Model-Based Systems Engineering
Model-Based Systems Engineering (MBSE) is the practice of developing a set of related system models that help define, design, analyze, and document the system under development.
These models provide an efficient way to virtually prototype, explore, and communicate system aspects, while significantly reducing or eliminating dependence on traditional documents. MBSE is the application of modeling systems as a cost-effective way to explore and document system characteristics.
By testing and validating system characteristics early, models facilitate timely learning of properties and behaviors, enabling fast feedback on requirements and design decisions.
Historically, system decisions for requirements, designs, tests, interfaces, allocations, and others are maintained in a variety of sources, including documents, spreadsheets, domain-specific tools, and sometimes even on paper.
The MBSE approach is a holistic one to manage system information and data relationships, treating all information as a model.
An economic analysis demonstrates that there is a significant advantage to project performance by applying a model based systems engineering (MBSE) approach.
An MBSE approach makes the engineering processes on a complex system development effort more efficient by improving requirements completeness, consistency and communication. These are seen in engineering processes involved in requirements management, concept exploration, design reuse, test and qualification, Verification and Validation, and margins analyses.
An MBSE approach has been proven to be most effective at improving defect prevention strategies. The approach is found to enhance the capability to find defects early in the system development life cycle (SDLC), when they could be fixed with less impact and prevented rework in later phases, thus mitigating risks to cost, schedule and mission.
The following are some desirable characteristics of MBSE approaches:
- Emphasizes a precise and complete System Architecture Model “blueprint,” typically organized using an Architecture Framework with multiple Views/Viewpoints, as the primary work artifact throughout the System Development Life Cycle (SDLC).
- Promote the use of open standards for architectural modeling and tool interoperability(e.g., SysML, UML 2, XMI, AP233), where these open standards are used to specify the System Architecture Model and to serve as a lingua franca among Systems Engineers and other stakeholders (Software Engineers, Electrical Engineers, Mechanical Engineers, Customers, etc.).
- Ensures that the System Architecture Model is architecture-centric to the extent that all model elements must maintain structural and functional integrity relationships, and support full derivation traceability across all system stakeholder Views and Viewpoints.
- Combine traditional Systems Engineering best practices with architecture modeling best practices.
It’s generally believed among systems engineers that MBSE delivers such a wide range of benefits because it introduces additional consistency and continuity, and because it is both human- and computer-understandable, and logically verifiable.
Over the past few years MBSE has grown in usage because a common model helps engineering and stakeholders effectively collaborate and help to develop a common understanding.
This is important because it’s not uncommon for mission systems to be created by people with different interests and skills who must somehow find a way to work together to complete projects.
All indications are that MBSE is becoming even more popular as a systems engineering process paradigm. Some would go so far as to say that MBSE methodology is responsible for pushing digital engineering forward.
MBSE work forces use digital representations of systems and components–versus documents and spreadsheets–to communicate concepts and information unambiguously.
Model-Based Systems Engineering Training Course by Tonex
Model-Based Systems Engineering (MBSE) Training Courses introduce you to the notions and philosophies behind Model-Based System Engineering. They also review the tools, models and requirements associated with MBSE in various fields.
Some things you will learn:
What Is A System?
INCOSE refers to a system as the combination of elements constructed or gathered together, produce the results that are not reachable by each individual element, alone.
In addition, the elements of a system are connected to each other through defined relationships in such a way they demonstrate coherency and neat organization.
Moreover, the system elements should be arranged in a way that follows a defined objective or goal. In fact, the components of a system should be built in order to accomplish sets of specific tasks with the objective of generating the desired results.
The design of the system should illustrate the following characteristics:
In What Language Does A System Communicate?
The system language varies with the system properties mentioned above — the entities, attributes and relationships. The system language is a critical matter as it describes and shares the system characteristics between the engineers of a team as well as to other stakeholders.
The system language enables each system to be presented in a hierarchical approach, which allows demonstrating the system in its subunits. Such subunits are traditionally named:
Subunits divide into subsystems, then subsystems into assemblies, assemblies into subassemblies and finally subassemblies into parts.
The parts of a system interact with each other to produce the operation of the whole system. Obviously, all the elements of the system have to function as designed so that the entire system can operate accurately. Nevertheless, how the operation of each individual element can impact the operation of the entire system is not clear. That is because the impacts of interaction within the system are often very complicated.

- Higher quality by delivering a sharp and precise model of the system that can be evaluated for coherency, properness and wholeness.
- Enhanced methods of gathering and re-using information by getting information in more organized approaches and empowering built-in concept mechanisms inherent in model driven approaches.
- Improved ability to train the systems engineering fundamentals by demonstrating a sharp vision of the ideas behind.
More About MBSE
MBSE is a holistic, systems engineering approach centered on the evolving system model, which serves as the “sole source of truth” about the system. It comprises system specification, design, validation and configuration management.
The notion and philosophy that backs up MBSE came from the need to create a means to facilitate analyzing and understanding complex systems via modeling. Modeling allows you to clarify the requirements, design, evaluation, verification, and validation activities associated with the system being studied. MBSE can be applied in any stage of the developing a system from the conceptual design, through development and to entire life cycle phases.
Model-based systems engineering essentially demonstrates a process of thinking. It offers a framework to allow systems engineering personnel to be productive and reliable during the entire process.
The MBSE methodology contains models that consider the entire engineering problem as a whole, employ a consistent language to describe the problem and the solution, create a well-studied solution, and comprehensively fulfill all the system requirements demonstrated by the problem. These tools associated with model-based systems engineering are critical when seeking a solution to the systems design problem.
MBSE focuses on substituting the document-based techniques to enhance the practice of systems engineering by completely comprehending the definition of systems engineering procedures.
