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:
  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 t. R' x+ k8 k  A4 k0 E% JSend 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
2 S; i3 |$ z: a$ Y4 T  bmove into Q_wait /*Capacity is infinte*/
8 K  W) e- P, y( D* R% smove 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
* B0 I3 a/ ~; B4 h: K3 ~triangular 30,60,90 min
  @( a, ]: J, O3 T9 M+ n$ T+ y5 iu 60,30 min
  p5 v7 @5 N* M6 L, Z

in P_C, you need to send to die.

& I" U6 C0 U% u# J6 U  O9 OThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
