In the rapidly evolving landscape of modern infrastructure, understanding individual components in isolation is no longer sufficient. Systems of Systems (SoS) modeling emerges as a pivotal approach in this context, offering a holistic view of interconnected, independent systems that come together to form larger, more intricate networks. Complex infrastructure systems, such as urban transportation networks, power grids, water supply chains, and telecommunication infrastructures, often consist of multiple interacting subsystems, each with its own set of characteristics, behaviors, and objectives. SoS modeling allows stakeholders to examine how these subsystems interact, collaborate, and sometimes compete, providing insights into emergent behaviors, potential vulnerabilities, and optimization opportunities. By embracing this approach, city planners, engineers, and policymakers can ensure more robust, resilient, and efficient infrastructure systems capable of adapting to unforeseen challenges and ever-evolving demands.
