Definition:

For the purposes of this course:

The terms Asset, Hardware, andItem

are used interchangeably to describe the

equipment under analysis

6/20

Definition:

HARDWARE PARTITION

A logical hierarchical division of an asset into

progressively lower levels to show relationships

among systems, subsystems, components, etc.

Also called EQUIPMENT HIERARCHY or

HARDWARE BREAKDOWN

Partition may use any logical system:

CMMS Work Unit Code

Maintenance/Operators manuals

OEM Parts breakdown

Physical boundaries

Considerations: Partitioning

HARDWARE PARTITIONING

7/28/2019 C2-3(HW).ppt

11/20

Hardware Partitioning Considerations/Suggestions: Must be a physical partition:

Each item should only be in one branch of the hierarchy

Consider how failure data is recorded

Manuals may provide logical divisions of equipment Boundaries should be clearly identified:

List specific valves, terminal blocks, etc. that end one system

and begin another

Boundaries should take into consideration functions of

equipment

General boundary statements can be used Be prepared to adjust boundaries:

During an analysis, better partitioning may become evident,

especially when defining functions

Partition one level below where the analysis will be performed:

Provides helpful information during the analysis

Considerations: Partitioning

HARDWARE PARTITIONING

12/20

Identification:

Hardware Partition should include a Numbering or

Identification System

Uniquely identifies each system, sub-system, etc.

Should identify relationships between parent and

child items

Can use existing system or create a new one:

CMMS scheme

Equipment Identification Numbers

Military: WUC, Logistics Control Number, etc.

What level to perform RCM analysis?

System or Subsystem level is usually thebest starting point

Complexity or other factors may warrant

a lower or higher level

Different levels can be used within same

analysis

Consider on-equipment maintenance

level

Level of Analysis: Partitioning

HARDWARE PARTITIONING

14/20

System/Subsystem Analysis:

Most efficient for a large scale analysis effort

Reduces number of functions to identify Secondary functions are easier to identify

Aids in proper effects determination

Aids in identification of significant failure

modes

Allows combination of failure modes where it

makes sense

Helps focus maintenance tasks on preservation

of system/end item operation

Component level analysis:

Most effective for limited analysis of a fewspecific hardware items or failure modes

Also useful for analysis of components used

on multiple systems

Hardware partition should provide boundary

definitions that eliminate confusion over what is/is

not included in analysis

Examples:

Piping or tubing

Controls

Air or water supply sources

Brackets, fixtures, or attach points
