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，
. p( ]+ M/ ?3 P8 X* R2 h  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:
9 ~1 R' Z6 T. P; Q  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 Y) E& v/ N9 I& t! i  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.
2 ?: ~+ b4 f/ C5 ?( t  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*/
0 R: h- k! p3 V. H$ ]
8 r$ U& I8 e3 m$ @: Uuse R_A for n 60,10 min /*Resource A*/

send to P_B
end
8 W. r8 |' K9 K! G
P_B and P_C is similar
- S; M0 D9 G$ s* d! j' ntriangular 30,60,90 min
' L0 a1 s/ Q2 fu 60,30 min
$ w' R$ |" V4 Y- p  m7 U; P% j3 d

in P_C, you need to send to die.
* Y% V5 F) c  ~" P  B
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


, Z8 R! G+ X  m! j; V- J  tRemember to turn off the animation before you run your model.
