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，
  @. o) \& @* N/ P' v4 W4 G& w  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.
. t& M1 T! i, K* A4 [+ O2 ?  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.
! M1 T# S- d" A: a+ Y8 G  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.
: N+ w% i" W- ]6 U! 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.
$ b+ K9 H" f3 v9 |/ P+ L* d
问题：
$ |! [" X4 E6 n" L- r0 Y4 ?2 L2 zAfter 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*/
4 w3 _, `! X% M! j
use R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar
# J' V8 q: P2 ?7 Y0 l$ otriangular 30,60,90 min
4 d& ]' k/ v3 j! v7 fu 60,30 min


in P_C, you need to send to die.
  y% y+ H5 N9 G* Q+ j5 {
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
9 C* J6 V0 J( n& B

6 `: P8 T) n2 _Remember to turn off the animation before you run your model.
