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，
5 L: X% C2 ^9 b+ P  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.
' Y5 Y- t7 m: o4 J  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 N/ s7 j7 A+ o1 ~4 T: P1 f0 Q- C( D  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.
4 x; J# ~: I1 T5 h2 ]3 w  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 R9 S$ M. @  O! v  l. Q2 U0 z! n) GSend 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.

% s+ z$ b0 n& p! Z5 ^  hAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
! D% d, L  U* J2 G1 Omove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/

send to P_B
end
$ ~9 O: E* B* r4 }
5 E: U4 P  A  A% wP_B and P_C is similar

in P_C, you need to send to die.
2 d) d% G, [- h+ \
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


0 t$ |3 M- D- Y" w# C4 T1 ~0 X; HRemember to turn off the animation before you run your model.
