Definition:Definition: For the purposes of this course: The terms “Asset”, “Hardware”, and Item” are used interchangeably to describe the equipment under analysis PartitioningPartitioning HARDWARE PARTITIONING

Definition: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 PartitioningPartitioning HARDWARE PARTITIONING

Partition may use any logical system: CMMS CMMS Work Unit Code Work Unit Code Maintenance/Operators manuals Maintenance/Operators manuals OEM Parts breakdown OEM Parts breakdown Physical boundaries Physical boundaries Considerations:Considerations:PartitioningPartitioning HARDWARE PARTITIONING

Hardware Partitioning Considerations/Suggestions: Must be a physical partition: Must be a physical partition: Each item should only be in one branch of the hierarchy Each item should only be in one branch of the hierarchy Consider how failure data is recorded Consider how failure data is recorded Manuals may provide logical divisions of equipment Manuals may provide logical divisions of equipment Boundaries should be clearly identified: Boundaries should be clearly identified: List specific valves, terminal blocks, etc. that end one system and begin another List specific valves, terminal blocks, etc. that end one system and begin another Boundaries should take into consideration functions of equipment Boundaries should take into consideration functions of equipment General boundary statements can be used General boundary statements can be used Be prepared to adjust boundaries: Be prepared to adjust boundaries: During an analysis, better partitioning may become evident, especially when defining functions During an analysis, better partitioning may become evident, especially when defining functions Partition one level below where the analysis will be performed: Partition one level below where the analysis will be performed: Provides helpful information during the analysis Provides helpful information during the analysis Considerations:Considerations:PartitioningPartitioning HARDWARE PARTITIONING

Identification:Identification: Hardware Partition should include a Numbering or Identification System Uniquely identifies each system, sub-system, etc. Uniquely identifies each system, sub-system, etc. Should identify relationships between parent and child items Should identify relationships between parent and child items Can use existing system or create a new one: Can use existing system or create a new one: CMMS scheme CMMS scheme Equipment Identification Numbers Equipment Identification Numbers Military: WUC, Logistics Control Number, etc. Military: WUC, Logistics Control Number, etc. PartitioningPartitioning HARDWARE PARTITIONING

What level to perform RCM analysis? System or Subsystem level is usually the best starting point System or Subsystem level is usually the best starting point Complexity or other factors may warrant a lower or higher level Complexity or other factors may warrant a lower or higher level Different levels can be used within same analysis Different levels can be used within same analysis Consider on-equipment maintenance level Consider on-equipment maintenance level Level of Analysis: PartitioningPartitioning HARDWARE PARTITIONING

System/Subsystem Analysis: System/Subsystem Analysis: Most efficient for a large scale analysis effort Most efficient for a large scale analysis effort Reduces number of functions to identify Reduces number of functions to identify Secondary functions are easier to identify Secondary functions are easier to identify Aids in proper effects determination Aids in proper effects determination Aids in identification of “significant” failure modes Aids in identification of “significant” failure modes Allows combination of failure modes where it makes sense Allows combination of failure modes where it makes sense Helps focus maintenance tasks on preservation of system/end item operation Helps focus maintenance tasks on preservation of system/end item operation Level of Analysis: PartitioningPartitioning HARDWARE PARTITIONING

Component level analysis: Most effective for limited analysis of a few specific hardware items or failure modes Most effective for limited analysis of a few specific hardware items or failure modes Also useful for analysis of components used on multiple systems Also useful for analysis of components used on multiple systems Level of Analysis: PartitioningPartitioning HARDWARE PARTITIONING

Hardware partition should provide boundary definitions that eliminate confusion over what is/is not included in analysis Examples: Piping or tubing Piping or tubing Controls Controls Air or water supply sources Air or water supply sources Brackets, fixtures, or attach points Brackets, fixtures, or attach points Boundaries/Interfaces:Boundaries/Interfaces:PartitioningPartitioning HARDWARE PARTITIONING
