Abstract
In order to rationalize material selection in green design, this study presents an attempt to combine the methods of generalized Data Envelopment Analysis (DEA) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). By establishing a green material index system, the G-CCR model of generalized DEA was first used to select effective materials from the candidate samples, and TOPSIS was then used to sort the effective suppliers. The combined DEA/TOPSIS model helps to rank the materials by quality, and then integrate both the merits ofG-CCR model and the key characteristics of TOPSIS. The results of this study showed that the combined DEA/TOPSIS model can screen and exclude materials with poor performance when selecting wood for the furniture industry. Therefore, the combined model that is presented in this study provides a more rational and evidentiary basis for material selection in green design.

The results of this study showed that the combined Data Envelopment Analysis (DEA)/TOPSIS
This study intended to use a DEA method with more extensive methodology that retains all of the properties of the traditional version [46], and it can perform evaluations according to any given reference set, with a generalized DEA (G-DEA)
Summary
Industrial design has modernized our lifestyle and living environment, but it has accelerated the consumption of resources and caused great damage to the world’s ecological balance. “Planned obsolescence” is the extreme manifestation of this This being the case, designers have had to rethink their roles and responsibilities within the industrial sector, and green design has emerged as a consequence of this. Green design is a new trend combining traditional design with the essential relationship between humanity and nature, is guided by ideas of sustainable development and the natural circular economy, and it is aimed at realizing the sustainable utilization of natural resources, the sustainable growth of green wealth, and the constant improvement of both the ecological environment and quality of life. The main idea of green design is to achieve the expected quality level with longer service life and reduced resource consumption [1]. It is sometimes called “design for the future”. This paper focuses on exploring material selection in green design
