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，
$ b5 J' q* L) l1 O2 o# i/ j  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.
* R$ d! M/ y$ r  A, p  D4 g  Loads are processed by each operator for the following time:
  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.
! o# V$ G4 F# w% _: |2 G& F. M  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* I) w: ?. p8 }1 SSend 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.

问题：

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*/

send to P_B
end

P_B and P_C is similar

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