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，
# T# r0 k0 p2 C0 ~* t5 ]  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.
1 R. j0 o- P- _9 \; Z+ N  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.
6 U" I& P4 j$ p" l+ m  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 s( k$ ~/ e) E* a, N, s4 o: N  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# Q7 m0 O6 c5 _4 V) `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.

问题：
* ~  ~4 T  S5 a' q/ 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*/
move into Q_process /*Single capacity*/
* D1 V- n( o; A2 J  |# w
" y0 g8 X3 T- c* S# F7 fuse R_A for n 60,10 min /*Resource A*/

send to P_B
: I) c7 ~; o6 rend

P_B and P_C is similar
triangular 30,60,90 min
& i- ~7 F. h% h# S" wu 60,30 min


9 ?- [7 y2 F2 ~8 m# _/ A' Hin 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.


7 P4 w& T' ?' o# D$ q/ gRemember to turn off the animation before you run your model.
