This category covers the System Modeling Language basics.
This post is based on the paper “SysML for embedded automotive systems: SysCARS methodology, Jean Denis PIQUES”. SysCARS (System Core Analyses for Robustness and Safety) is a methodology developed by Valeo that is designed to enable system designers to perform modeling activities sequentially and efficiently using SysML. This methodology is very useful for system engineers … Read more
In this post, we will introduce the MBSE Grid method, one of the MBSE (Methods of Model-Based Systems Engineering) methodologies. MBSE Grid This content is based on the paper “MBSE Grid: A Simplified SysML-Based Approach for Modeling Complex Systems.” The authors of the paper include Aurelijus Morkevicius. The MBSE Grid framework can be seen in … Read more
In this post, we will learn about ‘Object-Oriented Systems Engineering Methodology (OOSEM)’, one of the modeling methods. Even if you have knowledge of SysML, you can often feel at a loss about the starting point and progression sequence when designing a system in real life. Modeling Method plays a role in resolving these difficulties. A … Read more
How to draw a State Machine Diagram with EA For an example of a State Machine Diagram (stm) to be drawn using EA, we will use the diagram below from the State Machine Diagram Chapter of Lenny Delligatti’s SysML Distilled. First, create a project and create a package. State Machine Diagram The model element that … Read more
Understanding Stm Diagram Event Pseudostate Region In SysML, events are one of the key elements of a state machine diagram. Events cause changes in the state of the system and are therefore essential for understanding the dynamic behavior of the system. SysML defines four main types of events: signal events, call events, timed events, and … Read more
Understanding Stm Diagram State and Transition State machine diagrams in SysML are powerful tools for visualizing the behavior of complex systems. This article will guide you through the basic concepts of state machine diagrams and explain important points to consider when creating such diagrams. 1. Introduction to State Machine Diagrams A state machine diagram graphically … Read more
How to draw a Sequence Diagram with EA For an example of a Sequence Diagram to be drawn using EA, we will use the diagram below from the Sequence Diagram Chapter of Lenny Delligatti’s SysML Distilled. First, we will model the blocks that will participate in the Sequence Diagram. Create a new project, create a … Read more
Understanding Seq Diag Constraints Fragment Decompose Execution Specifications An execution specification is a mechanism for explicitly indicating the start and end of execution of specific actions in a sequence diagram. This allows you to more accurately understand and document the complex flow of system dynamic behavior and interactions. The use of execution specifications highlights the … Read more
In this article, we will explain the concept of sequence diagrams and specifically look at how they can be used in systems engineering. Understanding Seq Diagram LifeLine and Message Sequence diagrams in SysML provide a visual representation of how components interact within a system and how that interaction unfolds over time. Each component (lifeline) and … Read more
How to draw a Activity Diagram with EA Starting with Activity Diagram, we will draw some of the Activity Diagrams shown as examples in Chapter 9 Activity Diagram Chapter of “Practical Guide to SysML: The System Modeling Language” 2nd Edition using EA. This is because I think it would be more useful for readers to … Read more
