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，
- x% j' _' w: _, \' u! d0 O' h3 i  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.
% u3 L) M% N- d% }( L  Loads are processed by each operator for the following time:
% K8 u: R2 C  t+ Y$ U+ P( O  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
2 Q9 w4 n* d" g0 Z: n. ]  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.
8 b: |( O2 h+ z1 P- h  @  U% g0 M- bSend 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*/
$ @/ G# O& d  J1 fmove into Q_process /*Single capacity*/

( r. Q7 N/ S) e* `+ _use R_A for n 60,10 min /*Resource A*/
; M/ N4 m. a, V/ q, P
send to P_B
end

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.
