Abstract

Keeping a BDI on your Assets.

Body

Maximo Asset Configuration Manager (ACM) is designed to manage the configuration management requirements of complex assets operating in the aerospace, defence and rail sectors where safety and regulatory compliance is of primary importance.


One of the central components of Maximo ACM is the Build Data Interpreter (BDI). At it's most basic level the BDI analyses configuration managed Assets position by position to ensure that they comply with the configuration rules established in the corresponding model.

That said the BDI is a pretty complex process and tasked with processing large amounts of Assets with complex rules and configurations performance can degrade.

 
The Maximo ACM 7.5 release introduced a number of enhancements to address performance with particular emphasis on the BDI. One of the primary improvements, to achieve greater scalability, was to allow the BDI to run multiple instances in parallel.

This is achieved by setting up multiple instances of the BDI Cron Task within the Cron Task Setup application.

The Continuous mode of the BDI cron task checks compliance whenever you perform an update that could potentially affect the status of an configuration-managed asset.

The End Item mode of the BDI cron task ensures that the BDI checks the compliance of every end item asset at least once a day.

As can be seen in the image below multiple instances of both types of BDI Cron Tasks can be configured and there is additional logic to ensure they do not clash or perform unnecessary processing.

Also several new Cron Task Parameters have been introduced to allow increased control over the work the BDI Cron Tasks perform:

SiteID: Allows a Cron Task to be configured to run for a specific Maximo site.

ProcessMode: Allows the user to decide whether the BDI should validate the Asset against all possible configurations or just its current one.

ProcessMaintenancePlan: Controls whether any related maintenance plans for the Asset are analysed and acted upon.

These multiple instances can be spread across dedicated servers to ensure timely processing of transactions which can affect the status of a configuration managed Asset.In addition to these scalability improvements additional configuration options have been introduced in the Models (CM) application. This allows the user finer control over the work the BDI performs.

 

1. Configurable Map Code Processing.

At the Model level individual status codes that the BDI validates can be be made inactive to prevent unnecessary checking depending on client business requirements.

2. Configurable Node Level Processing.

Within the Build Hierarchy and Position Rules it is now possible to disable BDI validation for individual nodes (and their children) within the build hierarchy:

In addition to the performance and scalability improvements described there is also increased visibility of the work the BDI undertakes via the BDI Queue Status (CM) application.  This application gives a list of Assets the BDI is processing, has processed or is currently waiting to process.

I hope this gives you a flavour of some of the improvements we've incorporated as part of our Maximo 7.5 release. In short there's never been a better time to use ACM to manage your complex Assets!
