The rising complexity and interconnectedness of contemporary systemsengineering solutions have spurred the development of systems-of-systems (SoS). Within a SoS, we find interconnected constituent systems (CSs), each possessing individual capabilities and managerial autonomy. For effective management of a SoS, a dedicated orchestration mechanism is crucial. However, currently, there is a lack of a well-defined internal structure or an understanding of roles and interactions between sub-parts of the Orchestrator. This paper proposes a framework for SoS orchestration, identifying distinct actors and their functional roles for an effective SoS operation. Our framework consists of two main groups: SoS Governors (handling legal and financial aspects) and the Orchestrator (responsible for the overall SoS operation). Key actors within the Orchestrator are identified and described, including the Goal Transformer, Registrar, Composer, Executor, Cartographer, Data Curator, and Translator. The paper concludes by discussing the dynamic collaboration between orchestration actors and the significance of clearly defining these roles for complex SoS management. This study offers a foundation for future research and practice in SoS orchestration, potentially enhancing these complex systems' resilience, effectiveness, and overall management.

Accurate mapping of software requirements to tests is critical for ensuring high software reliability. However, the dynamic nature of software requirements throughout various mission phases necessitates the maintenance of traceable and measurable requirements throughout the entire mission life cycle. During the development phase, a predictable and controlled deployment, testing, and integration of software systems can strongly support a mission's rapid innovation. Similarly, during the operation phase, timely application of patches and efficient evaluation and verification processes are vital. To address these challenges, we propose a novel method that combines Natural Language Processing (NLP) and Machine Learning (ML) to automate software requirement-to-test mapping. This method formalizes the process of reviewing the recommendations generated by the automated system, enabling engineers to improve software reliability, and reduce cost and development time.

Although the modernized Maritime Transportation systems (MTS) have experienced meaningful advancements and benefits from the adoption of Internet of Things (IoT) technology, security, reliability and privacy issues have increased extensively. The federation of multiple maritime stakeholders in the flow of transportation management and schedule exacerbates these issues, with the MTS to encounter escalating attacks dealing with data manipulation and unauthorized access that pose risks of high severity in MTS. Therefore, the maritime IoT infrastructures require to transition from centralized to distributed networks with access control policies, strong identity authentication and private communication systems that cannot be manipulated by unauthorized stakeholders. Blockchain has recently emerged as a key technology for addressing data security and privacy issues. However, this integration can introduce substantial delays in maritime services. In this paper, we propose the SEAGuard framework, particularly designed and developed for addressing security and privacy issues specific to MTS. A virtualized testbed is built to evaluate the SEAGuard framework that is developed on-top of Hyperledger Fabric and the InterPlanetary File system (IPFS). The results illustrate exceptional performance metrics with minimum latency and high throughput, less than 4 ms and more than 70 transactions per second, respectively.
