Determine patients incoming and go to others location with probability

have a question about a hospital simulation model. I determined the number of patients coming in at each time point using the Poinson distribution. And what I'm stuck on is I would like to define that for each period of time patients come in, coming in every hour, each hour has a different proportion of the number of people coming in. For example, 7:00-8: 00 patients arrived with a poisson(34) distribution. Of these, 26% of the patients arrived at OPD_MED , 25% of the patients arrived at OPD_PED , and 34% of the patients arrived at OPD_PED . Of the number of patients that come in must go to OPD_SURGERY and 15% of the number of patients that come in must go to the ER. If only 1 patient comes into the system in that hour, choose the location that will go with the % value. I write it in process flow, but I don't know how to direct decision.

Demo HC.fsm

I have also attached the model file. Including a picture showing the distribution of the patient's entry

in each time period and the probability that patients are divided into different locations.

As for the question I would like to answer is

1. The patient distribution schedule has been distributed for each period. in each period I want to assign a location to go after entering the system for that group of patients. with the percentage as shown in the figure

2. How do I have to write in the process flow in order to execute the above conditions?

Here is an example of one way you could do this. demo-hc_1.fsm

I added a new Label column to the Source activity in the Arrivals flow and made it an Array label. In that array I put the 4 percentages:

Then in the Decide activity in the Patient Flow I chose By Percentage in the Send Token To field and added 4 sections. Each references one of the percentages on the Percents array label.

Last question, In each time not allow all patients to come into system all together. such as If 00:00-01:00 need to have patient 100 patients come into system but not allow come into system at the same time. random come come into system may be 2 people come at the same or 3 people come at the same time like this and at the duration need to get patient complete 100
