Evidence
Strong effect

A multi-criteria decision model can predict vehicle variants that satisfy both customer quality expectations and minimize life cycle environmental impact. This sustainability research insight is drawn from a 2023 study published in Energies. Using Multi-criteria decision making (mcdm) incorporating life cycle assessment (lca), topsis, smarter, pareto-lorenz, and the 7±2 rule., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate quantitative life cycle assessment alongside user-centric quality metrics early in the design process to identify optimal, sustainable product variants.

Application

Design takeaway

Integrate quantitative life cycle assessment alongside user-centric quality metrics early in the design process to identify optimal, sustainable product variants.

How to apply

When designing new products, especially in sectors with significant environmental impact like transportation, use a multi-criteria decision framework that includes both user-perceived quality and life cycle environmental performance.

Project actions

  • 01When evaluating design options, consider using a scoring system that accounts for multiple factors.
  • 02Research and incorporate Life Cycle Assessment (LCA) data to understand the environmental impact of materials and manufacturing processes.

Method & Evidence

AimTo develop a model that supports the prediction of vehicle variants that are satisfactory to the customer in terms of quality level and environmental impact throughout their life cycle.
MethodMulti-Criteria Decision Making (MCDM) incorporating Life Cycle Assessment (LCA), TOPSIS, SMARTER, Pareto-Lorenz, and the 7±2 rule.
ProcedureA model was developed and tested using production variants of battery electric vehicles (BEVs). Quality levels and life cycle assessment scores were estimated and weighted to determine overall vehicle satisfaction and environmental friendliness.
ContextAutomotive design and manufacturing, specifically focusing on electric vehicles.

Strengths & Limitations

Strengths

  • +Integrates multiple established decision-making and assessment methodologies.
  • +Provides a quantitative framework for evaluating complex design trade-offs.
  • +Focuses on a critical area of sustainable product development.

Limitations

The accuracy of your evaluation depends heavily on the quality and availability of data for both user preference and environmental impact.

Reliability & validity

The reliability of the model depends on the consistency of the LCA data and quality assessment methods used. Validity is supported by the use of established MCDM techniques and their application to a real-world product type (BEVs).

Think critically

How might the weighting of 'quality level' versus 'environmental impact' change depending on the target market or regulatory environment?

05

Design Principles

"Sustainable design decisions should be informed by a balanced consideration of user needs and comprehensive environmental impact analysis."

This approach allows designers and manufacturers to proactively integrate sustainability into the product development process. By considering both user satisfaction and ecological footprint early on, design teams can make informed decisions that lead to more desirable and responsible products.

06

What This Means for Your Design

You can figure out the best car design by looking at how good it is for the user and how good it is for the planet over its whole life. This helps make cars people like and that are also eco-friendly.

How to use in your project

  • 1.Reference this study when discussing the importance of balancing user needs with environmental considerations in your design project.
  • 2.Use the methodology as inspiration for developing your own evaluation criteria for design solutions.

Paragraph starter

This research highlights the critical need to integrate comprehensive Life Cycle Assessment (LCA) with user-centric quality metrics during the design phase. By employing multi-criteria decision-making models, as demonstrated in the study by Ulewicz et al. (2023), designers can systematically predict and develop product variants that optimally balance customer satisfaction with environmental responsibility throughout the entire product lifecycle, thereby informing more sustainable design strategies.
