Understand the Equipment Structure

Learn to distinguish functional systems from parent–child equipment relationships and interpret an existing equipment structure in the ManWinWin App.

A well-defined equipment structure is fundamental for efficient maintenance management, providing clarity on how assets relate functionally and physically. Understanding this organization in ManWinWin App ensures you can accurately track, manage, and optimize maintenance tasks for each asset.

Where it's available and step by step

Step by step in ManWinWin App

1
In the ManWinWin App, open Others > Objects to access the equipment list.
2
Navigate through the systems structure and choose an existing system whose function you recognise.
3
Open an object in that system and consult its system information to identify its functional grouping.
4
Consult the parent object information to determine whether the selected equipment belongs under another asset.
5
Return to the objects list, locate the identified parent object and open its details to compare its system and parent information with those of the first object.
6
Trace the relationship you have inspected, distinguishing the system’s shared function from the parent–child equipment relationship, without editing either record.

Theory and technical background

The Importance of Equipment Hierarchy

Equipment hierarchy, also known as asset hierarchy or structure, organizes physical assets based on their relationships. This structure can reflect physical connections (e.g., a motor within a pump) or functional groupings (e.g., all components of a production line). A logical hierarchy is crucial for planning maintenance, allocating resources, and tracking costs accurately. It enables a clear understanding of how the failure of one component might affect others, supporting criticality assessments and streamlined work order management. ISO 14224 emphasizes consistent classification and structuring of technical systems for reliability data collection.

Functional Systems vs. Parent-Child Relationships

It's vital to distinguish between functional systems and parent-child physical relationships. A functional system groups assets that collectively perform a specific function, regardless of their physical location or direct connection (e.g., all equipment related to 'HVAC System A'). Parent-child relationships, conversely, define a physical breakdown where a 'child' component is part of a 'parent' assembly (e.g., a 'Motor' is a child of a 'Pump'). Both are essential for a comprehensive CMMS, offering different perspectives for maintenance planning, fault isolation, and cost analysis. Clear definitions prevent confusion and improve data integrity.

Benefits for Maintenance and Operations

An accurately represented equipment structure in your CMMS significantly enhances maintenance and operational efficiency. It simplifies locating assets, assigning work orders to the correct equipment, and analyzing failure patterns at various levels. For instance, you can calculate MTBF (Mean Time Between Failures) not just for individual assets but also for entire systems, providing insights into overall reliability. This structured approach supports effective spare parts management by linking parts directly to the relevant equipment, reducing search times and inventory errors. Ultimately, it optimizes resource allocation and contributes to higher asset availability and OEE (Overall Equipment Effectiveness).

Best practices

Always verify both functional system and parent-child data when inspecting an asset.
Use descriptive naming conventions for systems and equipment to improve clarity.
Regularly review your equipment structure for accuracy, especially after asset changes.
Understand that a single asset can belong to multiple functional systems (e.g., safety, electrical).

Frequently asked questions

Why is an accurate equipment structure important in ManWinWin?

An accurate structure is vital for precise maintenance planning, cost tracking, and efficient work order management. It helps in understanding asset relationships, streamlining operations, and improving data analysis for better decision-making.

What is the difference between a functional system and a parent-child relationship?

A functional system groups assets by their shared operational purpose, while a parent-child relationship describes a physical component hierarchy (e.g., a pump within a larger assembly). Both are crucial for comprehensive asset overview.

Can equipment belong to more than one functional system?

Yes, an asset can be part of multiple functional systems. For example, a motor might be part of a 'Production Line System' and also a 'Safety Interlock System', depending on its roles.
