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:
! Z) I% ]9 k/ @) Q  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 r: S3 F' W' f5 E" l4 e3 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.
. f5 D4 }1 N' a3 c0 r1 q  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- F' c& O7 O7 d% `/ O/ y* tSend 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
* B5 F, S0 h; c" M  a# gmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
% A# h* p$ q0 i3 }
! O+ s; f; u) {" o8 b" r3 vuse R_A for n 60,10 min /*Resource A*/
. a0 Q8 O+ f) ]1 I, y/ b! M9 S
. T7 q! U# q7 i  x) P& X& X9 M9 ~9 Vsend to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
* H) H4 b" v$ @9 {4 Wu 60,30 min


in P_C, you need to send to die.
: N2 I3 V7 @8 q
Then 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.
