Systems Modeling Language (SysML) Solution

Examples

There are a few samples that you see on this page which were created in the ConceptDraw DIAGRAM application by using the SYSML solution. Some of the solution's capabilities as well as the professional results which you can achieve are all shown here on this page.

All source documents are vector graphic documents which are always available for modifying, reviewing and/or converting to many different formats, such as MS PowerPoint, PDF file, MS Visio, and many other graphic ones from the ConceptDraw Solution Park or ConceptDraw STORE. The SYSML solution is available to all ConceptDraw DIAGRAM users to get installed and used while working in the ConceptDraw DIAGRAM charting and drawing software.

Example 1: SysML Diagram — Builder Design Pattern Sequence

This diagram was created in ConceptDraw DIAGRAM using the Block Definition Diagram library from the SysML solution. An experienced user spent 20 minutes creating this sample.

This SysML Sequence diagram sample is based on the “Builder design pattern sequence1.png” file from the Wikimedia Commons and illustrates a Builder design pattern, which is one of the 'Gang of Four' design patterns. The Builder pattern is used to create complex objects with constituent parts that must be built in a specific order, provides flexible ways for solving recurring design problems and object creation problems in object-oriented programming. It allows separating the complex object construction from its representation and ensures creation of different representations of a complex object. Besides, the Builder pattern lets you vary a product’s internal representation, ensures the control over all steps of the construction process, and allows encapsulating the code for construction and representation. The same model can be used in many different products. This SysML Sequence diagram shows the run-time interactions between aClient, aDirector, and aConcrete Builder objects, which sequentially call the corresponding functions.

Example 2: SysML Diagram — Identity Requirements Diagram

This diagram was created in ConceptDraw DIAGRAM using the Block Definition Diagram and Allocations libraries from the SysML solution. An experienced user spent 25 minutes creating this sample.

This SysML example was created based on the SysML identity requirements diagram from the FreeIPA website. Requirements diagrams exist in their own diagram subcategory — they use both structural and behavioral elements to describe which objects require what actions to develop the process. This diagram describes the requirements for upstream identity providers and identities processing at the moment when they enter the local domain. You can find a prototype implementation of a "merged domain" in a collaboration context. The identity merging service contains the information necessary to bind against upstream identity sources. Local groups can contain users from local and upstream identifiers, the same username is used for all hosts and services in the domain, attribute values must be locally unique, clients in the local domain do not require credentials in the upstream domain. The following are implemented: local control over user attributes, local management of conflicts between them and centralized management of all identities to which local machines and services have access.

Example 3: SysML Activity Diagram

This diagram was created in ConceptDraw DIAGRAM using the Activity Diagram library from the SysML solution. An experienced user spent 10 minutes creating this sample.

This SysML Activity diagram example was designed based on the chart from the "SysML Modelling Language explained" document published on the Official OMG SysML site. SysML Activity diagram is one of the most common ways in systems engineering used to break down a process into all possible steps. It clearly presents the process steps and displays input and output pins. The SysML extends the opportunities of a popular UML language, in particular the management capabilities to support disabling of actions that are performed, the definition of continuous or discrete flow rate, as well as the rate and probability on the control or object flows. The SysML diagrams of different types created using ConceptDraw DIAGRAM SysML and UML tools make a process easily understandable and visually engaging. Besides, their construction with ConceptDraw's SysML solution drawing tools is fast and easier than ever, simply take ready-made objects from the vector stencils libraries and arrange them in a clear diagram.

Example 4: SysML Block Definition Diagram

This diagram was created in ConceptDraw DIAGRAM using the Block Definition Diagram library from the SysML solution. An experienced user spent 20 minutes creating this sample.

This SysML Block definition diagram example was designed based on the illustration from the "Template: OASIS: FunctionalBreakdownStructure" webpage published on the OASIS website. The Block definition diagram is based on the UML Class diagram, with special restrictions and extensions predefined by the SysML specification. It lets describe your system structure and model the system hierarchy, present the blocks, their properties and features, as well as outline the structural relationships and dependencies between these blocks. This sample presents a Function breakdown model and visualizes how a functional breakdown is represented in the PLCS PSM (PLCS Platform Specific Model). The PLCS PSM objects are required to represent the template FunctionalBreakdownStructure. Using SysML ensures that your diagrams will be universally understood by other system engineers and all stakeholders. The ConceptDraw DIAGRAM and SysML solutions fully support the SysML notation and provide the professional tools to simplify the systems engineering process and create professional-looking documents using a standardized notation.

Example 5: Use Case Restaurant Model

This diagram was created in ConceptDraw DIAGRAM using the Internal Block Diagram and Activity Diagram libraries from the SysML solution. An experienced user spent 15 minutes creating this sample.

The best system models allow clearly offering the information according to the system, with structure and workflow easily inferred from concise and coherent graphic elements. The SysML solution makes ConceptDraw DIAGRAM the most effective and powerful design choice for system engineers. This sample depicts a model of a restaurant business in a form of Use Case diagram and was designed based on the Wikimedia Commons file "Use case restaurant model.svg". The interactions between a restaurant business system and its primary stakeholders — business actors and business workers are illustrated. Four actors (Client, Chef, Waiter, and Cashier) are involved in a process and depicted in this diagram with men pictograms. At this, the Waiter, Chef, and Cashier are considered as a part of the restaurant system and are the business workers, while the business actor Client is outside a considered system and directly interacts with it. All possible use cases, the usage of a system by actors and interactions between them to achieve the main goal are presented.

Example 6: Package Diagram – Deployment Model Structure

This diagram was created in ConceptDraw DIAGRAM using the Internal Block Diagram and Activity Diagram libraries from the SysML solution. An experienced user spent 15 minutes creating this sample.

This SysML Package diagram example illustrates a Deployment model structure and was designed based on the Wikimedia Commons file “Deployment Model Structure.PNG”. The SysML Package diagrams are the ideal type of diagrams to be used to visually depict the functionality of a software system and all dependencies between the packages that make up a model. As general, the packages are a universal mechanism for organizing the model elements and diagrams into groups, to group semantically related elements. They are used to depict the different layers of a software system, so to visualize the layered architecture, and may include the use cases. The communication mechanisms can differ from the layer to layer, the labels on the dependencies help to clarify and indicate the used ones. One can benefit from the use of Package diagrams as a way to depict the dependencies between the elements for the systems of any size and complexity, especially they are useful for large scale systems. Due to ConceptDraw’s SysML solution the model based systems engineering is now easier than ever.

Example 7: SysML Parametric Diagram

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the SysML solution. An experienced user spent 15 minutes creating this sample.

This example presents a SysML Parametric diagram constructed on the basis of a diagram from the "SysML Modelling Language explained" document published on the OMG Systems Modeling Language website. The Parametric diagrams are intended to conduct the system modeling and system analysis according to different system parameters, such as performance, reliability, and others. The analysis is realized by means of defining the constraint blocks. The block constraints are created as constraint properties in Parametric diagrams and are included to them along with other parameters. One can observe six constraint properties of type in a proposed diagram: SineWave, Mult, Delay, Add2, and Buffer; some of them are linked with each other. The inputs are represented in the green box at the left and the outputs in the blue one at the right. The system parameters are split between both of them and are associated with constraint property parameters. The connectors are used to link all system properties and constraint properties.

Example 8: SysML State Machine Diagram

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the SysML solution. An experienced user spent 15 minutes creating this sample.

This sample offers a SysML State Machine diagram concentrated on the internal system changes and specifying its dynamic behavior. The sample was constructed in ConceptDraw DIAGRAM based on the “UML state diagram.png” Wikimedia Commons file. The State Machine diagrams have a wide spectrum of applications — from software development to business processes modeling, including the modeling of complex behavior systems. The traditional form of the State diagram with a common notation is preserved in this SysML diagram. The circles define the initial and end states, the rounded rectangles denote the states that an object pass in response to events during its life. The events that cause the changes of states are also depicted. So, the State Machine diagram is a kind of dynamic behavioral diagram that clearly represents the sequence of states of an object during its lifetime in response to occurred events, which may result in side-effects. The arrows connecting the state symbols describe the transitions between the corresponding states.
