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，
, a) E! X- H" T  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.
* Z3 q! O: W. B/ p' c( J4 z  Loads are processed by each operator for the following time:
3 s5 J- N6 z7 k  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
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.

" M+ `6 `7 g2 ^) q) k- L! w7 M问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
& ^1 q! }( H# Z6 nmove into Q_process /*Single capacity*/

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

send to P_B
end

8 ~4 P) \1 B7 U8 R) N% R3 b0 ZP_B and P_C is similar

in 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.
