Model-Based Engineering (MBE)
Also known as: MBE
In engineering, Model-Based Engineering (MBE) is an approach in which models are the primary working and evidence artifacts. Documents are derived from models rather than being the reference themselves.
- Systems engineering
- Data and interfaces
In one sentence
Model-Based Engineering (MBE) makes models the primary working and evidence artifacts across disciplines, with documents derived from them.
Example
A CNC machine builder uses MBE: mechanical CAD, electrical design and the safety function model are the references, and wiring diagrams and parts lists are generated from them.
How it applies
- Evidence: If models are the evidence, they need the same controls as documents: versions, approvals and audit trails. See model governance.
- Integrated systems: MBE works across tools only if the links between models are maintained. A digital thread connects them over the lifecycle.
- Technical documentation: Generated documents must stay synchronized with the model version. Technical writers should know which model state a generated output reflects.
- Compliance: Regulators and notified bodies generally review documents. Plan how model content is exported into a reviewable technical file.
MBE vs. MBSE
MBE is the general approach across all engineering disciplines. MBSE applies it to systems engineering: requirements, functions, architecture, interfaces and behavior of the system as a whole.
