Consider a healthcare facility with independent software systems for each department. A system engineer is tasked with developing a message exchange system between the departments based on the HL7 Version 2 standards. She begins by describing the interfaces and content exchanged between departments based on SysML interface blocks. The flow properties of these interface blocks are typed

In Part 1 of this series, we connected individual requirements in DOORS NG to requirements and other elements in SysML. Greater challenges arise when we need to map requirement structure and organization between tools, because different tools organize requirements in significantly different ways. SysML tends to organize requirements in simple tree hierarchies using containment relationships.

As a project moves from architecture definition to component design, new software tools, such as mechanical computer-aided design (MCAD), become part of the engineering process. The impact of component design decisions needs to be continuously evaluated at the system level. The Syndeia interface for PTC Creo supports a number of use cases from either MagicDraw

In Part 1 of this series, we explored how Syndeia 3.0 generates global displays of connections between various engineering software tools. While these global displays (e.g. Figure 1) provide a snapshot of graph complexity, some very important use cases require us to trace out chains of individual connections and identify those model elements that may

Syndeia 3.0 offers a new option for a DOORS NG interface for MagicDraw and Rhapsody SysML modeling tools. The integration of requirements databases with system architecture modeling (SysML) is of high value to the practitioners in the field of MBE/MBSE. Although several solutions have been offered in the past, they address only the basic use case(s). Syndeia

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,

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
