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，
  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.
  Loads are processed by each operator for the following time:
  _& P$ A$ G/ E; r$ b3 b  A' X* Y  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
# W. U% P7 i) X2 E4 n2 q! o$ k  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.

- C+ W# \' u4 l% D问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
' q5 s/ o5 h. t2 B3 Ymove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
$ {4 T5 @2 W7 Q; L
6 n- v) s0 m: I; h4 Quse 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


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.
