Hi:
I have a simple queue with two possible outcome. The customer could leave the system after waiting for 3 s in the queue. Before I use a program from Felix and it works for case when the arrival time starting at 0 s. However, when I uncheck the starting at zero box, the result does not seem right.
The program produced System Content Vs Time as follow.
But the correct one should be
How do I coorect the program to get the right answer?
The program is attached. 第1題.fsm
What you believe to be wrong relates to the logic @Jason Lightfoot provided you here.
With Arrival at time 0 being set in the source, the inter-arrival time will be evaluated for the first time after the first item was created. Without, it is of course evaluated before since it dictates the arrival time.
Since you increment the row label in it, it will have a value of 2 when the first item is created, resulting in the first process time value being skipped.
Either set the reset value for the label to 0 or increment the value in the On Creation trigger after assigning the item label instead of doing it in the inter-arrival time field.
Hi:
I tried to reset value of the label to 0, but to no avail. The following is the setting.
The result is as follows.
There is an error in console. Anything is missing in my correction?
1 + current.row++
My mistake, sorry for that.
