How can I model the waiting time in Simulink?

I'm struggling to model the saved time between 'do something' and 'do nothing'.

More specifically, I'm making a model that shows how much we can save the time after we equip something. I used 'Entity Generator' module to make entities randomly. At this circumstance, how can I model the reduced time of 'do something', compare to 'do nothing' of each entity? I have no idea about which module i can use and how to do this...

I use version of 2021.

Hello Min,

You could make use of 'Enabled subsystem' for modelling waiting time. The following example illustrates the idea:

1) The 'Enabled subsystem' contains the logic which needs to wait until a particular condition is met in order to execute.

2) The condition is modelled here using a 'MATLAB Function' block whose output decides when to enable the subsystem. The attached model illustrates that the MATLAB Function considers the value of 'Constant' block which changes upon clicking a 'Push Button' to decide the output.

In a similar manner, you could modify the logic within 'MATLAB Function' block to appropriately control the enabling/ disabling of subsystem and hence model the waiting time functionality. The simulink model is attached for your reference. For information about 'Enabled Subsystems' you could have a look at the documentation page: Using Enabled Subsystems

Hope this helps!
