I am creating a DES and I want the number of entities generated at each unit of time to be the output of a user defined function (the function will be stochastic). I have not been able to replicate this process yet and I am unsure which enity creator block to use.

Hi Alex,
In an entity generator you can set the 'Time source' to be 'MATLAB action' and then manipulate the output value 'dt' (the delta to the next generation time). For example, the following would generate a random number of entites very 2.0 seconds (interGenerationTime). You can make 'interGenerationTime' to be random too. So you would have a random number of entities being generated at random times.

In the above example, 'dt' stands for the delta time to next entity generation. By setting the value of 'dt' to 0, we are essentially asking the entity generator to generate another entity after 0 time units. By repeatedly setting the value of 'dt' to 0 until we reach the required 'count', we are making the generator generate as many entities. Upon reaching the target 'count', we are setting 'dt' equal to 2.0. Which would then make the generator wait for 2 units of time before it generates the next entity.
Best,
Krishna
