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& l5 U4 j% \+ n) R0 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.
) K2 `4 W9 @( `9 u& r( u  Loads are processed by each operator for the following time:
+ M$ H/ H# G& e  ?9 P$ o, n  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 j* S, d8 C5 s# 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% [$ s  e: n9 V. H  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.

问题：
- \' L. N/ R" B' U- g8 M, j" b/ bAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
- O. u, r9 n& s! x9 ]" kmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

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

send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min
. z* A+ K' C. ^* M+ K5 Y7 B

in P_C, you need to send to die.
  C$ `$ L9 [! ?
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
% t. s, T7 W2 ^+ S

& s8 \* z( R+ [( O, r, LRemember to turn off the animation before you run your model.
