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:
2 _$ I! F4 f% r$ o5 {9 c2 O" t  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.
% G. _5 ?( k+ {3 Z/ W$ D  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
$ H0 A6 @* `6 _8 V9 _3 m7 Hmove into Q_wait /*Capacity is infinte*/
; Y! Y( c  g  J' a- s0 Qmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
" J+ j& Q) W$ }* o$ M
send to P_B
end

P_B and P_C is similar

1 L5 X- r0 }0 m6 }$ ^in P_C, you need to send to die.

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

' Q  B, V5 g" y* R
Remember to turn off the animation before you run your model.
