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.
! X  \" O& k3 B7 O5 D: G  Loads are processed by each operator for the following time:
$ K8 O$ t- `( v# c0 h  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  _" Q# h* M/ b7 ]3 X. \' z3 B/ r! p  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.
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*/
0 S. G5 k) c1 Emove into Q_process /*Single capacity*/
+ v% h/ I! B' x% r
use R_A for n 60,10 min /*Resource A*/

send to P_B
end
: d9 p2 M) x' A( B4 w" ]
P_B and P_C is similar
triangular 30,60,90 min
4 S) n5 s+ b- ?6 G* y, au 60,30 min


in P_C, you need to send to die.

: z9 H0 o( X) B! h3 u) T/ C) t" PThen 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.
