I have a problem setting truck arrival interval and numbers in a container terminal within 24 hours. According to the hour table I have, from 00:00 to 13:00, the number of trucks arrive in the container terminal increases every hour, from 13:00 to 14:00, the number reaches the peak, and afterwards it decreases. I think it's poisson distribution. Do you maybe have an idea how shoud I set the source interval and number?
Looking forward to your reply. Thank you!!!
Using delivery table is a hug task for me, because there are 1912 trucks arriving in the terminal in one day. Besides, the stochasticity cannot be presented via delivery table.
maybe you should check another thread by StevieG (Link), where I posted a solution that uses a trigger+singleproc to handle interval-based arriving-rates. (we switched to German at some point, sorry )
However, note that there may not be exactly 1912 trucks at the end of the day, when you actually want stochastic truck-arrivals.
The source produces parts without interarrival-times; the singleproc handles interarrival-times and the specific time between 2 parts is set by the trigger differently for each time-interval.
Here is the basic input for the trigger:
And here the example result:
I've attached the example-model again.
PS: Another idea would be to fill the delivery-table with specific truck-arrivals based on your arrival-rates at simulation start automatically with a method. So you only define the intervals and arrival-rates and genereate the delivery-table from those parameters.
