So, this is what i thought of. Let me know if it makes sense.

Instead of using the dynamic events option, I just create a delay block. I set the future appointment (per patient type and requirements) (this appointment is linked to the patient itself), and then, when I send the patient home, the delay calculation will be time of appointment minus time patient got home. Having this approach, i make sure that the patient is 'activated' at the proper time, and it is easy to implement if teh patient is a no show, is late or early (and the respective delta time).  

Any thoughts are much appreciated.

Hi Alex,First, 

First, how you generate the appointment day? Is it randomly generated for each patient?  or is it fixed for patient category?

Hello Zakaria,

This was a bit tricky. After the patients get out of the clinic (and go home - i.e. they are not destroyed or exit the system), they go though a bloc that gives them the next appointment. i had to create java classes for this. Anylogic does not directly support this type of schedules. when created, the patients are looking for an available appointment with a doctor [the docs have each their own schedule/timetable]; once the patients gets one, then that patient is always attached to that specific doctor. So, next time that the patient needs an appointment, it will only look at the timetable of his own doc. When it finds an empty slot, it occupies it, calculates how far in time it is, and that is the value of the delay bloc HOME. 

So, it is a fist come first served idea, but, it also checks for availability of the doc. I have some probabilities that also ensure that patients do not need to see the doc every time they come in.

Do not get me wrong, it is not an easy thing to do. And i do not know why no simulation platform incorporated [more complex and complete] schedules.

Hope that helps ;)
