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，
* l! R% E9 M1 o3 J1 Z. z  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.
' }# {  U$ h! j" k  Loads are processed by each operator for the following time:
$ X: l7 k# i6 i& n0 {  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& _9 \: ?2 {' U5 ?  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.
) t3 @+ i  q% U+ J/ S' |5 lSend 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.
; U9 |0 X7 c, j
问题：
9 Q, p) q( W' ~5 H: bAfter running the model for 10,000 days, what was the average number of loads in each process?

. B; C# |/ k: F( j1 D不胜感激！

begin P_A arriving
# O6 k0 V, J. Zmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

4 l/ C; X& n5 Z, O, A6 tuse R_A for n 60,10 min /*Resource A*/
( Q+ T2 q. \8 X6 J
send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min

4 w6 r* C4 w7 X& F1 @" t2 J4 Zin 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.


Remember to turn off the animation before you run your model.
