Modelling an arrival process with help of the multiserver

When you are modelling a system that uses a certain stochastic arrival pattern of a fixed number of products (or ships, visitors, etc.), I find it easy to use the following atoms to achieve such an arrival pattern: the Arrivallist and the Multiserver.

With the Arrival list, you can enter a number of arrivals at a fixed point in time, for instance:
Time Atom name Quantity Channel
arrival1 hr(0) Product 100 1
arrival2 hr(1) Product 250 1
arrival3 hr(2) Product 500 1
arrival4 hr(3) Product 50 1
...

Connected to this Arrivallist, is a Multiserver. The Multiverser must have a Capacity that at least equal to the maximum amount of products (500) that come from the Arrivallist. If we now set the Cycletime of the Multiserver to a maximum time equal to the interval of the arrival list, for instance Cycletime := Uniform(0,hr(1)), then the multiserver will release the Products uniformly distributed over the desired interval.

Thanks)) have never before used the muliyserver for such purposes
