“…By analyzing big data obtained from DSE later, it is possible to find combinations of design variables for the ADCS statistically that satisfy the required pointing accuracy from the optical camera system. One can use the design structure matrix (DSM) to find whether feedback processes exist [24,25]. The integrated design environment can be developed by using Excel TM if all the system algorithms are developed with the same tool; however, it is recommended to use commercial tools such as Model Center TM [26] or iSight TM [27] because there are frequent cases where other tools such as executables files and routines of MATLAB TM are used.…”

The space mission analysis and design process defines a space system at the system level to accomplish space mission objectives. Although the traditional process is well established and comprehensive through several years of experience, we propose a novel design process framework in this paper to aid the traditional process focusing on the following areas of improvement: (1) clarification of the direct connection between mission objectives and final system-level baseline design and requirements, (2) development of a comprehensive quantitative judgment criterion to evaluate various design alternatives, (3) derivation of system drivers and critical requirements after obtaining sufficient design knowledge based on the analysis of big data obtained from exploration of entire design space using an integrated design environment, and (4) system optimization even at the system level with a holistic perspective to guarantee that the baseline design meets the mission objectives. Examples of design steps in the proposed framework are characterizing stakeholder needs and engineering characteristics, building an integrated design environment, exploring and analyzing design space, optimizing system-level design, and elaborating mission utility to ensure an efficient mission-oriented design approach. The proposed framework is implemented in an example space mission involving quantum cryptographic communication. Accordingly, we demonstrate that the proposed framework provides an efficient mission-oriented satellite system-level baseline design.

“…Modular subsystems that replace legacy subsystems: requires a modular architecture with sufficient design margin to accommodate the new upgrades With the exception of items (4) and ( 5), each of these types of systems relies on the reuse of existing technology and capability. Knoll, Fortin, and Golkar (2021) identify that complex systems often involve concurrent design and therefore changes in one discipline must be propagated to the other disciplines. Decisions made in one discipline are not isolated events; they impact every other part of the system.…”

The Space Development Agency (SDA) is a constructive disruptor within the Department of Defense, tasked with rapidly acquiring and delivering space‐based capabilities. SDA delivers dozens of satellites on two‐year cycles and this pace requires defined processes to ensure that the technology exists to support the required capabilities. SDA has developed a process called List, Evaluate, Achieve, Procure (LEAP) which is used to identify technologies that require additional development resources to meet both current Warfighter needs and those that will occur in the future. This paper provides an illustrative example of SDA applying the LEAP process to the development of SDA's optical communications terminals, demonstrating how it is used to identify critical technologies to be supported through investment opportunities that augment the system acquisitions.

“…For paper-ready demonstration, we developed and used a Future Firefighting (FF) model example, rather than the students' project on which we evaluated our implementation. FF systems had been used before to demonstrate MBSE-Conceptual-Design and modeling extensions, 21,23,36,37 and are rather self-explanatory. In our case, the customer needs are to provide an innovative technical solution to firefighting, which can minimize response time to fire events, and the risk to humans.…”

“…In our case, the customer needs are to provide an innovative technical solution to firefighting, which can minimize response time to fire events, and the risk to humans. It encompasses requirements for sensing capability similarly to the FireSAT example, 21 but also situation awareness for ground control, and timely response. It addresses both the firefighting demands and the public needs.…”

“…JPL further addressed Conceptual‐Design embeddedness into the full system lifecycle, described as a set of concept maturation iterations, 20 from Cocktail Napkin to Integrated Design. Recently, Knoll et al 21 . defined a process model for Concurrent Conceptual Design based on a survey of best‐practices in the space industry 7 to include: (1) a multi‐disciplinary team of experts; (2) co‐located in a shared work space (3) producing an integrated system model; (4) using collaboration tools; and (5) following a managed design process.…”

Conceptual‐Design is an early development phase, where innovation and creativeness shape the future system/product. Model‐Based‐Conceptual‐Design (MBCD) attempts to use best‐practices of Model‐Based‐Systems‐Engineering (MBSE) to gain the envisioned benefits of model connectivity. Using MBSE supporting tools can transform Conceptual‐Design into a digital‐engineered process but may impede creativity and innovation. Concurrently, the design domain offers specific methods and tools for innovative Conceptual‐Design. In the current study, we explore an existing Conceptual‐Design framework and offer MBSE interpretation and tools extensions needed for its digital implementation. Through such exploration we highlight MBCD specific insights and discuss modeling‐innovation interrelations. The implementation was accomplished using a domain‐specific enabling software package on top of a market‐accepted UML/SysML platform, extending the language definitions, where appropriate. The framework guided extensions allow generation of innovative bottom‐up alternatives, solution integration, and solutions’ comparison. The use of modeling is shown to offer clearer process definition, specific methods assistance, and alternative ranking—both manually and automatically. Consequently, MBCD is accomplished, which supports innovation, while being digitally connected to full‐scale‐development models and the organizational assets at large. Through integration into the orderly Systems‐Engineering process, traceability is maintained, and repeated iterations are supported, where conceptual decisions may be revisited. Additionally, through the introduction of an assets’ catalog, cross‐organizational knowledge sharing is accomplished. The paper presents samples of the extensions, using a simplified example of technology design for Future Firefighting. The value of incorporating Conceptual‐Design specific methodology and tools is evaluated through feedback from multiple domain experts. Discussion and future research directions are offered.
