Using concurrent design methodology, the duration of space science mission in conceptual design phase can be shortened. This approach requires hardware and software resources to support, such as professional design tools and concurrent design environment. Except for the professional groups, the general researchers such as teachers and students have no chance to access these resources. Nowadays, more and more researchers distributed in different locations join into the space science research. The need for an open concurrent design platform offering design tools and data sharing environment has increased. This article presents a Cloud Platform of Concurrent Design for Space Science Mission. This Cloud Platform of Concurrent Design for Space Science Mission uses the idea of Software as a service, in which five design and analysis tools are offered as services to satisfy the basic requirements for space science mission concurrent design in conceptual design phase. This cloud platform provides the access to space science mission concurrent design for expert and non-expert users using a thin client of web browser. This article presents the platform architecture of the Cloud Platform of Concurrent Design for Space Science Mission and five software offered as services. The services include spacecraft conceptual orbit design, structure design, payload coverage analysis, data transmission analysis, and virtual community. And the basic cloud service (computing and storage) is also briefly introduced. It is described in detail how these services can be leveraged by users to do the concurrent design for one space science mission.

When designing a product, the earlier the potential risks can be identified, the more costs can be saved, as it is easier to modify a design in its early stages. Several methods exist to analyze the risk in a system, but all require a mature design. However, by applying the concept of “common interfaces” to a functional model and utilizing a historical knowledge base, it is possible to analyze chains of failures during the conceptual phase of product design. This paper presents a method based on these “common interfaces” to be used in conjunction with other methods such as Risk in Early Design in order to allow a more complete risk analysis during the conceptual design phase. Finally, application of this method is demonstrated in a design setting by applying it to a thermal control subsystem.

Maschinen und besonders Anlagen werden meist in individuellen Prozessen entwickelt. Bereits in der Angebots- und Konzeptionsphase werden im direkten Austausch mit dem Auftraggeber unterschiedliche Varianten diskutiert und iteriert. Zur Bewertung der Varianten sind neben den Anschaffungskosten unter anderem laufzeitabhängige Größen wie Taktzeiten und Energieeffizienz zu untersuchen. Der Beitrag stellt einen Ansatz zur simulationsbasierten Untersuchung für die automatisierte Variantengenerierung von Anlagen vor.   The development of machines or plants is a very individual process. Within the conceptual design phase, many different variants have to be discussed with customers and adapted to their needs. For a decent evaluation of the different variants, many parameters beyond static values such as costs are important. Term-dependent values like cycle times and energy efficiency also have to be investigated. This paper presents a method for the automated generation of plant variants based on simulation.

Westinghouse has been a strong supporter of Reliability, Availability, and Maintainability (RAM) principles during product design and development. This is exemplified by the actions taken during the design of the 501F engine to ensure that high reliability and availability was achieved. By building upon past designs, utilizing those features most beneficial, and improving other areas, a highly reliable product was developed. A full range of RAM tools and techniques were utilized to achieve this result, including reliability allocations, modelling, and effective redesign of critical components. These activities began during the conceptual design phase and will continue throughout the life cycle of these engines until they are decommissioned.
