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

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

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

MySQL (Oracle) databases are widely used in the engineering world to store libraries of components that may be used across many diverse projects. This information is very useful for system engineers composing system architecture models (e.g. in SysML) from reusable building block library elements. A simple import of data is not enough to ensure that values of

Excel tables are small, inexpensive databases that are easy to modify for small teams of engineers, and which may contain libraries of components or tables of functions. Many engineering projects utilize tables in Excel that contain much of the same information that is needed by system engineers to model structure and interconnections in SysML. However,

The Martian by Andrew Weir (2014) is a great read and now a hit movie. The astronaut hero and the expert SysML modeler have several things in common. First, they have the ability to take a complex system and adapt and reuse its components to new purposes. Second, both do careful calculations of system performance
