One area in the biomedical and healthcare domain where MBSE has made significant progress is in medical device design and manufacture. At the same time, device suppliers use modern PLM (product lifecycle management) and CAD (computer-aided design) like other organizations engaged in complex engineering problems. The first figure below shows the SysML structural decomposition of

This blog post introduces the second installment in our series of notes outlining different scenarios for using Syndeia 2.0 to generate, connect, and compare Simulink and SysML models. Part 1 showed how SysML block and activity structures can be used to generate Simulink model reference structures, including both atomic and multi-signal ports. Part 2 will describe how

Efficiency in healthcare delivery has long been a target of systems engineering and operations analysis effort. Improvements in emergency room care, for example, can lead to better outcomes and better patient experience while reducing the cost of care. In this post, we apply simple parametric analysis to testing medical facility staffing and supply against requirements,

InterCAX and Georgia Tech collaborate to provide a lot of MBSE and SysML training.  After the introductory course on SysML language, new modelers are inclined to ask, “What next?” They are looking for guidance on how to start using modeling for their own work.  They want a process, a methodology, even a template, and these

The human cardiovascular system is extremely complex. The heart pumps blood into arteries, which subdivide into a finer and finer network of capillaries that supply oxygen and fuel and carry away waste products from the body’s tissues, and then recombine into veins that return the blood to the heart. A second loop sends blood through

In this fifth and final installment, we look at two examples from the important domains of CAD and simulation to illustrate the “Internet-of-Tools” concept as applied to our Smart Home Internet-of-Things model. In the first example, a CAD model is linked to structural blocks in the SysML model of the 4 Room Smart Home, so that changes

Healthcare, in the US and globally, faces a challenge: how to offer a broader range of preventative, diagnostic and therapeutic services to a greater number of consumers without a proportionate increase in cost or decline in quality. Systems Engineering can help address this challenge, but only if we accept that healthcare involves a wide range

This is the fourth in a series of technical notes describing the application of Model-Based Systems Engineering (MBSE) to the specification, design, procurement and evaluation of an Internet-of-Things (IoT) system. One advantage of an object-oriented modeling language such as SysML is that it becomes simpler to compose a model into a larger context. This section

A crucial thread in enabling model-based systems engineering (MBSE) for next-generation complex systems is to analyze system architecture by means of simulations and verify requirements continuously during design and development phases. The general steps in this iterative simulation-based design approach are as follows: Define system architecture (design model) Create a simulation model Run the simulation
