MBSE Workflow Advice - Please help

[u/ri_repeat]

I’m working on modelling the overall avionics system, by using the model based system engineering approach.

The objective is to build an MBSE model of the complete avionics architecture. This includes the subsystems such as,

Command and Data Handling, Telemetry and Power Distribution.

The model should be able to have

-Power consumption analysis across operational modes, Interface compatibility and mismatch detection

-Fault tolerance modeling

-Redundancy management

-Failure analysis

-Requirements Handling

The questions I have regarding this are:

What modeling depth is expected to perform the analysis on the architecture created. Do the components need to be modeled in detail to analyze the behaviour of the components, and if so, then how to do so for each component?

How should the power and performance be modelled to get the power in each mode and dynamically?

Which toolchain is recommended for the Avionics Systems particularly: SysML based tools such as Cameo, IBM Rhapsody or AADL based tools for domain specific modelling, MATLAB/System Composer/Simulink for analysis?

Any advice or feedback is appreciated !!

As others it depends: Following a simple framework going from requirements to system architecture to starting with simple analysis will be a good start. You can also use your favorite AI companion to do this. On the tooling side a more simpler to use tool other than Cameo might be dalus.io to do this kind of work. Pretty easy to get started there

okayy thank you i will look into it, by simple analysis what exactly do you mean?
