Custom normal distribution for the arrival of customers

I'm working on a model that simulates the arrival customers. The number of customers and the arrival time vary between 11.00 am and 02.00 pm. They can be approximated by a normal distribution. There are two distinctive peaks at 11.45 am and 01.00 pm.

I already found my way to the parameters of the normal function in flexscript. Is there a way to change the number stream into the model time so that I can use this function to simulate my customer stream? (The solution would be 2 different sources with separate functions for the peaks).

Summarized: I want to create a normal distribution that doesn't use the inter-arrival-time but rather the actual model time.

Software Version:

FlexSim 23.2.0

flexscript source normal distribution

Sure - you can generate your arrival times using the distribution and then schedule them - which you could for example implement in a process flow with a delay to the arrival time.

You could also try setting up the datetime source activity in a process flow with an Offset Variability that is/are your normal distribution/s.

Hello Jason,

thank you for the quick response. The date time source solved my problem after I figured out how it worked. Thanks again for the help.

I'll upload an example for anyone that needs the same solution.
