This study began from the idea that new materials and awareness in the modern society demand new methods in architecture and focused on diagrams as the tool many modern architects use in their process of architectural design. Therefore, the purpose is re-finding the potential of diagrams as profilerating architectural design media by examining mentions of architects about diagrams, investigating diagrams used in design process and treating comments referring to diagrams, by redefining the meaning of the contemporary architecture and of diagrams in architecture, and by grasping the various methods of use and its process. The design process using diagrams produces synthetic or reasonable process dissimilar to previous processes. Where diagrams are mainly used as tools to relate the segregated parts compressively. On the other hand reasonable process concerns reasonable design advancement to satisfy various requirements or conditions in reality, where diagrams are used as tools offering its phase in the whole structure of various information and relating steps of design each other. Dealing synthetically in the various steps of design process with the various properties originally obtained, proposing a new type of architecture by increasing thoughts and leaving the design process open-fluid, offering process and results having the same value as design process, and satisfying requirements in reality most reasonably, diagrams working in the above-mentioned design process have the potential to narrow the schism among theory, practice and criticism in contemporary architecture.

Capstone design education is essential in the engineering design process according to the certification standards of ABEEK. Capstone design process should be properly trained in undergraduate courses in order to increase the design ability of systems, components and processes within realistic constraints. In this study, a modified design model as a capstone design education model was proposed to reduce the separation between the design process at industrial sites and the design process at university education. The modified design model based on 6-sigma methodology is composed of 6 design steps such as define, measure, analyse, design, verify, and report. Each step has appropriated design contents and tools, and is configured to generate design results. The proposed design model was directly applied to the capstone design class for automotive engineering in Kunsan National University, and it was confirmed that the proposed DMADVR methodology was a very useful design education model to enhance the design ability, teamwork ability and communication skills required by ABEEK.

This study investigated the key role of sketches in creative fashion design by observing the cognitive process of idea development through a professional's design problem solving using the medium of hand sketching. The three-part semi-constrained design experiment with a professional designer, in which the participant designer was provided a source of inspiration image and asked to design a small collection of outfits, identified a fashion designer's idea development process as involving two phases of sketch processes: lateral and vertical transformation. Analysis of the video/audio recording and corresponding interviews validated lateral transformation in the designer's use of sketches to represent interpretation of the provided inspiration source. Through sketching, the designer transferred fuzzy ideas onto paper. Vertical transformation was observed through the designer's modification of previous ideas after reflecting on earlier sketches, with various ideas divided, manipulated, discarded, regrouped, and combined through sketching activities. The designer's sketching process is valuable design knowledge that facilitates the idea development process and ultimately triggers generation of creative ideas. Understanding it may benefit practitioners and educators.

To efficiently design safety-critical systems such as nuclear power plants, with the requirement of high reliability, methodologies allowing for rigorous interactions between the synthesis and analysis processes have been proposed. This paper attempts to develop a reliability-centered design framework through an interactive process between Axiomatic Design (AD) and Fault Tree Analysis (FTA). Integrating AD and FTA into a single framework appears to be a viable solution, as they compliment each other with their unique advantages. AD provides a systematic synthesis tool while FTA is commonly used as a safety analysis tool. These methodologies build a design process that is less subjective, and they enable designers to develop insights that lead to solutions with improved reliability. Due to the nature of the two methodologies, the information involved in each process is complementary: a success tree versus a fault tree. Thus, at each step a system using AD is synthesized, and its reliability is then quantified using the FT derived from the AD synthesis process. The converted FT provides an opportunity to examine the completeness of the outcome from the synthesis process. This study presents an example of the design of a Containment Heat Removal System (CHRS). A case study illustrates the process of designing the CHRS with an interactive design framework focusing on the conversion of the AD process to FTA.

There are so many theories and arguments on the architectural design process. However, in the time of the environmental preservation, there is the need for the introduction of the systematic green design process because no existing design process theories could give the rational design tool far the integrated design with environmental factors. This study, through the literature survey, is on the new paradigm for the systematic approach to the integrated process of 'the Green Design'.

This paper describes a step-by-step method to minimize design iterations in a process of product design change. In the design process, two components are coupled if a change of a component can require the other components change, and design iterations are generated by the coupling. The design iteration is one of main factors that increase design effort. In this study, three matrices are used to solve the design iteration of automatic transmission lever, Requirement-Engineering matrix, Engineering-Components matrix, and DSM(Design Structure Matrix). Firstly, with the DSM, the product architecture and conceptual design process are proposed from product function analysis. Secondly, with the QFD, the Requirement-Engineering matrix and Engineering-Components matrix present the relationship among customer requirements, engineering issues, and product components. Lastly, the results of the QFD analysis are used in the DSM to solve the component interactions and to provide design

This paper describes an approach to collaborative design which focuses on the effects of individual activities on the overall design process. We utilize a new process modeling tool to define the process and then analyze and refine the process based on critical paths. This information is then shared over the Internet with all participants. The goal of this system is to detect critical errors at initial design stage and guide the designers to make better decisions based on the knowledge of the overall process. This system enables participating designers to publish his local process through an Internet bulletin board. Other members of the team can then provide feedback based on how the proposed process impacts their activities. The system provides a context-rich, persistent forum for collecting, preserving, and refining corporate expertise of the team. For example, designers can select any process from the bulletin board and use it as a template for his current project and then use it to maintain his own design history. This paper is based on the process modeling concepts of Design Roadamap and describe several key extensions in the area of CPM calculations and collaborative interfaces.

The purpose of this paper is to find the preconditions of BIM based new design process. As BIM technology improves, investigating new design process will become a greater priority. Our traditional, linear and fragmented design process is not freed from a long-pending questions of poorly coordinated drawings and low production efficiencies. Rather the traditional process is one of the major causes of such issues of low productivity. AIA and NIST proposed new design process to fulfill clients' need for fast and precise delivery recently. The common goal of these two should be better, faster and more precise project delivery created by integration. And we need to create collaborative concurrent design process to optimize the design efforts, But our local AE industry's circumstances are quite different with foreign countries. Therefore, integrated project system cannot be adopted as it stands in foreign countries. This paper will investigate preconditions to expedite the progress of BIM based design process in Korea.

Design goal is to find the one that has the highest probability of success and the smallest variation. A robustness index has been proposed to satisfy these conditions. The two-step optimization process of the target problem requires a scaling factor. The search process of a scaling factor is replaced with the making of the decoupled design between the mean and the standard deviation. The decoupled design matrix is formed from the sensitivity or the sum of squares. After establishing the design matrix, the robust design process has a new three-step one. The first is ″reduce variability,″ the second is ″make the candidate designs that satisfy constraints and move the mean on the target,″ and the final is ″select the best robust design using the proposed robustness index.″ The robust design process is verified by three examples and the results using the robustness index are compared with those of other indices.

Fractures and wrinkles are two major defects frequently found in the sheet metal forming process. The process has several noise factors that cannot be ignored when determining the optimal process conditions. Therefore, without any countermeasures against noise, attempts to reduce defects through optimal design methods have often led to failure. In this study, a new and robust design methodology that can reduce the possibility of formation of fractures and wrinkles is presented using decision-making theory. A two-attribute value function is presented to form the design metric for the sheet metal forming process. A modified complex method is adopted to isolate the optimal robust design variables. One of the major limitations of the traditional robust design methodology, which is based on an orthogonal array experiment, is that the values of the optimal design variables have to coincide with one of the experimental levels. As this restriction is eliminated in the complex method, a better solution can be expected. The procedure of the proposed method is illustrated through a robust design of the sheet metal forming process of a side member of an automobile body.
