Abstract
As technology vigorously develops and the awareness of environmental protection rises, green industry has been gradually valued by government and consumers. Customers’ needs can be satisfied with effective resource strategies as well as innovative technology of green products. Importance–performance analysis is a method incorporating the voices of customers and resource strategies of green design into the product development as well as management performance assessment by means of “importance” and “performance.” Quality function deployment can turn the voices of customers into product development and technical requirement, in order to ensure that the product can meet customers’ satisfaction. The present companies take not only customers’ demand but also their own technical limits into account. Hence, data envelopment analysis can offer firms the priority order when they carry out their improvement in the green product design. Nevertheless, many uncertainties and semantic ambiguity appear in the process of information collection for the product design. Consequently, this study comes up with importance–performance analysis, analytical network process, quality function deployment, and data envelopment analysis, to construct an evaluation mode of innovative design for green products based on intuitionistic fuzzy sets offering enterprises a practical reference for their green product design.
Highlights
In recent years, with the rise of environmental protection awareness as well as the concept of sustainable earth, a large number of companies actively use the environmental management as their strategic policy
Many scholars, such as Hun et al.,[30] Li et al.,[31] and Wai et al.,[32] came up with another fuzzy theory combining the above method to deal with the problems of product design; the traditional fuzzy theory still cannot explain ‘‘uncertainty’’ of the human logic thinking, so Atanassov[33] brought up the concept of intuitionistic fuzzy sets (IFS), changing the way of expressing membership by means of numbers resulted from the traditional fuzzy theory into the proportional way of expressions, like ‘‘agree,’’ ‘‘disagree,’’ and ‘‘neutrality.’’ the IFS in the aspect of semantic scale expressions can better meet the mode of human thinking logic and are frequently used in uncertainties or inaccurate information.[34,35,36]
This study applies importance–performance analysis (IPA), analytic network process (ANP), quality function deployment (QFD), and data envelopment analysis (DEA) to construct an IFSbased evaluation mode for green product innovation design, which can effectively control the green innovative required items advantaging enterprises and more accurately transfer customers’ voices into technical requirements; considering the limited resources which enterprises are confronting, we offer references for the prioritization and intensification of the resources required by products’ green innovative technical features
Summary
With the rise of environmental protection awareness as well as the concept of sustainable earth, a large number of companies actively use the environmental management as their strategic policy. Zadeh[29] proposed a fuzzy theory using the mathematical model to describe some fuzzy concepts which cannot be defined, especially the fuzzy characteristics possessed by humans Later, many scholars, such as Hun et al.,[30] Li et al.,[31] and Wai et al.,[32] came up with another fuzzy theory combining the above method to deal with the problems of product design; the traditional fuzzy theory still cannot explain ‘‘uncertainty’’ of the human logic thinking, so Atanassov[33] brought up the concept of intuitionistic fuzzy sets (IFS), changing the way of expressing membership by means of numbers resulted from the traditional fuzzy theory into the proportional way of expressions, like ‘‘agree,’’ ‘‘disagree,’’ and ‘‘neutrality.’’ the IFS in the aspect of semantic scale expressions can better meet the mode of human thinking logic and are frequently used in uncertainties or inaccurate information.[34,35,36]. This study takes the fuel battery as an example explaining the application of this model, in order to offer enterprises a more precise practical evaluation mode for their green product design
