The Internet of Things (IoT) holds enormous promise of new capabilities for users and new opportunities for businesses. It also presents enormous challenges to systems engineers. Model-Based Systems Engineering (MBSE) potentially provides an efficient way to address those challenges, being holistic, integrated, flexible and object-oriented. To explore this promise, Intercax has started a series of technical notes on modeling the Smart Home, a well-known example of the IoT, using MBSE, SysML and Syndeia, an integration platform linking systems engineering to the rest of the engineering process.
In Part 1 of this series, we described an MBSE process going from requirements specification to a detailed multi-level functional design. In Part 2 we created a structural reference architecture, allocated functions to structural elements, added parametric modeling for cost and power consumption, and imported IoT component product data from external databases
In this technote (Part 3), we will:
The next notes in the series describe how this model can link to models of different type and scale, including CAD models of the home, time-varying simulation models, and larger SysML models, e.g. the Smart Grid for electrical power.
