Combining the modeling and simulation perspectives of both Systems Engineering and Engineering Simulation can improve communications and coordination across the product development life cycle.
Systems Engineering has recognized the importance of models in a wide range of roles. Early in the development of a system, models may be used to understand the user domain, to define functions and concepts, and to capture system requirements across the levels of a system architecture. Such models may specify functional, interface, performance, and physical requirements, as well as other non-functional requirements such as reliability, maintainability, safety, and security.
Engineering Simulation has been an essential part of product development engineering across many industries and disciplines for decades. This work is typically performed by technical specialists with deep knowledge in their respective domains, and with expertise in specialized mathematical and analytical tools.
The SMS WG defines Systems Modeling and Simulation (SMS) as the use of interdisciplinary functional, architectural, and behavioral models (with physical, mathematical, and logical representations) in performing Model-Based Systems Engineering (MBSE) to specify, conceptualize, design, analyze, verify and validate an organized set of components, subsystems, systems, and processes.
The SMS WG communicates to the wider engineering community via the SMS Community. This consists of individuals who are either NAFEMS or INCOSE members, with an interest in the topic of Systems Modeling and Simulation but who are not necessarily experts in this area.
