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，
9 t- X. X: Q6 M; D2 U8 P( H  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:
  G9 k6 J1 N* Z& `5 ^  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
# T- j1 R0 Q8 F" Z" L  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
Send 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.
  l* f) |5 b0 u0 a$ l$ s

After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
0 e- a8 K4 D/ M' Amove into Q_wait /*Capacity is infinte*/

use R_A for n 60,10 min /*Resource A*/

in P_C, you need to send to die.

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