The military of the Republic of Korea utilizes technology readiness assessment (TRA) to quantitatively evaluate the maturity of domestic technologies. TRA is a key tool for determining the research and development potential in the country. As TRA employs hardware (HW)-oriented technology readiness levels (TRLs), it is suitable for independently assessing individual technologies. However, it has limitations in terms of evaluation from a system-integration perspective. Additionally, the results of checklist-based assessments are highly likely to involve subjectivity, which may yield sparse quantitative insights. This study proposes an enhanced TRA framework in which TRA procedures and criteria are redefined from the systemintegration perspective. A framework that can overcome the limitations of the current TRL and TRA frameworks and enable easier, more intuitive assessments is developed. The proposed framework distinguishes between a technology element and a critical technology element (CTE) in terms of HW, software (SW), and interface (IF) and redefines TRLs. Under this framework, TRA is performed according to the TRLs that are redefined in terms of HW, SW, and IF; considering risk management, the lowest evaluation value is used as the system maturity level. The proposed CTE selection method minimizes external evaluator interventions by considering the quantitative goals of the key required operational capabilities, development difficulties, and applications of commercial off-the-shelf technologies. The effectiveness of this framework is confirmed through a case study involving three systems of systems. The results of this study can inspire research at the framework level and contribute to the improvement of existing TRA systems.

“…In these cases, the remaining design loops should be shortened as much as possible to reduce the time and cost of the project. To do this, the elements closer to the main diagonal should be drawn [13]. After employing these algorithms, the following subprocesses that can be done independently of each other could be identified.…”

Satellite design process is an interdisciplinary subject in which the need for collaboration among various science and engineering disciplines is evident. Meanwhile, finding an optimal process for conceptual design of a satellite, which can optimize time and cost, is still an important issue. In this paper, based on system engineering approach, an optimal design process is proposed for LEO satellite constellations. In the proposed method, design process, design sequences, and data flow are established. In this regard, the conceptual design process is divided into two levels of mission (or constellation) and system (or satellite) as well as 15 main activities based on the mission profile, previous experiences of the authors, and existing literature. Then, the relationships between these activities have been determined by considering the importance of relationships according to their priority. Finally, these relations are optimized based on design structure matrix (DSM). By utilizing this approach, system design process of a telecommunication satellite constellation in LEO is formulated in conceptual design phase. Performance and capability of the proposed approach in optimal design process of the satellite constellation are investigated by comparing the outcome with existing results in the literature.
