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.
! _+ L7 x8 }" X! a/ O* _  Loads are processed by each operator for the following time:
9 ~; l0 r: M: a8 G) S0 |  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.
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
  `- _; s: W. N3 cmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
! A! R; U& C  h
use R_A for n 60,10 min /*Resource A*/

) A) Q. A  c( e( I! Rsend to P_B
end
& C# b3 y" L7 j+ H
# B7 n0 y. D: b/ r2 e- {P_B and P_C is similar
# K/ J( e+ c, i- f. A5 atriangular 30,60,90 min
u 60,30 min


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.


# E2 l, }3 r5 T$ K! k3 nRemember to turn off the animation before you run your model.
