Application

Design takeaway

Implement a modelling approach that maps product functions, behaviours, and structures to anticipate and manage the ripple effects of engineering changes.

How to apply

When planning significant design changes, create an FBS model of the affected product system to trace potential impacts on other components and functions.

Project actions

  • 01When documenting design changes, consider mapping the 'why' and 'how' of the change using a functional or structural breakdown.
  • 02Use diagrams to visually represent the interconnectedness of product components and their functions.

Method & Evidence

AimHow can a Function-Behaviour-Structure (FBS) linkage model be developed and applied to predict and analyze the propagation of engineering changes in complex products?
MethodConceptual modelling and case study analysis
ProcedureA method called FBS Linkage was developed by integrating functional reasoning with change prediction. Products are modelled as networks of functional, behavioural, and structural attributes, with change propagation visualized as spread along these network links. The method was demonstrated with step-by-step techniques and applied to industrial case studies.
ContextProduct development and engineering change management

Variables

IVEngineering change
DVChange propagation impact (e.g., number of affected components, cost, time)
CVProduct complexity, nature of the change, existing product documentation
04

Strengths & Limitations

Strengths

  • +Provides a systematic approach to a complex problem.
  • +Integrates functional reasoning with change prediction.
  • +Validated with industrial case studies.

Limitations

Creating a comprehensive FBS model can be time-consuming and may require deep knowledge of the product's internal workings.

Reliability & validity

The validity of the method relies on the thoroughness of the FBS attribute mapping and the accuracy of the case studies. Reliability would depend on consistent application of the modelling technique by different analysts.

Think critically

How might the complexity of a product's interdependencies influence the effectiveness and feasibility of implementing an FBS Linkage model?

05

Design Principles

"Model product interdependencies to predict and control the impact of modifications."

Understanding how changes ripple through a complex product system is crucial for efficient product development and lifecycle management. This approach provides a structured way to anticipate and mitigate the costly downstream effects of design modifications.

06

What This Means for Your Design

Think of a product like a web of connected parts. If you change one part, this model helps you see how that change will affect all the other connected parts, preventing unexpected problems later.

How to use in your project

  • 1.Use the FBS Linkage concept as a framework to analyze the potential impacts of design decisions or modifications within your design project.

Paragraph starter

The FBS Linkage method provides a valuable framework for analyzing engineering change propagation. By modelling a product's functional, behavioural, and structural attributes as an interconnected network, designers can better predict and manage the downstream effects of design modifications, thereby reducing development costs and time-to-market.
