Ontological Framework

Engineering design is a structured and systematic process of finding solutions to meet certain requirements. Research in this field has focused heavily on developing more effective and efficient product realization process models. Today’s engineering design has become a knowledge intensive and collaborative process, requiring multidisciplinary design knowledge. Therefore, the modeling of knowledge flow plays a key role in determining a successful design alternative, which provides valuable insights into design problems for designers. This article proposes an ontological framework, purpose-function-working space-structure-behavior (PFWSB) for knowledge representation and knowledge flow based design process modeling. An illustrative case is also presented to demonstrate how to use the proposed framework to represent engineering design knowledge and describe the knowledge flow between decision makers during a design process. The results show that this framework can help designers capture the flow of knowledge in engineering design process more effectively.

Abstract Engineering design is a knowledge-intensive process driven by various design objectives. Design is an iterative process where the objectives evolve together with the solutions in order to deliver an artefact with the desired properties and functions. Many design theories developed so far suggest more or less efficient ways for finding a suitable solution to the given goals. However, they often leave open the issue of ‘solution talkback’. Discovery of new design objectives and amendment of the existing ones is as important as the development of design solutions. The biggest issue with solution talkback is the presence of tacit knowledge in addition to the explicit one. This paper draws on a theory that incorporates some typical features of design problems, and transfers theoretical findings about reflection on the design actions to a tool for acquisition of design knowledge. First, key terms are defined and theoretical framework is introduced. Afterwards we look at the means for capturing explicit and tacit design knowledge more in depth.

Abstract: In the 21st century,the domestic economic level has been improved rapidly.At the same time, it has made great progress in the field of building decoration engineering. The building decoration industry has the characteristics of a knowledge-intensive, highly comprehensive and large-scale investment. With the progress of society, architectural decoration design tools have also been with the progress in the building decoration engineering computer-aided design of a wide range of popular applications, change the original product design and production model, the formation of a new architectural decoration engineering design model,which is the biggest change in the decoration industry. For example, the computer technology used in architectural design work, the use of computer technology to collect the corresponding reference materials and computer-aided design to replace the traditional hand-painted and soon. Computer graphics softwarehas the advantages of reasonable layout, easy modification and convenient storage. Thus,computer-aided software is applied in the field of architectural decoration engineering design,which drives the design of building decoration engineering to a higher level. The application of computer aided software can fully reflect its important role in the design of architectural decoration engineering.

AbstractEngineering design reviews, which take place at predetermined phases of the product development process, are fundamental elements for the evaluation and control of engineering activities. These meetings are also acknowledged as unique opportunities for all the parties involved to share information about the product and related engineering processes. For product development teams, the knowledge generated during a design review is not as secondary as it may seem; key design decisions, design experiences, and associated rationale are frequently made explicit. Useful work has been carried out on the design review process itself, but little work has been undertaken about the detailed content of the meeting activity; it is argued that understanding the transactions that take place during a meeting is critical to building an effective knowledge-oriented recording strategy. To this effect, an extensive research program based on case studies in the aerospace engineering domain has been carried out. The work reported in this paper focuses on a set of tools and methods developed to characterize and analyze in depth the transactions observed during a number of case studies. The first methodology developed, the transcript coding scheme, uses an intelligent segmentation of meeting discourse transcriptions. The second approach, which bypasses the time consuming transcribing operation, is based on a meeting capture template developed to enable a meeting observer to record the transactions as the meeting takes place. A third method, the information mapping technique, has also been developed to interpret the case study data in terms of decisions, actions, rationale, and lessons learned, effectively generating qualitative measures of the information lost in the formal records of design reviews. Overall, the results generated by the set of tools presented in this paper have fostered a practical strategy for the knowledge intensive capture of the contents of design reviews. The concluding remarks also discuss possible enhancements to the meeting analysis tools presented in this paper and future work aimed at the development of a computer supported capture software for design reviews.

The term ultimate resolution or resolving power is the very best performance that can be obtained from a scanning electron microscope (SEM) given the optimum instrumental conditions and sample. However, as it relates to SEM users, the conventional definitions of this figure are ambiguous. The numbers quoted for the resolution of an instrument are not only theoretically derived, but are also verified through the direct measurement of images on micrographs. However, the samples commonly used for this purpose are specifically optimized for the measurement of instrument resolution and are most often not typical of the sample used in practical applications.SEM RESOLUTION. Some instruments resolve better than others either due to engineering design or other reasons. There is no definitively accurate definition of how to quantify instrument resolution and its measurement in the SEM.
