刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,
) w0 p) ~8 c$ M- I' l/ O* V  Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.1 Y* g0 w, x. F) e& G8 s
  Loads are processed by each operator for the following time:
6 r) l. L1 s4 G* `8 a5 _  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ D. ^9 J( V% n
  Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.
/ d/ o+ e, S. W. Q6 H; t! m  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; O/ k2 a+ t# K' rSend loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers., w6 W' T0 g8 U( O: Z

' {9 s4 O8 J& v8 ]+ j( L3 m问题:' A6 v; ]' _! {* |
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!

in P_C, you need to send to die.

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

Remember to turn off the animation before you run your model.
