Changing properties of source block for different states in a statechart

Question

I have a model in Main that looks like this:

The source block is set to uniform(4,8) hours in interarrival time.

1. When the statechart goes from "normalWeather" to "storm" I want source to stop injection
2. When the statechart goes from "storm" to "normalWeather" I want the interarrival times to come back to uniform(4,8) hours.

What is a suitable solution for this problem?

Answer 1

Set the source block to inject instead of interarrival time. Then add a transition of type timeout from normalWeather state to itself. Set the timeout as:

uniform(4,8)

And set the action as:

source.inject();

That way, as long as your agent is in the state normal weather, agent injections will occur at your desired rate.
