An improved IPA approach driven by big data and its application to customer satisfaction research of energy-saving appliance

Against the backdrop of increasing global demand for reducing greenhouse gas emissions, promoting the use of energy-saving and environmentally friendly products has become a crucial aspect of low-carbon economic development. Customer satisfaction plays a vital role in the promotion of these products. To address the challenges of dealing with big data in the conventional customer satisfaction analysis tool, Importance Performance Analysis (IPA), a machine learning-based method is proposed to improve IPA. Firstly, the Latent Dirichlet Allocation (LDA) model is used to capture users’ opinions on different product topics. Then, the Support Vector Machine (SVM) and Random Forest (RF) algorithms are employed respectively to assess the satisfaction and importance of product attributes, enabling an objective measurement of customer satisfaction and adapting to the current trend of big data. The proposed method is applied to the analysis of water heater satisfaction on the JD platform, obtaining satisfaction levels for 10 topics. The research findings demonstrate that the improved IPA method based on SVM-RF effectively explores customer satisfaction and can provide some improvement strategies for platform managers and manufacturers.

Quality and sensory profile evaluation of gluten-free sapodilla-wild almond seed bar with stevia as partial sugar substitution

This research aimed to investigate the quality of fruit bars prepared with different ratios of sapodilla-wild almond seed (80:20 and 70:30 w/w) and sugar substitution with stevia (0, 1/3, and 2/3 as equivalent sweetness basis). Physical properties (moisture and water activity), sensory acceptability, and preference mapping of the fruit bars were investigated. The samples formulated with a higher proportion of sapodilla pulp had higher moisture and water activity than those with less sapodilla pulp. Increasing the sugar substitution with stevia tended to decrease the moisture and water activity of the fruit bars. The stevia incorporation had effects on sensorial attributes, especially the flavor depending on how much sapodilla pulp proportion used in fruit bar preparation. The fruit bars formulated with 80:20 of the sapodilla-wild almond seed and 2/3 sugar substitution and that with 70:30 and full-sugar perceived the highest overall acceptability. The preference mapping revealed the importance of product attributes, and the texture was an important attribute on sensorial acceptance. In conclusion, the fruit bar prepared with 80/20 of sapodilla-wild almond seed and 2/3 sugar substitution with stevia was the most preferred formulation.

Buying a product for an anticipated consumption situation

Purpose – The purpose of this study is to measure the product involvement of wine buyers and to examine relationships with anticipated consumption situations, places and occasions combined with the buyer’s importance of various extrinsic product attributes. Design/methodology/approach – A survey is conducted with 147 wine buyers using structured self-administered questionnaires in a central city retail location in Australia. Findings – There are no significant relationships between consumers’ involvement with wine products and what occasion or constellation of persons is anticipated when purchasing wine in a retail store. From a consumption situation perspective, both high- and low-involved buyers primarily anticipate consuming their wine together with other persons, mainly with food. High-involved wine consumers tend to consume their wine alone compared to low-involved consumers who are more likely to buy wine for other persons than for themselves. Regarding the product attributes that play an important role in retailing, this study finds that the importance of grape variety, the origin of the wine, the brand, the vintage, awards/medals and the product design increases with growing involvement in wine. The age of the buyer/consumer and the envisaged consumption occasion also affect the importance of various product attributes. We also find that wine buyers would spend on average over $15 more per unit when the wine is not bought for their personal consumption (e.g. gift). Originality/value – This study is of value to academic researchers, the wine industry in general and wine retailers in specific as it offers new insights on the role of product involvement and anticipated consumption situations when buying a product and their effects on the importance of product attributes.

선택상황에서의 제품 속성평가를 바탕으로 한 온라인 의류 구매자 세분화

Consumers have more choices for apparel products as e-shopping grows. This study examines the importance of apparel product attributes and classifies online apparel buyers into groups based on product attribute evaluation in various choice sets. For the empirical research, the online survey was conducted and Latent Gold Choice 4.0 was used for the choice-based conjoint analysis. Five consumer segments are found based on the choice selection of product attributes. The importance of product attributes (online shopping mall, brand, price, and style) and the preference of each product attribute level were different across segments. This research improves the knowledge of the purchasing behavior of online apparel buyers and provides proper attribute combinations of apparel e-shopping for each consumer segment.

Importance of Product Attributes in Antihypertensive Product Selection by Physicians

ABSTRACTIn treating hypertension, physicians are often faced with the difficult task of prescribing drugs that provide the greatest benefit with the lowest risks. Physicians treat patients on an individualized. case-by-case basis; however, it is likely that physicians maintain an established procedure for treating their hypertensive patients within the constraints of select patient characteristics and product attributes. The purpose of this study was to supplement understanding of antihypertensive drug prescribing patterns and, using conjoint analysis and direct question ratings, to determine the relative importance of product attributes in physicians' evaluation of a new antihypertensive that is similar to presently marketed products. A 5-page questionnaire was mailed in March 1991 to a national sample of 2.505 physicians that included 835 cardiologists (CARDs). 835 internists (IMs), and 835 family practitioners (FPs). From a total of 630 responses, 562 responses were usable for data analysis. This study...

Food Choice in a Retail Environment

The area of food retailing and consumers′ product preferences is focused on. Valuations in product and price attributes across product categories are investigated. A conceptual framework is developed for analysing food choice situations; product categories and product attributes are identified and measured; the importance of product attributes and the implications for retailers′ marketing mix strategies are assessed. The main conclusion drawn is that for each product category studied (preserves, bakery products, cereals, dairy products, soups, toiletries, fresh meats) customers were looking for different groups of attributes, and different priorities were attached to attributes across product categories.
