Abstract
In the current era of economic and cultural globalization, the demand for packaging design is increasing, and the packaging design requirements for brands and products in the entire consumer market are becoming increasingly strict and refined. Designers are facing one greater challenge after another. Packaging design, as a comprehensive discipline that integrates commerce, culture, and art, diverse cultural forms and elements will run through the entire process of brand packaging design. Good products need to be sold through good channels in order to achieve greater value. As a bridge connecting products and the market, the role of packaging design is even more evident. It can not only improve the recognition of products, but also help enterprises stand out among many similar products, thereby increasing product value. The brand packaging design effect evaluation is a classical multiple attribute group decision making (MAGDM) problem. This paper extends the EDAS method to the 2-tuple linguistic Pythagorean fuzzy sets (2TLPFSs). On the basis of the original EDAS method, 2-tuple linguistic Pythagorean fuzzy EDAS (2TLPF-EDAS) method is built for MAGDM. Finally, a case study for brand packaging design effect evaluation show that the new method proposed in this paper is reasonable.

Introduction
Decision making is a process of action from a multitude of alternatives. Multi attribute decision-making (MADM), also known as finite scheme multi-objective decision-making, refers to the decision-making problem of selecting the optimal alternative solution or ranking solutions considering multiple attributes [1–3]. It is an important component of modern decision-making science. Its theory and methods are widely applied in many fields such as engineering, technology, economy, management, and military. Then, Atanassov [4] defined the intuitionistic fuzzy sets(IFSs). Yager [5] defined Pythagorean fuzzy sets (PHFSs). Then, the methods related to the MAGDM have been fully applied to PHFSs, for example, EDAS method [6–8], PRETHEE method [9], GRA method [10], MULTIMOORA method [11]. Furthermore, Deng et al. [12] proposed the 2-tuple linguistic Pythagorean fuzzy sets (2TLPFSs) based on Hamy Mean operators [13–18]. Deng et al. [19] proposed the weighted BM (WBM) operator, generalized WBM (GWBM) operator and dual GWBM operator under 2TLPFSs based on the classical BM operator [20–25]. Deng and Gao [26] proposed the TODIM method under 2TLPFSs for MADM. He et al. [27] proposed the CODAS method under 2TLPFSs for MAGDM. Deng et al. [28] proposed some Muirhead Mean (MM) operators [29–36] under 2TLPFSs.
Whether it is packaging design or brand image, the ultimate attraction is always consumers. To shape a successful brand image, it is necessary to achieve a transformation from quantity to quality. The success of a brand comes from the decisions of consumers or service recipients. The formation of a brand is achieved through continuous innovation in stable development [37, 38]. At a certain stage, it is necessary to obtain innovative and functional packaging design based on the original basic functions of the packaging [39, 40]. This has gradually become an important tool for shaping a good brand image, and is an important part of establishing a good and deeply rooted brand image and identity. Package design is an important channel that connects brands and end users [41, 42]. It is not only the main sales method for enterprise products, but also the necessary support for establishing a unified visual image of the brand through good packaging design, reflecting the standard colors, text, graphics, and other characteristics of the enterprise. Promoting a unified visual image of enterprise products is beneficial for distinguishing between brands, enabling consumers to have a deeper understanding of the brand and corporate image, and to a certain extent, to have a sense of identity [43, 44]. This promotes enterprises to highlight their own characteristics in competitive products, and forms scale on this basis. Secondly, packaging design has its own unique expression form and contains unique creative concepts, which can effectively strengthen the brand personality of the product and provide support for the brand to achieve accurate market positioning. A successful packaging design should not only have a visually appealing appearance, but also have a memorable brand impression for consumers [45, 46]. The meaning of the images on the packaging and the brand name need to complement each other, and the uniqueness of packaging design can effectively provide an important foundation for the success of brand personality highlighting. Brands can still be recognized and representative by society to form a culture, which requires recognizing that the visual image of every successful product brand always relies on the characteristics of creative overall packaging visual design [47, 48]. While strengthening the strength of brand personality cultivation, it meets the needs of brand image shaping, making the brand image deeply rooted in people’s hearts. Once again, packaging design deepens the brand image into people’s hearts. As people’s living standards continue to improve, the requirements for natural quality also need to be significantly elevated [49, 50]. Therefore, packaging design plays an important role in the development process of homogenization of this product. In different uses and grades, and when observing different objects, it is also necessary to strengthen the serialization and matching design of packaging design, provide support to avoid being eliminated by brands in the same industry [51, 52]. Finally, with the global warming and frequent occurrence of natural disasters, China needs to fully reflect the characteristics of green packaging design when carrying out brand design, helping people realize the importance of protecting nature and coexisting harmoniously with nature. This has also become a successful brand trend with directional characteristics. On this basis, in order to be able to design a more mature corporate brand, it is necessary to permeate the meaning and values of brand culture into different aspects of company behavior, which are usually reflected in corporate responsibility and the moral and ethical values it represents. In the information society, the development of high-tech has a greater impact on the current market order. The load capacity of the natural environment is constantly increasing, and environmental protection is also an important issue of global concern [38, 53]. The important role of packaging design in shaping the visual brand image of enterprises has also received attention and attention. During this period, brand images with new environmental concepts will also be widely concerned by consumers, Enterprises should also actively face new challenges in packaging design, lay an important foundation for brand building, gain consumer favor, attract consumer attention, effectively enhance market competitiveness, and enable sustainable development of the enterprise [37, 54]. In short, on the basis of ensuring the effectiveness of visual brand image, it is necessary to deeply highlight the role of brand packaging design. In packaging design, design works that have more brand characteristics to ensure that the brand image is more deeply rooted in people’s hearts [55, 56].
The brand packaging design effect evaluation is a classical MAGDM problem. This paper extends the EDAS method to the 2TLPFSs. On the basis of the classical EDAS method [6], 2-tuple linguistic Pythagorean fuzzy EDAS (2TLPF-EDAS) method is proposed for MAGDM. Finally, a case study for brand packaging design effect evaluation show that the new method proposed in this paper is reasonable. In order to realize the research purpose, the research framework of this paper is given. In the Sect. 2, we introduce the 2TLPFSs. In the Sect. 3, the new 2TLPF-EDAS method in built for MAGDM. In the Sect. 4, by a numerical case about brand packaging design effect evaluation is given. In Sect. 5, we get some conclusion.

Appropriate product packaging design can effectively enhance product display opportunities, increase product sales, and bring more economic benefits to enterprises. It is precisely because of this that businesses are currently paying more attention to product packaging design. But is your product packaging design effective? In order to achieve a more significant effect in packaging design, the following principles should be followed: (1) The simple and concise packaging design style has been popular for many years, and it is still very popular in the packaging market today. Simple packaging design can better convey important information about products, allowing consumers to easily find the products they need through product design among numerous products. If the packaging design content of a product is too complex, consumers may have looked at it for a long time without knowing what the packaging design is intended to convey, and they are likely to give up choosing the product. (2) When designing product packaging, it is important to pay attention to the selection of colors, as those with low saturation will give people a sincere and warm feeling, and visually give consumers a pleasant impression. Therefore, in packaging design, it is necessary to avoid using overly bright colors. (3) The main purpose of packaging products with movie posters is to make them stand out among similar products. You can try designing product packaging in the form of movie posters, which is also a way to attract consumers’ attention. The form of movie posters can effectively highlight the theme of the product and convey the main information of the product to consumers. (4) Is the core message you want to convey highlighted in large font in your packaging design? It should be noted that the large font on the packaging can effectively attract consumers’ attention and allow them to see the characteristics of the product in the first place. So the important information in packaging design can be bolded or paired with different colors, and I believe your product will stand out among similar products. (5) When designing packaging for products, it is best to choose a creative design. For example, if we want to package a certain food, we can place the food in a tree hole or fruit juice in a bamboo joint on the packaging. This is a very correct design, and the unique packaging design will become a major selling point of the product. The brand packaging design effect evaluation is a MAGDM. In this section, we provide a numerical example for brand packaging design effect evaluation by using 2TLPF-EDAS method. Assume that five possible brand packaging design schemes PA
i
(i = 1, 2, 3, 4, 5) to be selected and four attributes PO
j
(j = 1, 2, 3, 4) to assess the brand packaging design schemes: PO1 conveys the visual attraction effect. Visual attraction effect refers to the effect of packaging on attracting customers’ attention. As long as customers notice the existence of the product, they can further observe the product and make purchasing decisions based on the information obtained. Visual attractiveness is the primary condition for evaluating packaging design. Only with good attractiveness can a product stand out on the shelf, achieve further sales goals, and convey brand information. PO2 conveys the information communication effect. The information conveyed in packaging design can generally be divided into two types. One type is to clarify information, such as practical information such as product quantity, specifications, and application explanations. This type of information is mainly used to help users use the product correctly. The second type is promotional information, such as product features, advertising slogans, brand positioning, and so on. The function of this type of information is the function of shopping malls, such as stimulating users to purchase, strengthening brand information, etc. The information on a good packaging should be graded, meaning there are differences in importance. PO3 conveys the artistic and aesthetic effects. Artistic and aesthetic effects refer to the appearance of packaging that should bring visual pleasure to users and have a certain aesthetic feeling. In some packaging plans, visual elements such as text, graphics, and logos are often inappropriately highlighted in order to emphasize promotion or brand information. Perhaps all product information that can be placed is piled up on the packaging, leading to a decrease in packaging quality and leaving users with a vulgar and cheap image. PO4 conveys the functional effect. The functional effect mainly refers to the examination of the practical function of packaging. The most basic function of product packaging is to protect and use the product. In general, packaging should meet the following application functions, including product protection, easy transportation and storage, convenient carrying and use, safety, and environmental protection.
The brand packaging design effect evaluation is depicted with 2TLPFSs by DMs by using four attributes PO j (j = 1, 2, 3, 4), The five brand packaging design schemes PA i (i = 1, 2, 3, 4, 5) will be evaluated with 2TLPFSs with the four criteria by three experts PD t (t = 1, 2, 3) (Suppose expert’s weight is (0.27, 0.34, 0.39).

Packaging design, as a carrier of culture, inherits the national cultural spirit and regional cultural characteristics of a country or region, such as social ideology, aesthetic tendencies, moral ethics, folk customs, etc. The physical expression of packaging that integrates regional culture can appeal to people’s visual senses through its direct and artistic image. It can effectively guide consumer choices, enhance consumer taste, promote product sales, and achieve the shaping, development, and dissemination of brand image. Brand image is the individual characteristics of a brand in the market and the public, reflecting the public’s understanding and evaluation of the brand, reflecting the essence and strength of the brand. It includes three parts: brand concept, brand behavior, and brand vision. Among them, brand concept lays the central framework of the overall brand image, brand behavior reflects the dynamic process of the brand, and brand vision displays the brand image through material media such as products, packaging, advertising, and directly connects with the public. The brand packaging design effect evaluation is a MAGDM problem.This paper extends the EDAS method to the 2TLPFSs. On the basis of the original EDAS method, the 2TLPF-EDAS is built for MAGDM. Finally, a case study for brand packaging design effect evaluation is given and some comparative analysis with the other methods show that the new method proposed in this paper is effective and accurate.
