A methodology incorporating functional simulation can effectively manage design uncertainties in the early stages of product development.
University of Canterbury Research Repository (University of Canterbury) · 2001
Key Findings
- 01Existing design methodologies are often unsuitable for early design stages due to information incompleteness.
- 02A methodology that simulates system behavior using both quantitative and qualitative data can support designers amidst high uncertainty.
- 03The DSI methodology, when embodied in software, can provide multiple viewpoints (e.g., performance, cost, reliability) on a design.
- 04The DSI methodology successfully simulated wash performance in a probabilistic manner for a dishwasher case study.
Application
Design takeaway
Integrate functional simulation tools into your early-stage design process that can accommodate both precise data and qualitative estimations to better manage inherent uncertainties and explore design trade-offs.
How to apply
When starting a new design project, consider using simulation software that allows for the input of uncertain parameters and can model system behavior to predict potential outcomes across various scenarios.
Project actions
- 01When exploring initial concepts, consider how you might simulate their basic functions, even with incomplete data.
- 02Think about how software can help you manage the uncertainties in your design choices.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Addresses a critical gap in design methodologies for early stages.
- +Proposes a concrete methodology (DSI) and its software implementation.
- +Demonstrates application through a case study.
Limitations
The computational intensity of advanced simulation can be a barrier. Early-stage simulations will inherently be less accurate than those performed with complete data.
Reliability & validity
Reliability would depend on the consistency of the simulation algorithms and the user's input. Validity would be assessed by comparing simulation predictions against later, more detailed analyses or actual prototype performance.
Think critically
To what extent can qualitative data truly inform quantitative simulations in early-stage design, and what are the risks of over-reliance on such estimations?
Design Principles
"Employ functional simulation with uncertainty management capabilities to de-risk early-stage design decisions."
Traditional design methods often falter when faced with the inherent ambiguity of initial concept development. This research highlights the value of simulation-based approaches that can integrate both quantitative and qualitative data, providing crucial insights even with incomplete information.
What This Means for Your Design
When you're just starting to design something, it's hard because you don't have all the answers. This research shows that using computer simulations that can guess or use rough information can help you figure out how your design might work and what problems it might have, even before you have all the exact details.
How to use in your project
- 1.Reference this study when discussing the challenges of early-stage design and how simulation can be used to overcome them.
- 2.Use the concept of functional simulation to justify your own early-stage modelling choices.

Paragraph starter
The challenges of uncertainty in early design stages are well-documented, with research such as Pons (2001) proposing functional simulation as a key methodology. This approach allows for the modelling of system behaviour using both quantitative and qualitative data, thereby providing valuable insights and supporting decision-making even when complete information is unavailable.
