System architecture modeling tools

Software Ideas Modeler is a lightweight and powerful tool for the creation of UML diagrams and some other diagrams. Requirements Engineering for better products. Following the guidelines for SysML laid out by OMG, Astah SysML represents a broad use platform perfect a wide variety of modeling tasks such as; specifying, analyzing, designing, verifying any number of complex systems.

These models are applicable in an even wider variety of systems driven fields including; hardware, procedures, facilities, personal information, software, and, of course, many more. It is designed to be easy to use, while still being powerful. Gaphor implements a fully-compliant UML 2 data model, so it is much more than a picture drawing tool.

You can use Gaphor to quickly visualize different aspects of a system as well as create complete, highly complex models. It is open source software and cross-platform. Crack the information silos and make more out of your models. Leverage the precision and richness of models in digital transformation and model based systems engineering throughout your organisation. They can now instantly create data-driven and customizable diagrams with beautiful graphics for the desktop or the web.

System engineers can filter data and show nested diagrams with varying levels of detail, and print or save the resulting diagrams. This is becoming increasingly important in application fields that are being shaped by digital transformation and also for progressively complex projects such as those seen in the auto industry, aerospace, and defense markets. Easy-to-use software engineering diagramming tool that supports all contemporary modeling notations.

With SysML support: Visualize your system hierarchy. Gain insight to interconnections between system components. Disclaimer , Privacy Statement. Try before you buy. Architectures or parts of them can sometimes be "tried out" during live exercises. This can either confirm an architectural approach for application to real-world situations or be the basis for refinement that better aligns the architecture with operational reality.

Architectures also can be used as a basis for identifying prototyping and experimentation activities to reduce technical risk and engagements with operational users to better illuminate their needs and operational concepts.

Taming the complexity beast. If a program or an effort is particularly large, models and views can provide a disciplined way of communicating how you expect the system to behave. Some behavioral models such as business process models, activity models, and sequence diagrams are intuitive, easy to use, and easy to change to capture consensus views of system behavior. Keep it simple. Avoid diagrams that are complicated and non-intuitive, such as node connectivity diagrams with many nodes and edges, especially in the early phases of a program.

This can be a deterrent for the uninitiated. Start with the operational concepts, so your architecture efforts flow from information that users and many other stakeholders already understand. Determining the right models and views. Once the frameworks have been chosen, the models and views will need to be determined. It is not unusual to have to refer to several sets of guidance, each calling for a different set of views and models to be generated.

But it looked so pretty in the window. A simple spreadsheet can be used for this purpose. This should happen early and often throughout the system's life cycle to ensure that the architecture is used. Figure 4 provides an example of a worksheet that was used to gather architecture requirements for a major aircraft program.

How do I create the right views? Selecting the right modeling approach to develop accurate and consistent representations that can be used across program boundaries is a critical systems engineering activity. Some of the questions to answer are:. Bringing dolls to life. If your program is developing models for large systems supporting missions and businesses with time-sensitive needs, insight into system behavior is crucial.

Seriously consider using executable models to gain it. Today, many architecture tools support the development of executable models easily and at reasonable cost. They are worth investigating to support reasoning about technology impacts to mission performance and internal system behavior, respectively. How much architecture is enough? Architecture models and views must be easily changeable. There is an investment associated with having a "living" architecture that contains current information, and differing levels of abstraction and views to satisfy all stakeholders.

Actively discuss this sufficiency issue with stakeholders so that the architecture effort is "right-sized. Penny wise, pound-foolish. Generating architecture models and views can seem a lot easier to not do. Before jumping on the "architecture is costly and has minimal utility" bandwagon, consider the following:. If the answer to one or more of these questions is "yes," then consider concise, accurate, concordant, and consistent models of your system.
