Should I do event tree modeling in simulink or via algorithm ?

Below you will see an event tree which I wish to simulate for a flight safety tool I am designing. I am thinking of using simulink considering future integration of my program with sensors which provieds real time data. I am thinking of using probablity of failure for the events stated in the image to be the factor moving ahead in the tree and the end points as the stopping point for my simulation. The project is still in the intital stage.

Project requirements:

1. Ability to solve all the branches
2. Selection of branch based on the highest probablity of failure correspoing to the event
3. Less computation time

Simulating the above something like this ?

Hi Mrunal,

After reviewing the requirements you have presented, it appears that Simulink would be the optimal choice for simulating the event tree of your flight safety tool. Simulink is a graphical programming environment that allows you to model and simulate dynamic systems using visual block diagrams, making it well-suited for handling complex event trees and real-time data from sensors. Moreover, Simulink can be used in combination with Stateflow and SimEvents to create intricate event-based models that enable you to analyze the behavior of your system and optimize its performance under different conditions.

Simulink offers the ability to select branches based on probability and provides results quickly with reduced computation time. Nonetheless, it's crucial to note that both MATLAB and Simulink are robust tools that can be used in tandem, depending on your specific requirements. For instance, the MATLAB Function block can be employed to integrate custom MATLAB code into Simulink models, enabling you to take advantage of MATLAB's algorithm design capabilities and Simulink's simulation features.
