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.
! p/ ]; ~( o/ G1 h  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.
, l7 T: \; h4 N& Z2 I  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.

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

P_B and P_C is similar

in P_C, you need to send to die.

( F& U1 o' v" yThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


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