and relationship family infrastructure to store data related to an ACA. The ACA interface is simply a customized view of individual records that make up an ACA.

All ACAs begin with an ACA record. Each ACA record is linked to:

One or more Human Resource records
One or more Reference Document records
One or more ACA System records

Each ACA System record is linked to:

One or more Equipment or Functional Location records
One or more Meridium General Recommendation records
One Risk Assessment record

The ACA System family contains Asset Groups that are made up of Equipment and Functional Location records, and they can participate in additional relationships when integrated with modules within the Asset Strategy work process.

ACA Data Model

The following diagram illustrates the families that participate in an ACA.

The boxes represent entity families, and the arrows represent relationship families. You can determine the cardinality of a relationship from the direction of the arrow (i.e., the arrow points to the successor family).

For example, ACA System records are linked to Risk Assessment records through the Has Risk relationship, where the ACA System family is the predecessor.

In this diagram, the Equipment and Functional Location families represent the equipment and locations that are involved in the ACA.

ACA Data Model Integrated with Asset Strategy

Depending on the licenses that have been activated in your database, you can promote records from ACA to the following modules in the Asset Strategy work process:

Reliability Centered Maintenance (RCM)
Failure Modes and Effects Analysis (FMEA)
Asset Strategy Management (ASM)

Throughout the ACA documentation, we assume that the ASM, RCM, and FMEA modules are active.

The following diagrams illustrate the families that participate in the integration between ACA and RCM, FMEA, and ASM.

The boxes represent entity families, and the arrows represent relationship families. You can determine the cardinality of a relationship from the direction of the arrow (i.e., the arrow points to the successor family).

RCM/FMEA Integration with ACA

The RCM and FMEA modules use the same families, so the following diagram illustrates how families in the ACA data model are related to families in the RCM and FMEA data models.

ASM Integration with ACA

The following diagram illustrates how families in the ACA data model are related to families in the ASM data model.

ACA Security Groups and Roles

The following table lists the baseline Security Groups available for users within this module, as well as the baseline Roles to which those Security Groups are assigned.

Important: Assigning a Security User to a Role grants that user the privileges associated with all of the Security Groups that are assigned to that Role. To avoid granting a Security User unintended privileges, before assigning a Security User to a Role, be sure to review all of the privileges associated with the Security Groups assigned to that Role. Also, be aware that additional Roles, as well as Security Groups assigned to existing Roles, can be added via Security Manager.


Security Group	Roles
MI ACA Administrator	MI Foundation Admin
MI ACA Member	MI Foundation Admin MI Foundation Power MI Foundation User MI APM Viewer
MI ACA Owner	MI Foundation Admin MI Foundation Power

The baseline family-level privileges that exist for these Security Groups are summarized in the following table.

Equipment, Locations, and ACA Systems

Each ACA system can be linked to:

Only Equipment.: Use this option if you want to evaluate the criticality of only pieces of equipment that are not moved between locations.

-or-
Only Functional Location.: Use this option if you want to evaluate the criticality of only pieces of equipment that are often replaced with other pieces of equipment.

-or-
Equipment and Functional Location.: Use this option if you want to evaluate the criticality of both pieces of equipment that are not moved between locations, and pieces of equipment that are often replaced with other pieces of equipment.

In the baseline database, the ACA System family is related to the:

Asset Group through the Group Has ACA System relationship family.

Furthermore, the Asset Group family is related to the:

Equipment family through the Group Has Asset relationship family.
Functional Location family through the Group Has Asset relationship family.

These relationships are illustrated in the ACA data model.

About the ACA Unmitigated Risk Graph

When you access an ACA, in the Overview section, the Unmitigated Risk graph displays the unmitigated risk value for each system that is associated with that ACA.

If you select one of the system nodes associated with that ACA, in the left pane, in that system's Overview section, the Unmitigated Risk graph displays the unmitigated value for each Equipment and Functional Location record that is associated with that system.

In this way, you can drill down into a series in the ACA Unmitigated Risk graph to view the unmitigated risk value for the records that appear on a subsequent row in the grid on the Asset Criticality Analysis page.

When you view the ACA Unmitigated Risk graph for a system, it might look similar to the following image.

About the ACA Analyses by State Graph

When you access an ACA Analyses by State graph, in the Overview section, the graph displays the number of Analyses and the states of the Analyses.

ACA Analyses by State graph plots the number of ACA Analyses in the database with the corresponding Analysis state: Planning, Active, Review, Pending Approval, and Complete. This plot is a distribution of ACA Analyses that are related to the selected hierarchy level.

When you view the ACA Analyses by State graph for a system, it might look similar to the following image.

About the Asset Criticality Distribution Graph

When you access an Asset Criticality Distribution Graph, in the Overview section, the graph displays a breakdown of the numbers of pieces of equipment in the database that are ranked based on the risk.

Asset Criticality Distribution graph plots the number of pieces of equipment in the database with the corresponding risk rank values. This plot is a distribution of Asset Criticality that is related to the selected hierarchy level.

When you view the Asset Criticality Distribution graph for a system, it might look similar to the following image.

ACA State Configuration

This topic describes attributes of the State Configuration that is defined for the ACA family in the baseline GE Digital APM database.

States and Operations

The following diagram illustrates the State Configuration that is defined for the ACA family. The boxes represent states, and the arrows represent operations. You can determine the cardinality of an operation from the direction of the arrow (i.e., the state to which the arrow points is the successor state).

Initial State

The Planning state is the initial state of all new ACA records.

Datasheet Configuration

By default, states and operations will appear on the datasheet when you are viewing an ACA record.

Reserved States and Operations

By default, all states and operations displayed in the diagram are reserved. This means that you cannot remove or modify any of these states or operations. You can, however, add your own states and operations to the State Configuration.

State Configuration Roles

By default, the MI ACA Owner State Configuration Role is assigned to all predecessor and successor states in the ACA State Configuration. You can assign other State Configuration Roles to any state. In addition, for each state, the Require a specific user to be assigned to a state check box is selected.

About Site Filtering in ACA

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

Site filtering in ACA is achieved by specifying a value in the Site Reference Key for a record. Users must have privileges for the relevant site to access records with a specified site. Users can be assigned to one or many sites. They will be able to view global data, as well as view data for each of the sites to which they are assigned.

Site filtering behavior is applied to all areas where data is handled in ACA including data loaders, asset hierarchy, global search, and queries throughout the ACA module.

In ACA, site filtering affects the following records:

ACA Record: If an ACA record is assigned to the default site, only by users who have been assigned to the same site can access the record.
ACA System Record: For an ACA system record, the site is inherited from the ACA.
Equipment and Functional Location Records: The records are filtered and displayed based on the site value inherited from the user.

Example: ACA Records

Consider a user who has access to Site X, Site Y, and Site Z. The user creates an analysis, ACA 1, which is not assigned to any site. ACA 1 is a global record, and contains the following records:

ACA System, which inherits the site value from ACA 1
FL1, which is assigned to Site X
FL2, which is assigned to Site Y
FL3, which is assigned to Site Z
EQ1, which is assigned to Site X
EQ2, which is assigned to Site Y
EQ3, which is assigned to Site Z

Scenario 1: User assigned to only Site X

When a user who is assigned to only Site X views ACA 1, he or she will see the following records:

FL1, which is assigned to Site X
EQ1, which is assigned to Site X

The records for Site Y or Site Z will not appear for a user assigned to Site X. The user sees data for the assigned Site X.

Scenario 2: User assigned to Site X and Site Y

When a user who is assigned to Site X and Site Y views ACA 1, he or she will see the following records:

FL1, which is assigned to Site X
EQ1, which is assigned to Site X
FL2, which is assigned to Site Y
EQ2, which is assigned to Site Y

The records for Site Z will not appear for a user assigned to Site X and Site Y. The user sees data for both the assigned sites as well as global data.

Scenario 3: Super User

If a Super User views ACA 1, he or she will see the following records:

FL1, which is assigned to Site X
FL2, which is assigned to Site Y
FL3, which is assigned to Site Z
EQ1, which is assigned to Site X
EQ2, which is assigned to Site Y
EQ3, which is assigned to Site Z

Important: A Super User can change the site to any of the sites that the user has permission for or choose to make the ACA record as a Global Record, so that all the GE Digital APM users can see it.

ACA Components

An ACA is composed of an ACA record, and all the records that are linked directly and indirectly to it. Refer to the data model for details on how these records are linked in the GE Digital APM database.

An ACA includes an ACA record, and records in the following families:

Human Resource : Stores details about the team members participating in the analysis.
Reference Document : Stores hyperlinks to documents that are external to GE Digital APM (e.g., a diagram) that the team can use during the analysis.
Asset Criticality Analysis System : Stores details about the systems in your facility for which you are conducting the analysis.

In addition to the records listed above, an ACA includes records in the following families that are linked directly to an Asset Criticality Analysis System record through the Asset Criticality Analysis Has System relationship family.

General Recommendation : Stores details on recommendations that have been proposed by the ACA team to mitigate the risk of a system or asset failure.
Risk Assessment : Stores the unmitigated risk value for the system or asset that you are analyzing.
Equipment and Functional Location : Stores details on equipment and locations, which are part of Asset Groups, and that are included in the system that is represented by the ACA System record.
