Abstract In this paper, different iterative methods, so-called architectures, within the multidisciplinary analysis in conceptual aircraft design of UNICADO software are elaborated, applied and analyzed. Possible execution sequences sequential method (Gauss-Seidel architecture) derived via a graph-based algorithm combination with expert knowledge. Sensitivities disciplines analyzed permitted re...

This Conceptual Design Report describes LUXE (Laser Und XFEL Experiment), an experimental campaign that aims to combine the high-quality and high-energy electron beam of European with a powerful laser explore uncharted terrain quantum electrodynamics characterised by both high energy intensity. We will reach this hitherto inaccessible regime physics analysing electron-photon photon-photon inter...

Historical archived satellite images were compared with contemporary satellite data to track ongoing changes in more than 10,000 large lakes in rapidly warming Siberia. A widespread decline in lake abundance and area has occurred since 1973, despite slight precipitation increases to the region. The spatial pattern of lake disappearance suggests (i) that thaw and "breaching" of permafrost is dri...

Innovation design for complex products is a difficult issue in the military manufacturing industry. Ontology may provide a feasible way to rebuild the design process for complex products via sharing and reusing of design knowledge. In this paper, a design method used in the innovation design process of the complex products with knowledge modeling is proposed. Knowledge modeling is realized thro...

Systems of Systems (SoS) are a current focus of many organizations interested in integrating assets and utilizing new technology to create multi-component systems that deliver value over time. The dynamic composition of SoS along with the managerial independence of their component systems necessitates systems engineering considerations and methods beyond those of traditional systems engineering...

Information modeling is critical to the integration of conceptual design and process planning. An information model for conceptual design is provided in this paper. Conceptual design is a key activity in early product development. It determines product functions, form, and the basic structure. Major manufacturing cost is committed in early conceptual design process. The model presented in this ...

Although many attempts have been made in presenting systematic models for design processes, most projects have been implemented by non-systematic methods, which seems that too much emphasis on the description of the final project (product) and the lack of attention to the design process are to be blamed for this. In this paper, a specific pattern of design scenario formation in the framework of...
