本人初学auto mod,有一道题目希望大家赐教

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，
  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.
  Loads are processed by each operator for the following time:
& Z1 n( P; ?' _* H) f, {: K  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- i( T' k0 `0 K5 o( g, C6 S5 x  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! U# ^8 b* Y- x8 t4 qSend 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.

; K3 y5 {4 r) i) H问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
/ Q1 C, X) w, _8 G0 O, hmove into Q_wait /*Capacity is infinte*/

send to P_B

P_B and P_C is similar

in P_C, you need to send to die.

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