This qualitative study explores the impact of online food delivery platform attributes on customer satisfaction and repurchase intentions. Employing a phenomenological approach, we conducted in-depth interviews and focus group discussions with 15 participants to gain rich insights into user experiences. Thematic analysis revealed key factors influencing satisfaction and loyalty: service quality dimensions (efficiency, reliability, fulfillment, privacy), expectation disconfirmation, perceived usefulness and ease of use, multi-level customer value, relationship quality, electronic word-of-mouth, value co-creation, and phased loyalty formation. Our findings extend customer behavior theory in digital platforms, offering a comprehensive framework for understanding the complex mechanisms underlying user satisfaction and repurchase decisions. The study provides valuable implications for platform operators, highlighting the importance of exceeding customer expectations, enhancing user experience, building trust, leveraging user-generated content, and fostering co-creation processes. Methodologically, we demonstrate the efficacy of qualitative approaches in uncovering nuanced insights in digital service contexts. While acknowledging limitations in generalizability, this research establishes a solid foundation for future investigations into the rapidly evolving domain of online food delivery services. The integrated theoretical approach offers a robust model for analyzing customer behavior in emerging digital service environments, contributing significantly to both academic understanding and practical application in the field of digital service provision and platform management.

In this paper, a versatile multi-criteria optimization concept for fatigue life prediction is introduced. Multi-criteria decision making in engineering design refers to obtaining a preferred optimal solution in the context of conflicting design objectives. Compromise decision support problems are used to model engineering decisions involving multiple trade-offs. These methods typically rely on a summation of weighted attributes to accomplish trade-offs among competing objectives. This paper gives an interpretation of the decision parameters as governing both the relative importance of the attributes and the degree of compensation between them. The approach utilizes a response surface model, the compromise decision support problem, which is a multi-objective formulation based on goal programming. Examples illustrate the concepts and demonstrate their applicability.

To enrich a country's food culture, it is essential that residents understand and care about that culture. Although various efforts to globalize Korean food have been made outside Korea, the importance of understanding Koreans' perception of and increasing interest in Korean food has been neglected. Thus, this study was conducted to identify the cognitive structures regarding Korean food among 30 Koreans living in metropolitan cities using in-depth laddering interviews based on the means-end chain theory. The most dominant cognitive structures toward Korean food were familiarity (attributes), ease of digestion and health (functional consequences), sense of responsibility and will to live (psychosocial consequences), and family affection and sense of achievement (values). In short, Koreans were found to consume Korean food to achieve perceived high-dimensional values rather than simply for its attributes or benefits. These findings have important implications for future strategies and policies aimed at increasing Korean food consumption by Koreans, as they suggest that underlying and symbolic values rather than the attributes of Korean food are more effective in promoting its consumption. Further studies on understanding perceptions and values using a larger Korean population are needed to preserve and further develop Korean food.
