An enhanced multidimensional requirement oriented quality function deployment method for sustainable self service...

Area of Science:

• Engineering
• Environmental Science
• Product Design

Background:

• Self-service machines offer efficiency but lack sustainability focus in design.
• Growing environmental concerns necessitate integrating sustainability into product development.
• Existing methods often neglect the multidimensional nature of sustainability requirements.

Purpose of the Study:

• To propose an enhanced multidimensional requirement-oriented quality function deployment (QFD) method.
• To address the gap in current sustainable product design approaches.
• To facilitate the development of sustainable self-service machines.

Main Methods:

• Utilizing multiple one-dimensional quality of houses within an enhanced QFD framework.
• Independently processing requirements across different sustainability dimensions.
• Reducing complexity compared to traditional QFD methods.

Main Results:

• The proposed method enables a more comprehensive and strategically aligned design process.
• It effectively prioritizes key sustainability dimensions in product development.
• Demonstrates a robust framework for developing sustainable self-service machines.

Conclusions:

• Embedding sustainability into self-service machine design is crucial for resource efficiency and environmental protection.
• The enhanced multidimensional QFD method provides a balanced approach to sustainability.
• This framework aligns design outcomes with critical sustainability goals.
