The Advanced Quantitative Precipitation Information (AQPI) System provides San Francisco Bay Area users with a single source of meteorological observations ranging from national weather model forecasts to local high resolution radar quantitative precipitation estimations (QPE). As a complex and sociotechnical system, AQPI lends itself to following the complex, Large-scale, Interconnected, Open, Sociotechnical (CLIOS) process defined by Joseph Sussman. Following the CLIOS process and separating the physical model from the institutional sphere, a systemsengineering approach naturally aligns with the Model-Based systemsengineering (MBSE) methodology. Using block diagrams and internal block diagrams to capture the physical system, the engineer expresses the institutional sphere using behavioral modeling of use cases and activity diagrams. An MBSE behavioral analysis model for AQPI was developed in 2021 based upon the project concept. This preliminary model defined a foundation for the development of an AQPI Digital Twin. systems mature from concept through implementation, and Digital Twins are no different. In 2022, AQPI hosting transitioned from National Oceanic and Atmospheric Administration (NOAA) to the Cooperative Institute for Research in the Atmosphere (CIRA). With the completion of the transition, the AQPI model required an update to match implementation as of April 2023. Using capabilities-based requirements analysis, the updated AQPI model matures a step closer to becoming the Digital Twin of the AQPI system and a single source of truth for development and system evaluation in support of operations and maintenance.

Cyber-physical swarms represent a paradigm shift in distributed systems, mirroring characteristics akin to natural swarms, such as self-organization, scalability, and fault tolerance. This paper delves into these complexsystems, characterized by vast networks of cyber-physical entities with limited environmental awareness, yet capable of exhibiting emergent collective behaviors. These systems encompass a diverse array of scenarios, ranging from swarm robotics to the interconnectivity in smart cities, as well as the collaboration among augmented humans. The engineering of such systems presents unique challenges, primarily due to their intricate complexity and the spontaneous nature of their collective behaviors. This paper aims to dissect these challenges, offering a clear delineation of potential approaches. We present a comprehensive analysis, shedding light on the intricacies of engineering cyberphysical swarms and discussing modern solutions in engineering collective applications for such systems.

This article considers the program description, which is implemented through an operator's console or mobile phone to assess simultaneously the reaction of each participant in the experiment and the group as a whole to visual triggers that can vary in two ways: the digit value (from 0 to 9) - the digit color. Once the experiment is completed, individual and group performance scores of the complex sensorimotor reaction of the participants are displayed on the monitor screen, and the corresponding system database is generated for further processing and analysis of the results. Running the experiment with a program to test the sensorimotor reaction of a computer operator ensured high reliability in selecting computer operators and increased the technological capacity of the assessment by determining the efficiency of the complex sensorimotor reaction of a human operator rather than the time. This article provides the results of assessing the effectiveness of the complex sensorimotor reaction of a computer operator under group and individual conditions and presents their comparative values.

complexengineering projects are usually developed by alliances. An alliance is a form of system of systems with at least one common goal. However, there are more risks in alliance than conventional thinking acknowledges. As the project progresses, these risks become visible and hard to eliminate. This paper presents a new system of systems architecture that assists in identifying these risks. Risks are identified from conflicting interactions between systems. Furthermore, the new architecture framework provides a quantified method to prioritise across interaction types so that appropriate resources can be applied to mitigate the most critical risks.
