Concurrent conceptual design sequencing for MBSE of complex systems through design structure matrices

Whilst Concurrent Conceptual Design (CCD) has been performed for many years at facilities such as: the Concurrent Design Facility at ESA and the Project Design Center at JPL-NASA, the sequencing know-how resides in their communities of practice. This paper strives to explain how a sequencing algorithm based on Design Structure Matrices can be used as an instrument to facilitate the interaction between disciplines during CCD studies for Model-Based systems exemplified with two case studies

Evaluierung einer cloud-native Entwicklungsumgebung für das modellbasierte Systems Engineering für Raumfahrtsysteme

MBSE must support a wide variety of configurations because it works with a variety of soft-ware and interfaces. The resource requirements of the software used can exceed the capaci-ties of a local computer. Cloud computing promises to meet the increasing demands. MBSE tools exist for space systems, but none of these tools take advantage of a cloud environment. In recent years, open-source projects such as Eclipse Theia, EMF.Cloud and Eclipse Che have been developed which make it possible to develop a cloud-native development envi-ronment for MBSE. However, no development environment has yet been implemented that takes advantage of the cloud for computation. To determine the requirements for an MBSE tool in the cloud, a questionnaire with two rounds is conducted. In the first round, requirements are collected as user stories. In the second round, the requirements are categorized according to the Kano model. A total of 52 requirements were identified, of which 19 were identified as enthusiasm, 20 as basic, 3 as performance and 10 as irrelevant. The performance analysis showed that complex computations scale similarly to local execution. If simpler computations are performed, the local computation is significantly faster due to the elimination of the com-munication overhead
