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:
/ F. V2 A% o$ b3 k* c  ^! b( \- z  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& i( l$ L* v- g+ G) r3 R5 q* _  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.
# H2 P% n' c% PSend 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.

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
' p4 G$ D$ B& M& U: Y
send to P_B
end

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