“…While divergent thinking is crucial to successful concept generation, convergent thinking is also vital as it determines the direction of the design embodiment stage (Guilford, 1967;King & Sivaloganathan, 1999). Convergent thinking refers to human cognitive activity that seeks a single or best solution through identifying familiar solutions, reapplying set techniques, and accumulating existing information (Cropley, 2006;Guilford, 1967;Runco, 2007;Weisberg, 1999 thinking is necessary to evaluate, synthesize, and select the most promising ideas, and ultimately the concept that will become the final design.…”

Design feedback is an essential pedagogical tool to promote student design progress, yet little research has focused on what instructor feedback looks like, especially across design disciplines. In this paper, we analyzed feedback provided in dance choreography, industrial design, and mechanical engineering to explore variation in feedback type across disciplines as well as how feedback type encouraged students to take convergent or divergent paths in their design processes. Many common feedback types were observed across the three disciplines, regardless of variance in context and expectations, as well as some notable distinctions. With regards to feedback directing convergent and divergent thinking, feedback suggesting convergent pathways was more prominent across all three disciplines. Keywords: design education, design feedback, design processes, conceptual design HIGHLIGHTS• Feedback session settings, approaches and discussions varied by disciplines.• Convergent and divergent feedback were used across diverse design disciplines.• Convergent-directing feedback was more evident across disciplines.Innovative solutions are often traced to ideation, where diverse creative ideas are initiated and developed (Brophy, 2001;Liu, Bligh, & Chakrabarti, 2003). Design processes facilitate this route to bringing ideas to innovative outcomes (Ottosson, 2001;Soosay & Hyland, 2004), and this path toward innovation hinges on successful concept generation, defined as the creation of multiple and diverse concepts (Akin & Lin, 1995;Atman, Chimka, Bursic, & Nachtman, 1999;Liu et al., 2003;Daly, Yilmaz, Christian, Seifert, & Gonzalez, 2012). Students often engage in design ideation during project-based courses such as cornerstone and capstone engineering design courses and domain specific and interdisciplinary studio courses (Dym & Little, 2004;Oh, Ishizaki, Gross, & Do, 2012;Sagun, Demirkan, & Goktepe, 2001;Uluoglu, 2000). Project-based courses often allow for more freedom in timing and pathways, but instructors must make sure students stay on track. Instructor success relies, in part, on the ability to provide guidance and feedback on students' design paths and processes, allowing them to explore on their own, but facilitating a structure where the students can learn strategies to fully explore and define problems, engage in divergent processes by generating a wide range of solutions and converge on and verify the most promising outcomes.In our work, we investigated instructor feedback in dance choreography, industrial design, and mechanical engineering to compare instructors' approaches to guiding students' work. While the content of the design projects was unique to the disciplines, students engaged in design thinking,

서 론첨단Abstract Reliance on road transport in domestic logistics can lead to intensified congestion and greenhouse gas emissions due to the rise in oil prices, any increase in logistics costs can have a high social cost. The government policy on Low Carbon Green Growth is seeking to take advantage of the railway system. However, existing railway transport logistics systems, for reasons such as low speed, low track capacity constraints, and the impossibility of implementing a Door to Door system, make it difficult to activate a railway logistics program. As a result of this study, a national R&D project to develop a High-Speed Passenger/Baggage Mixed Train(Hy-SoBex) utilizing the rail capacity constraints to overcome the difficulties of linking an air cargo and freight railway logistics system, we propose a variety of service models and select the optimal service model.

“…In addition to this, AHP is easier to understand and it can effectively handle both qualitative and quantitative data [2]. However, limitations, such as uncertainty in [18] and inability to provide the information on the compatibility between design concepts in [8], remain as challenges for the concept selection method. To improve the AHP method and to determine the relative weight of criteria for risk assessment, this study proposes a structure conceptual design selection model based on the use of fuzzy analytic hierarchy process (FAHP) and triangular fuzzy numbers.…”

Abstract-Selecting a design at the conceptual design stage in product development can be complex and frustrating due to imprecise and uncertain product requirements. For many companies, the conceptual design stage is crucial to their product's success. For example, making a bad decision can lead to costs associated with product recall, redesign, and remanufacture. These unexpected expenses not only could result in profit loss but also jeopardize a successful commercialization of the product. Therefore, the level of success of a product is significantly dependent on the early stage of product development. Managers need robust decision-making tools for valuing potential new product investments in order to justify their development strategy and to allow them to screen out new designs that stand little chance of success at an early stage. However, limitations, such as uncertainty and inability to provide the information on the compatibility between design concepts, remain as challenges for the concept selection method. Therefore, this study proposes a structured conceptual design selection model based on fuzzy analytic hierarchy process (FAHP) and fuzzy conflict resolution to express the comparative judgments of decision-makers. Also, we perform a comparative analysis between AHP and FAHP results by applying our model to hospital bed designs. This study proves that although both methods are good, FAHP is more robust because of eliminating inconsistencies resulted from personal feelings or judgments.Index Terms-Conceptual design stage, AHP, fuzzy AHP, ergonomic design, design for reliability, conflict resolution.
